2017 NJQRP Skeeter Hunt - my sincerest apologies!

Thank you to all who participated in the 2017 NJQRP Skeeter Hunt yesterday. So far, from the log summaries and soapbox comments that I have received, it would seem you all had fun despite the crummy band conditions.

I apologize for not being able to participate and work many of you this year. I was stuck on I-95 yesterday for almost 10 hours, returning home from Virginia where we took our son Joseph on a college visit. I thought I might get home in time, early enough to catch the last part of the Hunt; but it was not to be.

Please remember that log summaries and soapbox comments are due NO LATER than Midnight, Sunday Night September 3rd.  You can send them to w2lj@arrl.net. Each log summary received will be answered by a confirming e-mail - so if you don't hear from me within a day or two, please try again!

Don't try this at home!

Before I go into today's blog post, I have to mention that for Catholics, today is the Feast Day of St. Maximilian Kolbe, SP3RN. St. Max was a Franciscan Friar who was interned at Auschwitz during WWII.  After three prisoners escaped, the Camp Commander responded by sending 10 prisoners to their deaths by starvation.  One prisoner plead for his life as he had a wife and children.  Upon hearing this, Fr. Max asked to take that man's place.  His request was granted and he was the last of the 10 to survive. Maximilian was injected with carbolic acid to end his earthly life on August 14th, 1941.

Greater love than this no man hath, that a man lay down his life for his friends.

Catholic Hams have fondly and unofficially taken St. Max on as our patron saint, the patron of Amateur Radio operators, worldwide.

St. Max, ora pro nobis!

They say that confession is good for the soul - so I will confess. Yesterday, I replaced the coax running out to my Butternut HF9V.  The coax has been there for umpteen years since I put the vertical in place in 1999, about a year before my son Joey was born. It's been a while now that I've wanted to replace the coax and last Autumn, I purchased some 9913 from DX Engineering, My good intention was to run that coax out to the antenna before last Winter began.  You know what they say about good intentions.

Yesterday, the weather for the chore was about as near perfect as it gets. It was sunny, warm, but not hot, with a slight breeze and low humidity.  I began by putting on the work gloves and pulling up the old coax. It's been such a long time since I put that coax down; and I was mortified by what I discovered.

Connected to the Butternut's matching stub was a barrel connector and then a 100 foot run of LM-213.  At the end of the 100 foot run was another barrel connector and a 25 foot run of some more LM-213. Then, as if that wasn't bad enough - there was yet another barrel connector and a final 25 foot run of RG-8X leading directly to the operating bench.

What the heck was I thinking?!?  This was coax hack job of the century! I still can't believe that I did this; and if I hadn't seen it with my own eyes, I would never have believed that I could do such a sloppy, piecemeal job. The only thing that I can think of was I was so tapped out after purchasing the Butternut, that I just used whatever coax I had on hand to get the job done. 

All those barrel connectors! All that loss!  I must have had an ERP of about 2.5 Watts! It seems a miracle that I made any QRP contacts at all, let alone all the DX and states I have worked with that cockamamie set up. I am truly amazed at what a lousy job I did - EXCEPT in one respect.

When I removed the electrical tape covering up those barrel connectors and their accompanying PL-259s, they were as shiny and new looking as Day One. And I owe that to an article I read somewhere, way back when, maybe it was on QRP-L.  When I made those connections, I first wrapped the coax and the connectors with electrical tape.  Then, I covered that with a layer of plumber's putty. The plumber's putty was followed by a final layer of electrical tape.  After some 18 years, the connections were bright, shiny and there was NO sign of any water intrusion, whatsoever. And considering the coax was laying on the ground through some very harsh Winters and at least three major Hurricanes, Floyd, Irene and Sandy, that's pretty darn good.

There was one section where the jacket of the LM-213 got chewed up pretty badly from lawn mower hits.  To prevent that, this time I elevated the coax as it ran along the back fence.


I used garden fencing stakes, spaced out at about 5 foot intervals and I cable tied the coax to the stakes to keep it off the ground and away from the angry blades of my coax eating lawn mower. Once I got to the chain link fence running along the side perimeter of the yard, I then cable tied the coax to the top tube.  My new run of one piece of 150 feet of  RG-9913 is safe and sound from gasoline powered lawn tools!  There's only one barrel connector, where the terminus of the coax meets the Butternut's matching stub. and you can see that little lump in the picture, above.  Now maybe I'll get a bit more of that precious 5 Watts into the antenna and out into the aether.

Later on, in the afternoon, after getting home from my monthly volunteer stint at the soup kitchen, I soldered on the PL-259 to the radio end of the coax.  I plugged it into the KX3 and was happy to see a VERY easy match made by the autotuner on all bands.  Maybe a 1/2 to one second "BRRRRP" by the relays in a few cases, and in the rest, there was no match needed at all.

There's peace of mind knowing that I now have a proper run of low loss coax out to my vertical.  I'm also going to change out the coax to the W3EDP.  That's a straight forward exchange, and I figure that as long as I'm doing one, I might as well do both. I'm happy to state that the coax currently running to the W3EDP is not a hack job conglomeration like what was running out to the vertical !

I'll NEVER do that again and like they say on all those shows on TV = "Don't try this at home!"

SOTA envious

I have to admit that I am more than "sorta" envious of those Hams who activate the SOTA summits. I look at photos like these from Steve WG0AT, and I'm just beside myself, admiring the beauty of the landscapes and the tenacity of those who go to these places.





Yeah, there are summits in New Jersey (EVERY state has a few), but they're nothing like these. Well, according to geologists that I have read, the Appalachians were once taller than the Himalayas at one point, but that was about a bajillion years ago. What we call mountains here on the East coast are mere hills compared to the Rockies. I've been fortunate enough to visit the Rockies and even come close to the Alps in Switzerland, so I can affirm that comparison.

Instead, with the limited time that I have to devote to portable ops (employed full time with a mortgage and two kids going off to college soon), I resort to POTA and NPOTA (when it was active) for my outdoor venues of operation.

Because those opportunities present themselves so seldom, I like to take the moment to enjoy the place that I am operating from. No long hikes to summits with beautiful vistas of multiple states present themselves to me; but in the parks that I do go to, I am surrounded by nature and beauty all the same. There's something special and wonderful about being bathed in sunshine and fresh air, and seeing trees, and listening to the sound of the breeze rustling through their leaves, while at the same time watching and listening to brooks, streams, rivers, wild life and what have you. Whether you're perched on a mountaintop or operating your QRP gear from a picnic table in the local city park, I would hope that all portable ops mavens take the time to enjoy the beauty of their surroundings and not dismiss that beauty for the tunnel vision of just chasing QSOs. Portable ops should be about way more than just a bunch of QSOs. Heck, I can do as much from my cinder-block-walled-in bunker of a basement shack.

