Satisfaction

I think, perhaps, it was during Field Day, or at a recent SPARC meeting that our Club President, Bill W2AOF and I got to talking about portable operating and antennas. He told me that he likes to set up his KX3 at the cabin that his family owns in the Pocono Mountains near Lake Wallenpaupack in Pennsylvania.

The problem is that he was not satisfied with his temporary antennas that he had been setting up. For whatever reason, throwing a wire up into a tree seems to be a tricky and time consuming proposition. Since I've never been to his cabin, I'm assuming the deck from where's he's been operating doesn't afford the greatest of antenna situations. There may be a steep drop off of land which makes navigating on the ground tricky, for all I know. In my mind, I imagined trying to get a wire up in a tree while at the same time trying to be careful that I don't roll down a steep hillside. My luck, I'd break an ankle or worse.

Bill is semi-retired and owns his own business now. He's been particularly busy between that and his duties as Assistant Manager of Emergency Operations for a neighboring town next to South Plainfield. As a result of that busy-ness, he and his wife Nancy were headed up to the lake for a few days of much needed R & R.

I was totally unaware of his plans, when an inspiration hit me. I have two magloops, the AlexLoop and my homebrewed one. I can't use them both at the same time, so I texted Bill the day before they were going to leave (unbeknownst to me) and I told him, "I have something for you."

He told me that he was busy that Saturday morning, involved in a food distribution event in the town for which he volunteers, but would be home after 2:00 PM. I waited until he texted me that he was home and took the homebrewed magloop over. He was surprised and delighted, and I was surprised to find out they were leaving for Pennsylvania that very afternoon or evening. Timing could not have been better.

Later that week, he told me he had the loop set up. I had texted him some basic instructions along with some photos that I took from some of the times I had deployed it when I had used it for National Parks On The Air. I guess my instructions were good enough, because later that week he texted me back saying his first two contacts were with Latvia and Croatia on 20 Meters.

So this brings satisfaction on several levels - first, I was able to give away something that was taking up space in the computer room of our house. That made Marianne a bit happy. Second, I was able to give something to a friend that fulfilled a need that he had. Third, the thing that I gave him actually works! I mean, I know it does as I've used it successfully myself for years, but seeing it also work for someone else makes my heart feel glad.

Is a magloop the ideal for this situation? In my old school mind, a dipole or other wire is always the ideal. If and when that becomes impossible or close to impossible, or an even dangerous solution, then the magloop becomes the ideal, especially when it's a situation of just casual operating. As the old sayings go, "Any kind of antenna is better than no antenna." and "Even a bad day of fishing is better than a good day at work."

QRP - When you care to send the very least!

Not exactly what I was hoping for ...

 but I'll take it!

I met with W3BBO for our weekly ragchew on Skype at 3:00 PM. He let me go early so that I could set up for the QRP ARCI Summer Homebrew Sprint. I was going to set up on the big deck they have here where we're staying, but the skies have been overcast and threatening all day, so I set up on the porch instead.

At 4:00 PM I tuned to 20 Meters and I heard quite a few SKCC Weekend Sprinters (WES) all by their frequency and up into the QRP Watering Holes. However, I did not hear one single solitary QRPer calling "CQ QRP" or whatever. Undeterred, I called CQ for a while on 14.062 with no result. I switched over to 40 Meters and that band was pretty dead as a door nail, too.

Rather than call it a day so soon. I decided to go back to 20 Meters, but down the band a bit. Maybe I could catch some DX?  Sure enough I did! I heard F5PLC calling CQ on 14.037 MHz with no takers. I crossed my fingers, took a shot and put out my call. I got an answer immediately. Michel "Mike" was a solid 599 and he gave me a 579.  How could I help but not be 579 when my signal was being picked up by this antenna?

Mike was transmitting with 50 Watts from near Belfort, France which is not too far from the Swiss border.


I think I may have been close to his QTH when I was in France during my second visit to Switzerland in 1994. And looking at his QRZ page, Mike is quite the CW aficionado and a QRPer, too. Look at his KX1 !


After we signed, I decided to go back up to QRP Country to see if I could hear any Summer Homebrew Sprinter's and alas I did not. But I did hear OZ30EU coming in like gangbusters!


Svend was 599 +++, but I was avery weak 329 to him, but as I said up top - I'll take it! Svend was very gracious and patient. He stuck with me when he could have easily resumed calling CQ right over me. He didn't and I sent him an e-mail of thanks, explaining my set up. I just hope that his e-mail address as provided by QRZ.com is current and accurate.