Don't miss the forest for the trees!  Take the time to smell the roses. Take a moment to breathe deeply, enjoy the fresh air and Nature in all the glory of your surroundings! Life is precious - enjoy it and revel in the moment. And should you not make any QSOs, don't be disappointed. You had the opportunity to go and be somewhere that is beautiful, and that is far more precious than just making a few contacts on the radio.

My fist is BAD!

Last night, I was asked to run the monthly county ARES net. After that I attended our Assembly's Knights of Columbus 4th Degree meeting. A pronouncement has come from K of C HQ in Connecticut which has not gone over well with the membership. I won't bore you with the details, but the meeting was interesting.

When I returned home, I went down the basement to add a link to the Skeeter Hunt roster on the Skeeter Hunt Website. While I was doing that, I decided to join in on the monthly NAQCC sprint. A few weeks ago, I received my W2WK straight key, so I decided to take it for a spin.

The key is a beauty, a sight to behold.  The action and feel are superb. My fist is not.  Sadly, I've gotten so comfortable with paddles and keyer that my "manual" fist has atrophied.  It improved a little bit as the night went along; but I have to publicly apologize to the NAQCC members who worked me last night. You know your fist is bad when you feel yourself grimacing while you're sending. I think that if you looked up the word "ugly" in the dictionary, there would have been a picture of me behind the key last night.

I am terribly sorry for my crummy fist and the torture I put you through.  I need to practice more and hopefully, by next month's sprint, I will sound a whole lot better. When you've hit rock bottom, there's no place to go but "up".

Multiplying like rabbits!

It seems like there's never been the bonanza of QRP radios available like there are today. What follows is not an accurate timeline, just impressions upon my memory. For years, you had the Ten Tecs and the Heathkits, the SGC and QRP Index radios and various homebrew rigs. Then came the Sierra's and the Small Wonder Labs offerings and then Elecraft burst onto the scene.

IMHO, ever since Elecraft, it seems like there's been a non-stop parade of introductions of commercially available QRP radios. And this is a good thing.  More people are tossing there hats into the ring, and the offerings are becoming numerous. Competition is a good thing and the various models are a benefit; as no one radio will fit everyone's taste, style or operating habits.

This is the latest one I've come across, offered by Appello-funk out of Germany - the Aerial-51 SKY-SDR




Here are the specs according to their Website:

This 11-band All-Mode QRP transceiver is manufactured in Europe and combines SDR / DSP "Direct Conversion" technology with ease of use.

The device does not require a computer to operate, has almost all the characteristics of a "large" SDR transceiver and is thus particularly suitable for demanding QRP  and portable radio operators. The future-oriented RX is equipped with all common DSP functions, eg user-definable (extremely steep) filters,  noise reduction (NR), noise blanker (NB), adjustable AGC, and audio equalizer.

The built-in BANDSCOPE shows 24 Khz above and below the QRG and also works with TX.
An outstanding feature is the "differential ADC" or "differential DSP"  It provides very low noise on reception, which is particularly noticeable on the lower bands 160-40m.

The SKY-SDR transceiver is also characterized by a clean TX.  It comes with hand-held microphone, voice processor, audio equalizer, VOX, SWR & Power Meter, built-in keyer (A / B mode) and dual-mode CW (CW / CW reverse).  AM, FM and DIGI modes are also supported.  The device has a USB CAT port (with FTDI), LINE IN / OUT for DIGI Modes, and an I / Q output for computer monitoring.

Perhaps the only QRP radio with built-in band scope.

This and other unique features make it the most interesting QRP radio in the world.

Aerial-51 "SKY-SDR" 350 mA / 310 mA without illumination
TX Power Consumption : 1 to 2A
Dimensions: (WxHxD) 147x60x107mm (without buttons)
Weight: 580g

GENERAL TRANSCEIVER SPECIFICATIONS Technology Solid State SDR-DSP Direct Conversion
Frequencies / Bands 1.8 MHz to 54.0MHz 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, & 6m Bands
Modes AM, CW, DIGI, FM, LSB, USB CAT: USB2 (FTDI Chip) Digital Modes JST, PSK, RTTY, SSTV, etc.
LINE IN / OUT 3.5mm Jack
Output Power 5 Watts (typical) (foldback protection for high SWR)
Antenna 50 Ohms (nominal) BNC Connection
Voltage requirements 10.5vdc (min) to 15vdc (max)
Fuse : 3.15A, 250V, Slow Blow
Current Drain RX: 350mA; TX:

First impressions - it seems to be almost an exact copy of the LNR LD-11 radio. The specifications and similarities are strikingly similar, in many areas. However, the LD-11 claims to output as much as 8 Watts, while the Aerial-51 claims to output 5 Watts, max. Despite the difference in output claims, I'm wondering if they're the same radio in slightly different housings.





The Aerial-51 is priced at 739 Euros, which translates to $871 US.  The LD-11 from LNR is priced at $790, but seems to be out of stock at the moment.

The other thing which caught my eye was the statement, "Perhaps the only QRP radio with built-in band scope." My mind immediately went to the mcHF radio, which has a nice, full color waterfall display.  Perhaps, "one of the few QRP radios with a built-in band scope" would have been more accurate.

Like I said, so many rigs to choose from - we QRPers have never had it so good!

Plans

I think I have mentioned this before. A quote from Robert Burns, "The best-laid plans of mice and men often go awry".

That described my yesterday. My plan for the day was to replace the coax to the HF9V with the 150 feet of RG213 that I had purchased from DX Engineering last Autumn. I was just about to get started when my wife Marianne called out, "Larry, there's something wrong with the washing machine!" Sure enough, she had loaded the machine and was about to start a wash cycle, and it filled partially and then just ........ stopped.  Dead in its tracks.

Step 1 - Cancel the cycle and get the water out of the machine.
Step 2 - Remove partially wet laundry to a basket so that my XYL could take it to the local laundromat.
Step 3 - Breakout the laptop and Google and YouTube.

These machines are so sophisticated these days with microprocessors, control boards and touch panels.  Gone are the days when all you had was mechanical timers that regulated and controlled the wash cycle. Luckily, through Google, I found a YouTube video which described how to run a diagnostic on the washing machine.  It boggles my mind to even write "run a diagnostic on the washing machine."

Anyway, I did that and got a F51 error which seemed to indicate a problem with the rotor position sensor, whatever the heck that is. An accompanying article suggested unplugging the machine for two minutes to clear out the capacitors on the control board in order to reset the microprocessor, and then run a wash cycle, as a first attempt to fix the problem.

I grabbed a few dirty pieces of clothing and tossed them in the machine along with some detergent. Fingers crossed, I closed the lid and punched the proper buttons. Everything worked!  It seems the problem is solved with the exception that the spin cycle seems a bit louder than it used to. A new rotor position sensor runs about $100, so if it eventually gives out and we get the same error again, I'll order one of those and will give it a go.

Needless to say, figuring this out and then carefully monitoring a couple wash cycles took a big chunk out of my afternoon. On the bright side, while waiting for a cycle to get done, I walked over to the other side of the basement where my shack is and I put a PL259 one on end of the RG213. Putting a PL259 on RG213 is extremely simple. I found these instructions found on eHam to be most helpful. They were written regarding installing a PL259 on LMR400 - the procedures are the same:

"Any standard PL-259 fits LMR-400 exactly, and perfectly without any modification to the cable or the connectors.  I've installed hundreds of these on LMR-400s and use ordinary Amphenol 83-1SP PL-259s.

You *don't* peel back the braid of LMR-400 for this operation, where'd you hear that?  That won't work at all.  The correct procedure is the same as installing a PL-259 on regular RG-213/U.

The braid must remain in place exactly as it was originally, and the only thing you strip is the black vinyl jacket.  Leave the braid right where it was, under the jacket and tightly braided over the foil.  The best way to prepare the LMR-400 cable end is with a sharp (new) single-edged razor blade, cutting through the vinyl jacket, braid, foil and dielectric all in one single slice and leaving only the center conductor, stripping all else (with a single cut) back about 3/4" from the end of the cable.

Now, you have a copper plated aluminum center conductor sticking out and the rest of the cable fully intact.

Now, measure back 1/2" from the edge of the vinyl jacket and use much less pressure to strip only the jacket, and leave the braid, foil and dielectric intact.  This only takes gentle pressure, not the several pounds the first "strip" requires.

Pull off the jacket.

Push the PL-259 over the end of the cable so the center conductor protrudes through the end of the center pin and when you hit an obstruction, that will be the cable jacket hitting the internal threads in the PL-259 body.

Rotate the PL-259 body clockwise while applying gentle pressure to the connector, and it will screw itself on to the cable jacket.  About four full rotations are required to fully assemble the connector on to the cable, and when you're done, it won't twist on any more, and you'll see the braid showing through the PL-259 body solder holes.

This entire process takes fifteen seconds if you know what you're doing.  It can take forever, and never come out right, if you don't.

WB2WIK/6"

I am hoping and praying that the weather next Saturday is good and will allow me to get this done. As of right now, the forecast is for a cloudy day, but with very low chances for rain. I'll take it. If I can that done and the coax on the W3EDP exchanged out, I will be happy camper.

This morning, I had to chuckle when I read John K3WWP's diary entry for yesterday. He was writing about his DX Streak QSO for the day:

"Sun Aug 06 2017 8:50PM - It doesn't get much harder than this. I hate to make a DX station work so hard to get me in their log, but some folks have a tremendous amount of patience and will stick with someone till the QSO is complete. They will put other station trying to break in 'on hold' so to speak and continue to work with the one station till he is in the log or it becomes hopeless. That pretty much describes what happened between me and SP5ELA on 40M a little while ago. It must have taken about 2-3 minutes for him to get my call, but he didn't give up. I guess I must have sent my call about 30 times before he got past K3W and finally sent K3WWP TU 559. Thanks to him, the DX streak goes yet another day."

What caused me to laugh was when I saw the station he was trying to work, SP5ELA and then going back to his words - "but some folks have a tremendous amount of patience".  I had to send him an e-mail basically telling him that, being of Polish descent myself, I'm not sure if it was a matter of patience so much as it was probably more of a matter of stubbornness! I've always been told by my grandparents that stubbornness is a trait common among the Poles. And I find it true with myself, once we start something, we're not likely to give up on the task, no matter how long it takes!

23 years under his belt!

As my regular readers know, I often mention John K3WWP here in the pages of this blog. No doubt, I'm a fan of his. John is a "QRPer's QRPer".  His whole Amateur Radio career revolves around QRP, Morse Code and simple wire antennas.  He is dedicated to showing that you do not have to have an overly elaborate set up to enjoy Amateur Radio; and that in fact, it can be done with very moderate or even meager means. He is dedicated to showing how much fun and rewarding all this can be. If there was ever anyone who deserves to be in the QRP Hall of Fame, without a doubt, John Shannon K3WWP deserves to be there.

Tonight, John will embark on trying to begin his 24th year of making at least one QRP CW contact s day.  Allow your mind to wrap around that.  It's easy to read it, it's easy to say it. But take some time to think about that. That is over (not sure how many Leap Days are in there) 8,395 daily QRP QSOs in a row, completed.

Over 8,395 days uninterrupted. That's quite the feat when you take into account all of the multiple solar lulls, CME's, solar flares, bad weather, equipment mishaps, and personal circumstances that could have easily ended this streak early on. Nevertheless, John endures and persists through it all, and continues to make the QSOs - with 5 Watts, or less. I'm sure this streak will never be equaled or surpassed. It will probably never make the Guiness Book of World Records, or even be acknowledged by those outside the QRP Community.  But it's there and we know, for a fact, what can be done with QRP.

So the next time someone tells you that QRP is a joke, or it's a waste of time, that it's a matter of luck and not skill; or that all the success is totally due to the receiving station, OR that "Life's too short for QRP" ....... stand fast and unwavering and think of John K3WWP. Chuckle quietly to yourself and move on, knowing that the power and worth of QRP and CW have been more than adequately proven - over 8.395 times in a row.

Caveat Emptor!

I saw this sobering e-mail today from Doug Hendricks, KI6DS on QRP-L.  Since that is a public forum, and Doug is addressing the QRP Community at large, I am going to re-post it here.  It's a long post; but worth reading to the end. I will add some comments of my own at the end.

[QRP-L] Caveat Emptor, or my experience with buying a Chinese Rig

Last May, I decided to buy a modern, up to date transceiver with all the bells and whistles.  I wanted something that I could take out in the field and it would have all of the operating aids available today.  I looked at the KX3 and the KX2.  Wow, nice radios, but oh my, the price.  I can afford the radio, but can I justify spending over $1000 for a radio?

So, I decided to do some research.  I found a neat radio on the web.  It was the McHF from England.  It is a kit, and it has a lot of smt parts. Then, while doing more research, I found a Chinese Radio called the RS918ssb.  It is a commercial product made from the information provided by the McHF group, which is open source.  There is nothing that is illegal about the Chinese taking the information from an open source project and making a commercial product, as long as they follow the open source guideline.  The interesting thing was the price: $380 delivered.  Wow $380 for an all band ssb/cw/data transceiver?? that puts out 15 Watts and has a built in touch screen with pan adapter.   I thought about it for a week, went back and looked at the KX2 and the KX3.  Contacted the company in China and asked a couple of questions, which they promptly answered.  Larry was my contact person.

After spending a week mulling it over in my mind, I decided to take the plunge.  But I used Paypal with my credit card to pay for it.  I wanted to have some backup if the deal went south, and Paypal and Visa both have policies to protect the buyer.  Feeling that I had adequate protection I placed the order.  Larry said it would ship later that week and he would let me know when it shipped.  When I didn't hear anything for a week, I emailed him.  He said, oh so sorry, we had a production problem waiting on parts, but no worries now, parts are here.  Radio will ship next week.  10 days later the radio finally shipped, after another round of emails and my threatening to cancel the order (in hind sight, that would have been a smart move).