I finally gave up when Marianne joined me on the porch, nudged me and said, "Don't you hear the thunder?" In all honesty, with earbuds in, I did not and I didn't see any flashes either, but maybe I was just concentrating too hard on the KX3 and the DX. I tore down and brought everything in, not desiring to take any chances as minute as they might be. So no Summer Homebrew Sprinters, but France and Denmark running 5 Watts to a magloop. Nice way to start off the week here!

It's getting to be that time of year again

When I have to decide what equipment I'll be taking up to Lake George when we return for our annual trip this summer. Undoubtedly the KX3 and the AlexLoop with be the main components, but I'm thinking of also bring the PAR ENDFEDZ and the arborist throw bag to get some wire in a tree.

The problem is that I really haven't practiced tossing that thing up into the trees enough so that I don't look like some kind of idiot. Maybe this weekend after I get all the other stuff done that needs to be done (and if the weather cooperates), I can make my way over to Cotton Street Park, where I go for FOBB and the Skeeter Hunt. There's a lot of tall trees that would make for great practice.

In the meantime, I know there are some tutorial videos on YouTube that I can watch so that at the very least I look like I know what I'm doing. You'd think that this would be a no-brainer, but I've seen a couple if videos a while back that indicate there are several techniques that the pros use for good success. 

The last thing I want is to look like a rube, and ideally I'd like to get a line up in one shot, if I can. I'm not into attracting curious onlookers. And if I do attract onlookers, I don't want to provide them with reason for hilarious laughter.

All that being said, Sunday July 9th is the QRP-ARCI Summer Homebrew Sprint. This always seems to occur the first Sunday we are there. It may be time for a trip up Mt. Prospect.

The high temp in South Plainfield is expected to be 27F with a bit of a breeze, so it may feel colder. I may set up the magloop and KX3 on the front stoop and participate for a bit. I'll be home alone as the kids and XYL are all out tomorrow doing their own things. A rarity for W2LJ. I wish I had a pair of those fingerless gloves. Maybe I can find a cheap pair at the grocery store tomorrow and take a pair of scissors to the right glove.

Then later in the afternoon, I'll hop downstairs to the shack to see if I can't make a few QSO party QSOs, just to fatten the log up. It's been way too long.

Loopy at the lake

 Marianne and I have headed back up to Lake George, NY for our yearly July sojourn. This year I decided once again to keep it really light in the radio equipment department. I left the full QRP portable backpack at home and brought along just a daypack. This year I have just the KX3, my small lithium battery,  a couple set of earbuds, a backup Bulldog clip key and the Alex Loop.

Since I acquired the Alex Loop from Peter NN9K a couple of years ago, I have not used it enough to be comfortable with it. It works, but I don't know its "ins and outs" very well. I'm not totally sure you can thoroughly know the "ins and outs" of any antenna, as there will always be surprises. By comparison, in the case of wire antennas, I'm a lot more confident in knowing what I can work and what I cannot work. I am hoping to become more familiar with the Alex Loop this week.

I tried listening for some ops in the QRP-ARCI Homebrew Sprint yesterday afternoon. I was disappointed as I only was able to hear some SKCC Weekend Sprinters. Even though I heard them, I didn't work any as I haven't brought a straight key with me. It doesn't seem quite kosher to participate in an SKCC event with keyer and paddles.

This morning, I attempted to work Mike KC2EGL and John K3WWP as NY3EC at the USS Requin in Pittsburgh. I set up HamAlert to let me know whenever they were spotted by RBN or the Cluster. I did not hear them on 20 Meters when they were spotted there, and I did not hear them on 40 Meters when they were spotted there. I was able to make them out on 30 Meters, however. They were at ESP levels, and I was able to hear the stations they were working, and was able to figure out that it was Mike at the key. I patiently waited for their signal strength to rise. Eventually they got up to about a 449 and I gave a call. I made contact, but it's a busted QSO as I'm pretty sure that Mike was copying me as W2BJ. I did get a 339 report, though. Then QSB reared its ugly head and they disappeared, even though reports from HamAlert confirmed they were still on the band. Maybe I should follow K3WWP's advice and invest in a PX3 panadapter. I don't care for waterfalls, though - call me an old fogey. I was, am and always will be a dial twiddler - and cheap! The Ham Alert app is a freebie!