The radio arrived, and boy did it look good.  Nice case, small, and all of those features.  Just what I wanted.  Hey, I got this for $380, it has a pan adapter built in, and I saved a ton of money by not buying a KX2 or KX3.

Well, let's move ahead a week.  I play with the radio on receive, go over to a friend's house to try it on his antenna for the first qso.  We hook it up on SSB, and it sounds great.  No problems.  I take it home, put up my antenna at my new shack, (off center fed windom), and decide to make a cw qso.  Plug in the paddles, make sure the swr is 1-1, and start calling CQ. No answer.  I call for 10 minutes.  Nothing.  Oh well, band is very quiet. I'll try tomorrow.

The next day, I go out, decide to check in to the 9AM net on ssb.  When I key the mike, the touch screen goes blank.  What?  I try to adjust the radio, nothing.  I call Steve "Snort Resin" Smith.  He suggests to check the current draw.  I key the radio on 1/2 Watt power out.  Screen goes blank, 525 mA of current draw.  Then I change the power out to 15 Watts. Still screen goes blank and 525 mA of current draw.  Uh oh.  Problems in River City.  My radio has a problem.   I email Larry and tell him what is going on.  It takes him 3 days to answer.  He says I will check with engineers and get back to you.  2 more days, finally he answers one of several emails to him.  He says to make sure power supply is adequate.  I tell him it is 25 Amp supply, and it is adequate.  No problems with power supply.  Larry says I will check with engineers.  3 days later, no answer. I am not happy.

I email Larry and say the engineers can't fix my radio if they are in China and the radio is in California.  I tell him there are 3 options:  First, I return the radio  and they fix it.  Second, they send me a new radio and I send my radio back, third, they give me a refund.  No reply from Larry for 2 days.

That's it.  I am fed up with this.  I file a claim with Paypal.  No response from Larry.  So I escalate to a dispute and ask for arbitration. Larry responds.  I ask him what is going on?  He says  he wants to fix the radio.  I say no, I am tired of dealing with this mess.  I want my money back.  He agrees to a refund, but I must sent the radio back, with tracking.  I check with all the shipping companies. It costs me $153 to ship the radio back with tracking.  I checked everywhere.  That is what it cost me.  So, I spent $153 to get $380 back,  This is an expensive lesson.

I forgot one of the cardinal rules of buying something.  What kind of service and support is available if something goes wrong.  I just didn't think about it.  I knew it, but I was so excited about the price, that I was blinded.  I paid for the mistake.  $153.  I learned an expensive lesson again.  Education costs. thank you Chuck Adams, who is fond of saying that.

How does the story end?  I called Elecraft, and bought a KX2 for $1061 delivered.  It has the built in tuner, battery and battery charger.  That's it for accessories.  Ordered it on Friday, delivered on Tuesday.  Free shipping.  Had a question 2 days later.  Called the factory. Question answered. Took 5 minutes, not days of waiting on email from "Larry".  And if I have a problem, I only live 45 minutes from the factory.  I can drive my radio over there to get it fixed.

So there is my story.  I tell it for information for my fellow qrpers.  You decide if you want to buy a radio from China.  But before you do, find out who is gonna fix it if something goes wrong, and remember, it is expensive to return a radio to China.

KI6DS

I will be the first to admit that I have been guilty of purchasing radios manufactured in China.  Those have been VHF/UHF handhelds and a mobile rig. On that score, I'd like to make a comparison. To me, and this is just my opinion, buying a VHF/UHF radio, whether it be a handheld or a mobile rig is akin to buying a car, in that you expect to purchase more than one in your lifetime. Purchasing an HF radio on the other hand is akin to buying a house. It's a major investment; and for most of us, unless you have very deep pockets, it's an investment that you are going to be bound to for a significant amount of time. So in the case of HF rigs, it pays to get the best you can afford and that the product be from a manufacturer with a proven and reliable track record (of both merchandise and service).

For me (again, personal opinion. YMMV) the purchase of a VHF/UHF portable or mobile unit is of lesser consequence.  I use them less (way less!) and I will try and get away with as much as I can in that regard.  If the thing breaks or gets stolen or dropped, I'm not going to go into coronary arrest as if the same thing happened to my HF radio.

If you're a technical genius with an EE degree behind your name, then perhaps purchasing a Chinese HF rig is less of a risk for you.  For us mere mortals, however, we might want to stay away from questionable sources.

FOBB 2017 in the books!

The Flight of the Bumblebees for 2017 is in the books!  Many thanks to Rich Fisher KI6SN and the Adventure Radio Society for sponsoring this "classic" Summer time QRP event.  I use the term "classic" because this was the 20th Anniversary of FOBB. It has provided so much fun for so many people throughout its two decade history that it deserves the status of "Classic".

The weather in Central New Jersey was about as perfect as it could be. When I left the house at Noon, it was sunny, with crystal blue skies, without a cloud in them. The temperature was a very comfortable 77F (25C) with low humidity - near picture perfect.

When I got to Washington Rock State Park, about 20 minutes later, I was greeted with a park that was nearly empty. Just a few people and all the picnic tables were vacant.  I went to my customary table and went about setting up the station.

First thing was the antenna of course. I'm not trying to be boastful; but I am getting darn good with that Joplin ARC antenna launcher.  As long as there's no stiff cross breeze to mess me up, I can place the line in one shot.  Today was no exception.  I got the "bullet" over a limb in the  40 to 50 foot high neighborhood and hoisted the PAR ENDFEDZ 40/20/10.


It's always hard to get a good photo of a wire antenna in the trees.  The white arrows point out the path of the antenna and the yellow arrow points to where the coax ends and the PAR begins. The end of the antenna actually ended up going a bit over a limb that is way higher up and is out of the photo. I had the station set up with plenty of time to go.  It afforded me the opportunity to make a few postings on social media, both Twitter and Facebook.


I decided to use my newly built QRP Guys KX single lever paddle for the entire event.  I wanted to see how it would hold up under Sprint conditions; and whether or not I would fatigue from using it; or other wide become uncomfortable.

The station power supply was my older Radio Shack 5 aH SLA and I think that today was its last performance.  It exhausted itself rather early on, even though I had recently charged it.  I got it used and it has served me well for the last seven years or so.  No regrets there; and I certainly got my money's worth out of it (it was free).  Luckily, my lithium battery is always in the backpack and it had more than enough capacity to carry me through until the end of the contest.  The reason I didn't use it from the start was that I had my suspicions about the health of the SLA and I wanted to see if they were correct.  They were.

Band conditions were not the greatest, to say the least.  20 Meters was the money band today; and I was disappointed with 40 Meters.  Usually 40 Meters yields me as many QSOs as does 20 Meters. Not today.  40 Meters was noisy and QSB was bad. Signals were either 599 or 449, and often they went back and forth between those two extremes whole I was trying to copy an exchange.

I ended up making 29 QSOs altogether. Not great, as I've certainly done better in past FOBBs. But given the fact that we're traveling down the downside of the sunspot cycle about as fast as the QSB was today, it could have been a lot worse. 19 were made on 20 Meters and the balance on 40 Meters, a 2/3rds to 1/3 ratio, where normally for me it's about even or closer to even. Some calls that stood out - Greg, N4KGL had the loudest signal that I encountered all afternoon. I also ran into AB9CA, NK9G, K4BAI, WA5BDU, WD8RFI and VE3LFN among many others.

I also received a post on Facebook from Mike KC2EGL who was with John K3WWP working N3AQC in PA that they heard me calling CQ on 40 Meters. Unfortunately, I wasn't able to hear them calling me and wasn't able to get a QSO in the log. Perhaps if I had done something a little bit different - more on that below. Hindsight is always 20/20.


Lessons learned this time out:

1) The QRP Guys KX single lever paddle is a neat!  I used it the entire time and had no problems. No inordinate amount of sending mistakes and no fatigue. The paddle has a good feel to it and allowed me to send crisp code at varying speeds between 16 - 23 WPM.

2) I need new ear buds. The current ones have served me well the past 4 - 5 years. The right ear bud has developed a scratchiness which is not debilitating; but is definitely annoying.

3) Engage the noise blanker on the KX3 earlier. As I mentioned before, 40 Meters was pretty noisy up there at the park for whatever reason.  Towards the end of my stay there, it dawned upon me to turn on the KX3's noise blanker. It helped, a lot!  I probably wouldn't have made as many QSOs on 40 Meters as I did, without it. Sometimes I get so used to putting the "filter between the ears" through its paces, that I forget the mechanical and electronic aids that are available to me.

4) Trust your gut. The 5 aH SLA died rather quickly at Field Day and then it charged up rather quickly after. That told me right then and there that something wasn't quite right.  So even though I knew it was probably on its last legs; I was still hoping against hope that I was wrong and it was okay. My gut was right, my hopes were ill-founded.

5) This one I already knew, but I will reiterate - always carry back ups!

So even though a battery died on me, and I didn't make as many QSOs as I would have liked and band conditions were in the dumper, it was still a good day. As I wrote to W3BBO in an e-mail - a lousy day at QRP is way better than a good day at work!

I'm hopeful

The weather prognosticators in NJ are forecasting a very wet Friday night into Saturday. The good news is the very heavy rain will be south of my QTH and the forecast for Sunday is looking decent.

That means that my plans for Flight of the Bumblebees remain intact, so far.  I hope to be operating from one of my favorites, Washington Rock State Park in Greenbrook, NJ.  As an added bonus, that is KFF-1635, so if you're a POTA chaser, work me and you'll get credit for that, as well.

Not sure whether I will use the PAR ENDFEDZ or the EARCHI.  I usually stick to 40 and 20 Meters in these sprints, especially now that we're nearing the bottom of the sun spot cycle. The EARCHI would allow me to access 15 Meters; but I'm willing to bet dollars to donuts that the band will be dead, or nearly dead. I'll probably pack the magloop in the car, too and may play with that for a bit.

Hope to work you on Sunday!

Look at these beauties!

I saw these on a Facebook post by William Robert Leschyna, VE3UK.





Air variable butterfly capacitors for magloop antennas that he makes by hand!  Aren't they gorgeous?

Yeah, I know ........ only women are supposed to be gorgeous; but hey, I'm a Ham, a techno-geek, and I think these are works of art!  Just look at and admire the craftsmanship!

Anyway, he offers these for sale (you can contact him via his QRZ e-mail).  They're a bit on the pricey side; but oh man!

Amateur Radio Parity Act

Please take a few moments of your time to contact your respective United States Senators and urge the to support S. 1534, the Amateur Radio Parity Act.  This bill passed through the House of Representatives as H.R 555 and will be going before the Senate for vote.

The bill "allows for effective outdoor Amateur Radio antennas for public service and emergency communications while protecting the prerogative of community associations."  The language of this bill, which represents a mutually acceptable compromise, was agreed to by both the ARRL and the Community Associations Institute, which represents home owners associations.

The ARRL has made this super easy to do.  Just go to https://arrl.rallycongress.net/ctas/urge-us-senate-to-support-amateur-radio-parity-act and hit the "Send Message" button. You will be prompted for your zip code, your name and your street address. An e-mail encouraging passing of this legislation will be sent to both of your state's U.S. Senators.

You need not be a member of the ARRL in order to make use of this service.

Morsum Magnificat news

You might remember a post that I wrote back in April, where I directed you to N7CFO's Download Website where all the copies of Morsum Magnificat were available for download.  At that time, each issue was available as an individual .pdf file.

Since then, N7CFO has made ALL the issues (including the ones that were missing AND the three special issues) available for download in one, big 897 MB zip file.  Even with a good connection, it took close to 20 minutes for the file to download; but I have them all on a thumb drive now.

If you have slow Internet connection, you might want to start downloading some evening before going to bed and let your computer do its thing overnight.

Oh, so bad!

What's so bad?  My fist on my Llaves Cootie key.


After a discussion on Facebook with another Ham about the differences between a single lever paddle and a Cootie, or sideswiper key, I decided to take mine off the shelf. I blew the dust off - just to give you an idea of how long it's been, and hooked it up to the KX3 with the VOX off.  This allows me to use the KX3 as a code practice oscillator on steroids. I hear the side tone, but no RF goes out.

And that was a good thing!  I did not need to record my fist to realize how terrible it was.  After so many years of using paddles, where one side is dits and the other is dahs, my muscle memory wanted to do the same thing with the Cootie.  But you can't.  You have to keep swinging left, right, left right, left, right and just vary the timing for the dits and dahs.

I kept at it for about 15 minutes or so, starting with only making dits and dahs at first (multiples and then alternating) and then sending real characters after. I found "L" the hardest for me to get used to, for some reason. I estimate that after about a week's worth of practice, I should be proficient enough to be able to go on the air for real without embarrassing myself too badly. "So why bother with a sideswiper at all, if it's so hard?", you might be asking yourself? For one, I enjoy the challenge and secondly, I like being able to use a manual key (like a straight key) without the discomfort a straight key causes me.

I really admire those who can switch between paddles, bugs and sideswipers without missing a beat. Those folks are amazing!