So then I did a little experimenting by calling CQ and looking at Reverse Beacon Network reports on the various bands. It seems the Alex Loop is best heard on 40 and 30 Meters. Those two bands gave me the best db above Noise Level reports. 

So later in the afternoon, I sat down to try and work NY3EC again, as I was still getting reports that they were on the air. No matter what band they were on, this time I couldn't hear them. However, while tuning across 20 Meters, I heard RW3XW calling CQ at the bottom of the band. He was strong, but there was a lot of QSB but I decided to give the ol' roulette wheel a spin and give it a shot. My recent experiment be darned, telling me that my RBN reports on 20 Meters are not the best - I gave it the ol" college try.

Success! I got him in the log on the second try. Shaking my head, I was not able to work Pittsburgh on any band, which is a small hop away - but I was able to work Russia which is several thousand miles away on a band where the loop doesn't give me my best results. If I live to be a hundred, I'll never figure propagation out.

I came into our cabin to log my contact on AC Log only to get a bit of a scare. This old Lenovo T430 came to life, only with no mouse cursor pointer! The finger pad and the little "mouse" controller button in the middle of the keyboard were both inoperative, Great - just what I really need - a bum computer for the rest of the week and of course, I did not bring along an external mouse.

I'm not what you would call "IT savvy" but I know enough about using the keyboard keys to navigate around. Soon I was able to get to the Control Panel to try and see if I could get things working again. The drivers were up to date and re-loading them didn't help any. The Device Manager was telling me that the drivers would not upload on boot up  Why? I have no idea.. I did remember that when I shut the laptop off last night, it did a Windows Update. Something funky must have happened then and there.  I managed to navigate over to the recovery area. I did not do a full blown backdate, but I was able to do a recovery and a re-boot which got the mouse pointer working again.

Whew - computers ARE black magic - especially when you're not an IT whiz. I was lucky this time, but now I'm strongly considering an upgrade in the near future. This machine is too old to run Windows 10 reliably and Windows 8 support stops sometime soon.

This is too good not to share

Words posted by Wayne Burdick N6KR to the Elecraft KX email reflector. They are too good not to share:

"On second thought, I think I'll take the stairs."

by Wayne Burdick, N6KR


I have a friend about my age who got into amateur radio only a few years ago. Like many of us, he was enthusiastic about the technology. Intrigued with DX.

I showed him my station; we talked endlessly about gear. Later, I helped him put up a simple wire antenna.

Then, when his license arrived, he dove straight into FT8 and didn't look back. Within days, he'd worked all states, then DXCC. He'd bag a few rare ones over a light lunch, then pat his laptop on the back and congratulate his software app for its near-mythical ability to extract weak signals out of noise.

Within weeks, he'd mastered everything there was to know about this glorious new hobby.

Point. Click.

In this new world order, those of us who took the longer, slower path to ionospheric enlightenment -- and who still occasionally enjoy making waves by hand -- often fail to explain why.

I had failed to explain it to my friend. Even as hints of his boredom crept in, creating an opening, the best argument I'd made for trying CW was that he could do it without a computer. Coming in a weak second was the notion that CW was the original digital mode. For obvious reasons, I didn't bother with the classic argument about CW's signal-to-noise advantage over SSB.

I had all but given up.

Then, in a moment of delayed clarity, I decided on a different approach. I invited him to a weekday brunch. A bit of an escape. He willingly took the bait.

On the appointed day, arriving at his workplace, I bypassed the lobby's glistening elevators and climbed the four flights of stairs to his office. I insisted we take the stairs down, too.

"Why?" he asked. "And how'd you get up here so fast?"

I pointed out that I always chose stairs, when possible. That's why I wasn't out of breath. We hustled down, jockeying for position, and emerged on the ground floor invigorated by the effort.

"So, where are we going?" he asked. We'd been to every overrated twenty-dollar burger venue at least twice.

I replied that we'd be going someplace we'd never tried. My kitchen.

When we arrived, I put him to work chopping onions and broccoli and squeezing oranges while I whipped eggs into a froth and grated Swiss cheese. We ate our omelettes outside, in full sun and a cool breeze.

"What's for dessert?" he asked. "Isn't there a frozen yogurt place a two-minute drive from here?"

I had something else in mind. Back in the kitchen, I handed him a water bottle, then slipped on a small pack I'd prepared earlier.