From the mail bag

I received a couple of e-mails asking me to post some information - perhaps opinion, would be a better term. In the first, I was asked if I would list, in one spot, the materials that I used to build my magloop - here goes:


Capacitor -  20-240 pf - RF Parts - Part # 73-145-25 - $49
Capacitor Enclosure - PolyCase - Part # WP-33F - $18
6:1 Reduction Drive - Oren Elliot - Part # BD-602 - $18
Coax for main loop - DX Engineering LMR400 - $10
Tripod base - Husky Work Light tripod - $19

The feeder loop was made from spare #14 wire and the feedline was taken from spare RG-8X coax that I had that was just sitting around. The PVC support pieces were purchased from Home Depot - 1/2" schedule 40 PVC. In addition to the tubing (18" sections), I used one 4-way cross piece and three PVC Tees. The total cost for all materials came to less than $125, including the stand.

Nothing against the commercial magloops that are out there that are available for Amateur Radio use. They're all top notch pieces of equipment; and you wouldn't go wrong purchasing any of them. However, there's just something ultimately satisfying about rolling your own and ending up with a specimen that works, really well.

The second e-mail asked for a recommendation for keys for those who are just beginning to use Morse Code.

For the neophyte, I would recommend a straight key to start off.  This will allow you to send Morse at a speed which is most comfortable for a beginner - slow. My favorite straight key, up until recently, have been the Nye Viking Speed-X keys.


They are fully and easily adjustable and the large Navy style knob makes finger placement easy and comfortable.  Using a straight key from the beginning will allow you to concentrate on proper spacing and rhythm of Morse characters. It's harder to let the Code "run away" from you when you're using a straight key as compared to sending with a keyer and paddles, which can be set for a higher speed than a newbie should be using.

Some new Hams dive right into electronic keying, thinking that the almost perfect machine keying will mask their "newness". Actually, I've heard some pretty horrendous CW out there from people using keyers and paddles incorrectly. Yes, the dits and dahs are perfect, but the spacing between characters and words can go all over creation, making copy difficult, if not impossible. IMHO, starting out on a straight key goes a long ways towards teaching proper spacing and weight of the Code.  Once you've mastered that, you can move on to paddles and keyers with confidence in your abilities.

If you want to advance past a straight key; but the thought of electronic Morse Code somehow turns your stomach, there are always bugs and Cootie keys that you can advance to.  A bug, of course, is a semi-automatic key, which allows for the automatic generation of dits and the manual generation of dahs.


Using a bug can be difficult, as they are really meant for code speeds of about 25 WPM or higher. They can be slowed down using various methods, but even so, using a bug is not for the faint of heart. Getting the rhythm and spacing to sound good take practice - a LOT of practice!

Sideswipers or Cootie keys are kind of like a sideways straight key.  These also take a lot of practice to get used to; but not as much as a bug.  The problem with a Cootie or sideswiper is that once you get used to using paddles and a keyer, it's hard to transition back to totally manufactured dits and dahs.  It takes time to get used to the fact that you just don't hold the lever to one side or the other to have a string of dits and dahs come out!


No matter what method you use to send Morse Code, be aware that it will take time and practice to become really proficient.  There are many out there who can switch from a straight key, to a bug, to a Cootie and then to a paddle and keyer and sound fantastic on all of them. If you come across someone like that, you've come across a true Master of the art of Morse Code.  It takes a very log time to get that good!

Finally, whatever way you choose to generate code, buy the best key that you can reasonably afford. Your straight key, bug, paddle or sideswiper will become your vehicle towards sending good Morse Code.  Using a quality tool will go a long way towards adding to your enjoyment of CW.  As a comparison, yes ..... you can drive from New Jersey to California in a beat up ol' jalopy; but the journey is much more pleasurable when you're travelling in a fine luxury automobile.

QRP Guys single lever paddle for the KX series

This lil' guy caught my eye a few months ago, a single lever paddle for the KX3.


I went over to the QRP Guys website, only to see that it was priced at $25. I figured, A) I love single lever paddles and B) "How can you go wrong for 25 bucks?", it's not like it's going to break the bank, and I ordered one.  It came quickly, but today was the first time since it was delivered that I got a chance to sit down and build it. The instruction manual, which you download and print out, gives this kit a difficulty rating of "4" on a scale from 1 to 5, where 1 is "Simple" and 5 is "SMT". To be honest with you, I didn't find it difficult at all, except for one small glitch.

The paddle body itself is made from PC Board material. There are five main pieces - the paddle base, the paddle leaf holder, the left and right contact holders and a support.  All fit together nicely and are tack soldered together to form the paddle body. once you have everything aligned, you re-solder the tacks to make them permanent.

The only problem that I had (with the exception of losing a screw, which went into orbit. It's a good thing I had a serviceable replacement in the junkbox!) was that the paddle support would not fit flush with the paddle base. There's a slot cut for it, but it wouldn't fit.  I had to take out my jeweler's files to make the notch just a tad wider.


The entire process from start to finish took less than two hours and that's with my "check-everything-three-times-before-soldering" paranoia. Again, I did notice that things went easier for me when I took off my glasses and got up close and personal to the work that had to be done. The ol' peepers really aren't what they used to be.




Adjusting the contact spacing was a piece of cake and it was easy to get things just where I like them - almost at touch paddle setting. The manual says that spacing as close as a couple thousandths of an inch is possible and I believe it. I barely have to move the lever in either direction to produce clean, crisp code.

The only thing that I might consider is taking up the manual's suggestion to get a cheap set of feeler gauges to use as stock for a new lever. The one supplied is a little "whippy" in my estimation. A thicker piece of metal would feel more robust. The lever supplied is certainly usable as is; but a stiffer one would just be improving the feel a tiny bit closer to my subjective preferences.  You know how fussy and particular we CW ops get about our keys!

The final step that I took (stupidly, AFTER taking the photos!) was to take a permanent black magic marker, and go over the edges of the circuit board material and to cover over the solder fillets. That made the who assembly look a bit more "finished". A nice touch is that if you own a set of the SideKX side panels and Lexan cover, there are no issues with placing the Lexan cover on your KX3 while the paddle remains attached. It does not get in the way of the cover, whatsoever. Additional bonus - you can still use your favorite paddle(s) while this remains plugged in.  You do not have to remove it in order to use your favorite external paddle.

If you want to have an attachable paddle for your KX3 or KX2, but feel squeamish about parting with the dinero for a set of Elecraft KX3PD or KX2PD attachable iambic paddles, then you might want to look into buying one of these. I think I'm going to enjoy using mine - I do so far!

Another facepalm

When I first introduced the "QRP - When you care to send the very least!" car stickers, I received an e-mail from Bill Unger VE3XT asking if I had any problems sending stickers to Canada.  I replied, "Just send a snail mail indicating the number of stickers you want and the funds, and I'll get them right out."

Sure enough, an\bout a week later, an envelope from Bill showed up in my mail box. I put the requested number of stickers in a return envelope and went to the Post Office and used their handy dandy automated postage kiosk to determine the correct return postage to Canada and tossed the envelope down the "Out of Town" mail chute.

A few weeks went by and I got to wondering if Bill did, in fact, receive them. so this time, I sent him an e-mail asking him if he had received them.

I got a reply that he hadn't; but while being a little concerned, I figured that they call it "snail mail" for a reason and I decided to give it a bit more time. I had planned to wait another week to ten days, and t send another inquiry. If Bill still hadn't received them, I would send more.

On Friday, I received an e-mail from Bill.  He got them!  Huzzah!  What I hadn't anticipated was the photo he attached. Oh, they arrived all in one piece and good shape; but I didn't know that there were that many Hams at the United States Postal Service.  They decided to send the stickers to Bill via longpath!


Jamaica ?? Really !!  I know my chicken scratch printing is pretty awful, but even I can make out that  the envelope is addressed to Thunder Bay, Ontario, Canada. I know there's a Montego Bay in Jamaica ..... is there a Thunder Bay there, too? LOL!

The important thing is that they got there, safe sound and in good condition. To any Ham friends that work for the USPS, this is not a knock on you. I'm sure that one of the automated sorting machines probably messed up and if this had been in your capable, human hands the envelope would have sorted properly and would have reached Canada straight off.

Yesterday, the south Plainfield Amateur Radio Club set up a station at the gazebo at Spring Lake Park, the same park where we set up for Field Day.  The intent was to celebrate and participate in JOTA, the Boy scouts Jamboree On The Air.  Harry, KC2PGK is a Scout Master to one of the troops in town and he invited all the Scout Masters and Troop Leaders to bring by as many Boy and Girl Scouts as possible to get a chance to get behind the microphone and get on the air.

The good news is that NJ2SP managed to work station K2BSA, the official club station of the Boy scouts of America from Jamboree 2017 in Glen Jean, West Virginia.  The bad news is that no local Scouts came out to participate.  We were all disappointed; but I reminded everyone that this is a very tough time of year, as school is out, families are on vacations or otherwise have weekend plans. To make matters worse, we really didn't do the absolute best that we could have done with publicity and communications, so the fault is probably partially ours, too.  As a new club, we're still struggling to find our way and get things like this done the right way. The important thing, is that we're trying!

Bad advice from the Internet

In my most humble opinion, the Internet and social media have been a boon to Amateur Radio. Never before has learning and Elmering become so easy and widespread.  There is sooooo much good information out there on antennas, equipment, operating procedures and practises ...... it almost makes me jealous that we didn't have this back when we were Novices in the "dinosaur days".

But there's a down side, too.  Just as there is a lot of good information out there, there's also stuff that makes me go like this when I read it.


And this happens particularly when it comes to the topic of learning Morse Code. I realize that when it comes to learning, that people are like snowflakes - no two are alike. But I know bad advice when I see it, and there's plenty of it out there.

I think that for the vast majority of people, using gimmicks or visual associations for learning Morse Code characters is a very, very, very bad idea.  I know that the Morse Code is a huge obstacle for some people. Back when I was a teenager of 16 years, I had such tremendous problems learning Morse, that I gave up on it myself for several years. If I had the Internet back then, I probably would have followed some bad advice that would have been offered to make learning Morse Code "easier". Looking back on it, that was exactly my problem, even without having the Internet.  A well meaning person gave me a Morse Code chart - all the letters of the alphabet, and the numbers printed out, alongside their Morse equivalents. It became a crutch.  My brain just couldn't make the audio to visual to brain connection quickly enough; and I gave up.  It was only about 5 years (5 years! 5 wasted years!) later that an instructor gave me the ARRL Morse Code cassette set with the admonition to LISTEN, that I was able to learn the Code successfully.

In the end, using visual associations such as charts or tables, counting dits and dahs, or any kind of mental associations (D = Dog did it)  or other quickie learning gimmick actually slows you down in the long run. Sure, it may have helped one to get to the minimum 5 WPM level quickly, but after that, these methods hang around your neck like the proverbial albatross.  Because once you get to the 10 WPM level, you will reach a plateau - and until you unlearn those bad habits, you won't advance any further. Maybe the best analogy is that the Morse Code characters have to become as automatic to you as hitting the brake pedal on your car when you see the brake lights on the car in front of you come on. You don't think about it, you just do it!

As I eventually learned, the best method to learning the Morse Code is by listening. Not looking ....... listening.  I think the best method is to combine both the Koch and Farnsworth methods.  The Farnsworth method would have the student listen to Morse Code characters sent at a speed of about 13 WPM, but spaced out at a speed of about 5 - 8 WPM.  Using the Koch method in combination with this would be to introduce the similar characters in bunches, at the same time, i.e., first learn, e, i, s, h, 5 first and get comfortable with those before moving on.

But above all, it is important to imprint the sounds in your brain. Anything which can come in between the ear and brain is going to make things much harder once you've reached the point where you've learned the characters and you're training to increase your speed.

In another post, I'll go into some of the resources available for learning Morse.  I haven't looked into these in a while, and I'm certain some good stuff has become available since I last looked.

The S-band transceiver was the primary transceiver used for TV, telemetry, biomedical data, and voice communications from the Lunar surface. It had an output power of  750 mW (QRPp!).  That signal then went to the S-band power amplifier, which boosted the signal to an outstanding "QRO" signal of 18.6 Watts.

Doing some housekeeping

You may have noticed (or not) that the blogroll to the right has shrunken a bit.  I removed a couple of blogs that no longer have valid links (can no longer be reached). I also moved a few blogs that have been inactive for a year or more down to the dormant blogroll.  Anytime that these become active again, I move them back to the top list. I also removed a couple links that no longer had valid URLs; and edited some where the URLs changed.

If you  know of any blogs focusing on QRP, CW or portable ops that are worth following and that I don't have listed, either send an e-mail to w2lj@arrl.net, or leave a comment in the commbox. I'll give them the once over and will add them if they seem like a good fit.

Send an e-mail to ARSBumblebees@gmail.com and be sure to include your first name, call sign, the field location you plan to operate from and your three top choices for a Bee number.

Keep in mind that you are encouraged to participate in the FOBB as a home station - but only Field Stations can have a Bee #.

After you've sent KI6SN your request, be sure to keep an eye on the roster at the link above. That's where you will be able to determine what number you've been assigned.

The rest of the rules can be found at http://arsqrp.blogspot.com/2017/07/announcing-ars-2017-fobb.html

FOBB is, was, and continues to be the best Summer Outdoor QRP event, bar none. It's the equivalent of the Masters, or Wimbledon or Tour de France of the QRP Summer contest season. Get out there, get some sunshine and some breeze in your hair and have fun!

I can hear wings buzzing already!

Back from the Lake

As I type this, massive depression is setting in as the last few hours of my vacation week are coming to a close. Tomorrow, it's back to the Old Grind.

Last week was spent at our customary place at Lake George, NY.  The weather was iffy, with rain and thunderstorms at the beginning and end of the week. Sandwiched in the middle was some good weather.  I didn't head out for my customary QRP session at the top of Mount Prospect until Monday, this time. Usually, I head out there on Sunday and take part in the QRP-ARCI Homebrew Sprint, but this year I was content to spend Sunday doing my best imitation of a couch potato.