We walked a mile or so through my neighborhood, admiring the houses' varied architecture, ending up (as planned) at a local park festooned with blackberry bushes. The most accessible branches had been picked clean, but with teamwork and persistence we were able to gather several large handfuls of fat, ripe berries, which we devoured on the spot.

We'd been poked and scratched but didn't care.

"Doesn't brunch usually end with champagne?" he wondered aloud, admiring his wounds.

Not this time. I pulled out two bottles of craft beer that I'd obtained from a neighbor in trade for repairing his ancient home stereo. Carlos had spent years crafting an American pilsner to die for, sweating every detail, including iconic, hand-painted labels.

My friend accepted the bottle, then tried in vain to remove the cap. Not a twist-off.

"Opener?" he said.

I handed him a small pocket knife, an antique without extra blades. He soon discovered it could not be used to remove the cap directly. He looked at me with a bemused expression, no doubt wondering what I had up my sleeve this time.

I pointed out that we were surrounded by white oaks, a species known for its hard wood. He got the message, smiled, and began hunting. Within seconds he'd collected a small fallen branch. I watched as he used the knife to fashion a few inches of it into a passable bottle opener. We popped the caps, toasted his new-found skill, and traded stories of misspent youth.

"Oh, one more thing," I said.

I pulled a KX2 out of my pack, along with two lengths of wire. Of course he knew everything there was to know about Elecraft, and me, so he wasn't surprised when I also pulled out the rig's attachable keyer paddle. We threw one wire in the closest tree and laid the other on the ground.

He didn't have to ask whether I'd brought a laptop.

We listened to CW signals up and down 20 meters, open to Europe at the time. As he tuned in each station, I copied for him using pencil and paper. He'd learned Morse code, but only at very slow speeds.

After making a contact, I set the internal keyer speed to 10 words per minute and dialed power output to zero, for practice purposes, then showed him how to use the paddle. He smiled as he got the hang of it. Sending the full alphabet was a challenge, but he got there. The KX2 decoded and displayed his letters, providing confirmation.

We'd blown through his allotted lunch break by a factor of three, so it was time to go. We coiled up the antenna wires, packed up, and walked back. As I drove him back to his employer, we made plans to get together again for a weekend hike.

I could have just dropped him off, but we went back into the lobby together. Out of habit, he stopped in front of the elevator. We watched the illuminated floor numbers flash: digital and predictable eye-candy.

"OK," he said. "I get it. This CW thing. It's slow, doesn't always work, and takes years of practice."

"Like hunting for your own food, or carving your own tools," I added.

"Or cooking from scratch. Or brewing your own beer. Or building your own radio. But you use more of your senses. Not just your eyes, but your ears. Your sense of touch."

I nodded. Listening; feeling. That was the radio I'd grown up with.

"Of course it's harder to work DX with CW than with FT8," I reminded him, playing devil's advocate.

"Is that what matters, though?" he asked, with a sideways glance.

A longer discussion for another day.

"Your call," I said.

He gripped my shoulder and smiled, then aimed a forefinger toward the elevator's glowing, ivory colored UP button, gilded in polished brass.

The path most taken. The easy way.

Point. Click.

"On second thought," he said, "I'll take the stairs."


*************************************************************

Geez, not only can this guy design superb radios, he can write really darn well, too!

On a personal note, I operated in the QRP ARCI Homebrew Sprint this afternoon. While most would not consider my KX3 to be a kit radio, it was, in as much as a KX3 can be considered a kit - it was not factory built - so ...... whatever.

Anyway, I used the AlexLoop. We are up here at Lake George. I also brought the Buddistick along in a last second impulse move as I was packing the car. Yeah ...... I brought the whips, the coil, the base ..... and no coax. So the AlexLoop it is for the week.

I made 6 QSOs. Not great, but actually more than I expected. There didn't seem to be a ton of activity that I was hearing. I was hearing more SKCC Weekend Sprinters than I was hearing QRP stations, but I'm glad that I got what I got. The AlexLoop tuned pretty easily to a 1.2:1 or better SWR on both 20 and 40 Meters. I made five contacts on 40 and one on 20 Meters.

According to RBN, I was being heard pretty decently when I called CQ.


It's a decent antenna .... I'll give it that. I'd still rather have a full sized dipole or even a shortened end fed wire, but it met my expectations. I wanted to travel light with out a lot of "stuff" and I want to be able to set up and take down quickly. I didn't want to ask permission to toss a wire into a tree, either.  It is what it is. I'll play around with it some more. Maybe there's a few surprises in store.

AlexLoop


This is what I sold the two keys for - an AlexLoop. I bought it from Peter NN9K for a very good price. My first impression is that it's not all that different from my home brewed loop, with one big exception - I can tune the 15 Meter band. Listening to P40L on 15 Meters, I was able to tune the SWR down to 1.5 to 1. I was not able to do that with the home brewed loop.

The home brewed loop is a bit easier to tune with the 6:1 gear reduction drive that I put on it. I will have to get used to how sharp the AlexLoop's tuning is. Just a slight touch will take you from an SWR of 25:1 all the way down to 1.5:1. If Alex could pack a reduction drive into that small box, he'd really have a winner.

I wanted this loop with the future in mind, I bought it for the long haul. Yes, there are times when portable ops will demand using it - in parks where wires are not allowed in trees, for example. But I'm thinking about some years from now. Marianne has mentioned moving if and when we ever retire. There may come a day when I'll be leaving in Senior housing or perhaps a condo or townhouse with an HOA. If that ever happens, there may come a day when this AlexLoop could be the difference between being able to operate or being off the air completely.

Fishing at the Lake

When we come up to Lake George for our annual Summer respite, we notice that a lot of folks come up here for the fishing.  Throughout the day, you see people going to their boats; or coming back from their boats, with rods, reels, tackle boxes and other sundry items in hand.

I like to fish while I'm up here, too. My kind of fishing is different however. Instead of plying the waters of the lake, I ply the layers of the ionosphere. Instead of looking for blue gills, bass, carp and sunfish, I look for call signs. In a way, the two activities are a lot alike.

Instead of rod and reel, my equipment is my KX3 and my home brewed magloop.  I could set up an EFHW or perhaps the Buddistick, but the magloop offers rapid set up and take down while maintaining relative stealth. I try to stay in the good graces of our host here, and don't wish to do anything that he might deem as "not permissible".  Throwing a wire into a tree would definitely be pushing the envelope, all though I have done that in the past. The owner has never complained, but some of our fellow cabin dwellers can be a bit "catty" if you will, at times. Why press your luck if you don't have to?




I got on both 20 and 40 Meters yesterday. Activity wasn't the greatest; but I did make some contacts. I worked a W8/G station that I thought might be visiting the States on holiday. He was calling CQ with no takers and I just wanted to assure him that his signal was loud, and was getting out. Turns out he was in fact, in England, in Newcastle. But he was remoting through a station in Michigan via the internet. Sigh - DX that doesn't count.

I switched to 40 Meters and worked several CW Ops that were participating in the 1900 hour CWT, one of their weekly CW Sprints. I worked four stations, all in Virginia. For whatever reason, I seemed to have a pipeline to VA. I worked all on the first try - a testament to their antennas and ears - but also a testament to the magloop. It works, and pretty well at that.

Then I heard my buddy W3BBO working K3TF.  Bob was a solid 559/569 with some QSB. I waited for their QSO to end. Bob said he had to run at the end of his conversation with K3TF. He really did have to QRT! I called him a couple of times with no joy. A subsequent e-mail revealed that Bob had been told that dinner was ready, so that was that. Maybe another day.

Getting back to the analogy of fishing and Ham Radio. I have often commented on how the two are so similar. They both involve skill, smarts, knowing your equipment, but most of all, perseverance, especially for QRPers. If all you know is QRO, and then switch to QRP, you have to switch your mindset as well as your power setting.

Patience is not only a virtue, it is a necessity if you decide to become a dedicated QRPer. The contacts will come, but it will definitely be different than making them with brute force. You'll need to intimately understand propagation, timing, your equipment and yourself. And most of all, you'll need to understand the importance of listening and how that plays into the scheme of things.

Yeah, it's way easier to make those contacts with 100, 500 or 1,500 Watts. But IMHO, at least, it's nowhere near as satisfying.  When you get to the point where you can bust a pileup or make that contact with Japan or Australia the first time you try with 5 Watts, that's Ham Radio heaven.

QRP-ARCI and contests

It would appear that QRP-ARCI is back in the contest business. After advertising for a Contest Manager, QRP-ARCI President Preston Douglas WJ2V announced last week that the position had been filled.

While there is still no dedicated calendar of events on the QRP-ARCI Webpage, an announcement did appear for the Hoot Owl shootout, which was held last evening. This really was a Sprint, in the truest sense of the word, lasting only an hour.