When I went up there on Monday, I brought the magloop along and set that up.  Immediately, I knew something was wrong.  I was having a very hard time getting a loud background noise "sweet spot", which indicates a good match.  Removing the top of the capacitor enclosure, it became obvious that if I turned the tuning knob in one direction, all was well. When I tried to tune in the opposite direction, the capacitor shaft would not turn at all.  Argh!  One of the two set screws on the reduction drive had come loose!

And of course, of all the tools that I carry in the Jeep, a complete set of hex wrenches is not included. I put the magloop away in its carrying sack and broke out the Jackite pole, my drive on mast support and the PAR 10/20/40.  I had that up and on the air in a few minutes, but the bands seemed dead. I had no luck calling CQ and I wasn't heard on 17 Meters by J68GD, who was loud, but called CQ in my face when I tried to answer him.  Obviously, this was another instance when propagation wasn't reciprocal.  I went back to 20 Meters and was hunting around when all of a sudden it got very windy. My ARRL mini log books were flying all over the place and the Jackite was doing its best impression of a Hawaiian Hula dancer. I decided to call it quits for the day, and head back to the cabin.  On the way back, I stopped by a small hardware store in Lake George Village and picked up a good hex wrench set.  When I got back to the cabin, once again I removed the top of the capacitor enclosure. The one set screw was tight and was right as rain, but the other needed about a 1/4 turn to get it snug. I gave it an extra bit of torque to make sure it was tight, but not to the point of rounding off the set screw.  Right away, I was able to turn the tuning knob in both directions and see that the capacitor shaft was moving, also. Lesson learned - always have the proper tools close by!

Although I didn't make any contacts, later that night I logged onto the Reverse Beacon Network website and plugged in my call sign to see if I was being heard.  I was!  Good signal to noise reports all up and down the East coast, into the Mid-west and even out as far as Saskatchewan, Canada. I was getting out, I just wasn't getting any takers.

The end of the week turned rainy, damp and chilly.  Thursday afternoon was spent largely in the cabin. Once again I decided to set the loop up in the cabin.  I wasn't hearing all that much, except on 20 Meters, where I was hearing some DX. US1GCU was calling CQ, so I gave Leo a call and got an answer.  To the 599 that I gave him, I got a 579 in return.  A few minutes later, I heard a loud UR4EZ calling CQ.  Sent my call again and was answered immediately. Victor gave me a 579 and I gave him a 599.  Both Ukrainians were very loud.  I was very pleased to receive the 579 reports as I never mentioned to either Leo or Vic that I was running QRP power and that I was using a magloop antenna indoors. And since the unsolicited 579s were received instead of "compulsory" DX 599s, I will take it that I was given RSTs that were honest and somewhat accurate.

Again, this magloop continues to amaze me.  It boggles my mind from time to time that it gets out so well and that I receive the signal reports that I get. Again, this is not an every day antenna; but it sure makes a nice antenna for vacation and portable ops when there are no trees around; or you don't want to mess around with trees on someone else's property.

This morning was the Sussex County Amateur Radio Club's annual Hamfest at the Sussex County Fairgrounds in Augusta, NJ.  I think that without a doubt, this is the largest Hamfest in New Jersey. Luckily, I was able to attend as some years it occurs on the Sunday that we are in Lake George.  I made the trip up to Augusta with Marv K2VHW.  I didn't have plans to buy much of anything. I did come home with some CR2023 button batteries for Harold's LED collar that we use when we take him for walks after it gets dark.  I also came home with a little Radio Shack travel alarm clock that I picked up for $2.  I set it to UTC and put it in my backpack.  It will serve well as my official portable ops logging clock. It is only about 2 X 3 inches and maybe 3/4 of an inch deep, so while it is very small, the display takes up a large part of the front and is easy to read.  There's even a button that you can push to light up the display for reading it in darker conditions.

There were lots of things on tables that I was absolutely salivating over, especially this Brown Brothers straight key / paddle combo.


The gentleman selling it was firm on the price and was more than I was willing to spend. And when it comes right down to it, while I always wanted one of these, I have so many wonderful paddles and straight keys already - how many can you have? And what good would it do to have it just to collect dust on a shelf.  I can't imagine using this primarily instead of my Begali or N2DAN Mercury paddles.  Collecting is nice if you have money to burn, but that's never been the case for me.

Besides, I will be adding one more key to my collection at the end of the month - a W2WK Marconi Straight Key.  I'd rather have one of Bill's straight keys than the Brown Brothers combo, any day.

The Spirit of QRP

Recently, the South Plainfield Amateur Radio Club sent a press release to our two local town newspapers, to let them know how we did on Field Day.  Mind you, we were operating NJ2SP as 3A Battery, which meant we were operating QRP, that is, 5 Watts output on all modes.

We had a total of 544 contacts, 308 of which were made with Morse Code, 230 were made with voice and an additional 6 were made using PSK31.  We made contact with 41 states (we used states in the press release as the general public would be scratching their heads over "sections", and I'm not sure how many sections we worked), and 4 different DX countries - Canada, Bahamas, Puerto Rico, and the US Virgin Islands.

We had our best year ever for SSB contacts, and I attribute this to the fact that Dave KD2FSI finally got Marv K2VHW's tri-band beam tuned up properly and that helped us immensely.  As one of the two CW ops, it warmed my heart to look at the logging computers to see that the phone stations were actually keeping up with the CW stations somewhat. It's no fun to sit at a microphone and announce your call sign over and over, while not being heard by anyone at the other end. It's doubly not fun to be successful behind the key while watching your friends behind the microphone get frustrated because they don't have the proper tools at their disposal.

Which allows me to segue to another, but related topic.  There are many in our QRP community who think that taking advantage of antennas other than wires or verticals is somehow "wrong". To them, QRP is a minimalist thing, only.  QRP power to the simplest of antennas is all they want, or all they need.

As a sub-niche in the QRP world, that's fine.  Go at this any way you want.  But to look down on, or denigrate other QRPers who take advantage of beams and towers, beverage antennas and full wave loops is ludicrous.  To many, including myself, the Spirit of QRP is taking that 5 or 10 Watts of RF power and doing the most you can with it.  If I had acreage, you'd be darn tootin' that I'd have full wave loops up and all the wire that I could manage to hoist into the air.  If my XYL was amenable, and I could afford it (another subject entirely), I'd have a 40 foot tower with a Hexbeam atop it in a heartbeat. Would that make me less of a QRPer?  Certainly not!

Do you disdain those who use coupons to stretch the most they can out of their food budget?  Would you scoff at a person who got creative with left overs in order to not waste food or money?  Do we applaud people who find new and innovative ways to recycle items so as to protect our environment?

I think you can see where I'm going here.  The Spirit of QRP is taking that low power and using the most efficient equipment and antennas that are available to you under your circumstances and having the maximum amount of fun that you can have with it.

End of story.