I desperately wanted to join in on the fun, but yard work consumed practically the entire day for me and I was asleep by the time the starting bell rang. You know ....... it's funny. In my mind I still feel like I'm in my 20s. My body, however, just can't do all the stuff it used to. What took me almost the entire day yesterday, I probably could have knocked out in 3 or 4 hours when I wore a younger man's clothes.

I guess that until QRP-ARCI re-institutes a Contest Calendar on the Webpage, the best thing to do is to keep checking for announcements or keep an eye on the WA7BNM contest calendar. Also, http://qrpcontest.com/ is a superb resource.

I did manage to set up the KX3 and the magloop Sunday afternoon at the patio table for a couple of hours. 20 Meters was filled with WPX Contest stations, and I worked a few just to make some contacts. I heard one pair of stations on 30 Meters having a rag chew. Calling CQ on both 30 and 40 Meters went for naught.

While I have, and can make some remarkable contacts with the magloop, I still feel that it is a compromise. It seems to be best suited for situations when there's nothing else that can be used or deployed. In instances where there are no trees from which to hang a wire, or if you're in an HOA situation where max stealth is of utmost importance, the magloop WILL keep you on the air. Just don't expect to make the same amount of contacts that you are used to, using something more "conventional".

Before anyone gets their hackles up that I'm bashing magloops, this is of course IMHO and YMMV.

Upcoming "stuff"

Summer is fast approaching with Memorial Day weekend coming next weekend, here in the US of A. While the day itself has solemn reverence for remembering those who made the Ultimate Sacrifice in service to our country, the weekend also serves as the "unofficial" beginning of Summer.

There's lots to do in the upcoming weeks ahead, and a lot of that involves getting ready for Field Day. I have to get my posterior over to Home Depot to purchase 260 feet of wire for the 160 Meter dipole that I want to build.  Before I do that, I need to get over to Spring Lake Park with a tape measure to see if this is even going to be feasible. No sense of building a 160 Meter dipole of the trees aren't approximately where I need them to be in order to support it.

I also meed to get our Field Day posters finished so that our club members can get them distributed. Filling in that big blank box won't be difficult - getting membership to agree what we want to put there might be.

Sunday, June 9th is the 3rd Annual Cookie Crumble Contest. Huzzah! I have NOTHING scheduled for that Sunday this year. Our normal soup kitchen duty is being performed by another group next month, so the day is free for me and I intend to keep it that way.  I am hoping to set up from Cotton Street Park in town or maybe even Washington Rock again. Both parks have very tall tress in which to hoist up my PAR ENDFEDZ.  I also need to get over to either WalMart or Target for a new bicycle pump. I had mentioned in my post about SPARC's Special Event station that I couldn't use the antenna launcher. It turned out the pressure leak that I was experiencing was because of a hole somewhere in the pump hose. Later on that afternoon, I tried pumping the launcher with a pump the Vadney brothers brought and it worked just fine. It was NOT a leaky Schraeder valve like I had originally suspected.

It's going to be very weird operating these QRP events this year without running into WA8REI, N8XX or N2CX. Those were three call signs that I could usually bank on in QRP events. They will be sorely missed.

Yesterday was a very warm day, so I got the patio furniture cleaned up for the season. Hopefully, that will allow me some chances for outdoor operating this Summer when the weather permits. I'd like to do a lot more experimenting with the magloop to become even more familiar with its "ins and outs". I've used it quite enough to know it's a viable alternative to my permanent antennas; but I need to spend more time with it to become so familiar with it that I know it "like the back of my hand".

I also need to get the Skeeter Hunt Webpage updated for this year; as well as the Skeeter Hunt page of this blog - they pretty much mirror each other.

Wow! That's a lot of stuff to do in and amongst the other "normal" stuff that I have to do every week. It's a good thing that THIS kind of stuff is stuff I enjoy doing!

It was a good night last night.

As it slowly turns to Spring and warmer weather in NJ, it has become relatively comfortable once again, in the W2LJ basement shack. I can go down there for extended periods of time without freezing, as the ambient temps have returned to the 60s.

Last night, 40 Meters was positively jumping! And it turned out to he a rich Fox hunting environment. I was able to work both Jim N0UR and Wayne N4FP within the first 15 minutes of the hunt. The Propagation Princess smiled on me last night, and THAT hasn't happened in a very long time. It felt good. There were so many missed pelts this past Winter season that I was beginning to doubt my equipment, my antennas and my skills - each at one time or another.

Rather than run upstairs, I put some more time into my DSO138 Oscilloscope kit. I started it on Sunday and I've been doing a little bit every day. So far, I've gotten all the resistors, diodes, switches and RF chokes in. If I get home early enough from tonight's South Plainfield Amateur Radio Club meeting, I'll get the capacitors in.

After that, there's not much more to it. I should be able to complete it by the end of the weekend, if all goes well. After that, I think either my 4 States Ozark Patrol receiver, or my 40 Meter QCX kit will be next.

Oh, and by the way, that Mustel G600 microscope came in mighty handy last night. One of the components soldered into the DSO138 circuit board last night was a mini USB connector jack. The pins on that thing are entirely way too tiny and close together. I thought that there was no way I was going to be able to get that thing soldered in without creating one or more solder bridges. After I finished making the last solder joint, I brought out the Mustel and gave the solder pads a good look at ultra high magnification. No bridges!

You may be thinking that the kit building season is traditionally Winter. Not for me. I try to limit my time down in the basement when it's uber cold. Not only is it uncomfortable; but it's bad for the arthritis I have in my hands and my ankles. When I want to operate in the Winter, I either turn on a space heater down there; or I resort to operating from the living room using my magloop. And that's not a bad alternative, actually. It's definitely not as nice as using my outdoor antennas. However, if someday Marianne and I decide to sell the house when we retire, and we end up in some place that doesn't allow outside antennas - the magloop will provide a suitable, stealthy solution. It would not be the death knell of Amateur Radio for me.

It warmed up yesterday

and the basement shack was a balmy 60 F (15 C), but I decided to give the 40 Meter QRP Fox Hunt a whirl with the magloop, anyway.  I was able to locate Wayne N4FP in Florida rather easily and worked him without a problem. Physically rotating the loop to where I could hear him the loudest, helped tremendously.

Drew K9CW in Illinois was a different story. He was weak, VERY weak, no matter which way I oriented the loop.  But since I had discovered where he was hiding, I decided to run to the basement shack to see if I could hear him any better there.

Using the Butternut HF9V,  almost as soon as I sat down, I caught him on a QSB peak and completed the exchange for the second pelt. After that, he faded away and I was able to hear him no better than on the loop. So I cannot conclusively say that the HF9V outperformed the magloop in this case. I just may have been fortunate to have caught him at just the right time with the HF9V. For all I know, he might have come up just as loudly on the loop. There was no way I was able to make a direct A to B comparison.

One thing I will say, though ....... the loop is much easier to tune now. I took one of the sidereal drive "extenders" from my telescope and fit it onto the shaft of the tuning capacitor of the loop. Before I just had a plain ol' vanilla knob. The "extender" is long enough to remove any hand capacitance effect that my body previously presented, throwing off the setting once I removed my hand. Now I can tune for loudest background noise, and lowest SWR and nothing changes when I remove myself from the equation.

Before


After


I was pleasantly surprised at what a difference this extension proved to make.

Plans derailed by chores and the weather.

My melting solder plans for this long weekend became derailed by other chores and the weather. By the time chores and other obligations were finished, Saturday and Sunday evaporated, leaving only Monday for my build day.

However, the temperatures dropped as predicted on Sunday and yesterday's high temperature was only 14F (-10C) and that was only for a very brief period of time. Most of the day was in single Fahrenheit digits. That meant my basement shack was at a crisp 56F (13C) which was too cool for these arthritic hands and fingers to deal with.  I did get a few minutes on Saturday to inventory and organize the components of the kit I am going to work on, though. That was some progress, at least.

While it supposed to warm up today, it will be cold again this evening. I've decided that for the 40 Meter QRP Fox Hunt tonight, I will set up on the dining room table and will use the mag loop. I've done that one time before during the last Winter season and had success. We'll see how it goes tonight.

I played hooky

For those readers who are not from the USA - we have a saying here. When you're a kid, and you don't go to school when you're supposed to, but you go off and do something else that you would rather do - it's called "playing hooky".

I played hooky in more ways than one last week. First off, it was our yearly family pilgrimage to Lake George, NY, so I was on vacation and was "playing hooky" from work. At least it was an excused absence!

Secondly, I did bring the radio gear along; but I have to confess I did not use it much at all. This vacation was markedly different from the past ones. With Joseph and Cara being teenagers now, my time was not spent trying to keep them entertained. They are capable of doing that for themselves now. So I spent my time mostly "vegging", and "playing hooky" from radio, and just about everything else! . I listened to music, enjoyed the view and the fresh mountain air and napped - a lot! It was fantastic. If I felt like doing something, I did it. If I didn't feel like doing anything - I didn't. I was a real lazy bones all week. I can't remember the least time that I had the opportunity to do nothing - and boy, did it feel great!

I did break out the gear on Tuesday and Wednesday.  We had some thunderstorms come through the area on Tuesday morning; but it cleared out and was bright and sunny in the afternoon. Unfortunately, the bands were dead in the afternoon. I worked my bud, Bob W3BBO on 40 Meters, but it was a real shorty QSO. We gave each other 339 reports. he was using his new to him HW-9 and it sounded good. We were both too weak to carry on a QSO of any length or substance, though.

Later as it got closer towards evening, 20 Meters started to open. I began to hear several loud DX stations from Portugal and England and Russia and the Ukraine. I managed to snare UX1RX that evening.  5 Watts from Upstate NY to the Ukraine with a magloop - not bad!


As an aside, two of my cabin neighbors were curious as to what I was doing and what I was using. I had the chance to explain all about Amateur Radio and QRP. Both were fascinated when I told them it was possible to work stations around the world using less power than a nightlight. So now, every time the one cabin neighbor sees me, he calls out "CQ CQ".

Knowing that the bands were dead during the day and not open until the evening was kind of an inconvenience and a disappointment.  Just as the bands were opening, it was usually time to make dinner, or go out and eat and spend some family time together. But that's what a family vacation is all about and I didn't want playing radio to interfere with or spoil those opportunities.  As my children are growing older and becoming college age, I know I won't get many more vacation opportunities like this.  They'll have their own lives to deal with and family vacations where we're all together will become more and more scarce.

Radio can wait - family comes first. Besides, Dad will have his opportunities to play in both the FOBB and Skeeter Hunt, which are coming up soon!

Bad news / good news

There always seems to be a silver lining.

Wednesday evening, after work, I attended a CERT Class on the new Code Blue initiative in New Jersey that calls for opening "Warming Centers" for the homeless when weather conditions dictate the need. After class I went to the parking lot, got in my car, started it up and I noticed the little tire warning light came on. This happens from time to time when one of my tires loses pressure - it lets me know I have to add air to get the pressure back up.

This was not that.  This time as I put the car in gear and started to pull away from my parking spot, I heard that distinctive "whump, whump, whump" sound that immediately sent the message to my brain - flat tire!

I pulled to the front of the County Fire Academy building, pulled into an empty slot and got out. Sure enough, the rear driver side tire was flat.  This was no leak, this was a full out breach!  The magical air had fled the friendly confines of the tire.

I got out the jack from the back and after a few minutes, figured out how to get it apart and working. The lug wrench part of the jack doubled as the crank for the scissor jack.  Of course there were no instructions, other than a few vague pictures, and since I'm not the sharpest tool in the shed, it took me a while to realize that I had to crank the jack a few turns with my fingers in order to let the handle loosen up so that I could pull it away from the jack body and use it.

A fireman who was there taking a course helped me by making sure the jack was positioned correctly under the part of the car that is reinforced to handle being lifted. Soon he had to go inside, so I was on my own.  This is not the first time that I've been to this rodeo. I've changed my share of flats before, but believe it or not, this was the first time I've ever had to do it at night. For whatever reason (I guess that it's harder to see what you're doing when it's dark) that increases the difficulty factor X10.

Got the flat off, and as I'm sitting on the ground, putting the donut (el cheap-o spare tire that they give you) on, it starts to rain.  No, make that, it starts to pour.  So by the time I got finished, I was soaked. My glasses were wet from the rain and the humidity and I had nothing dry to wipe them on. All my clothes, my jacket, everything was water logged. I wiped them off with my fingers the best I could and made it home, slowly and safely.

Yesterday morning, after I dropped the kids off at the school bus stop, I headed to my local Goodyear Tire Center, which is about 2 miles down the road. I explained what happened and the Service Manager said he needed to go out to check the tire size. When he came back in he said, "I have good news and bad news. You need four new tires, not one. They're all worn to the point where you need new tires. I don't have them in stock, but I can get them here for 2:00 PM, so we can get this done for you today". What are you going to do? The car needs maintenance to keep it running, so I agreed. I knew that this was probably going to be the case in advance, as the tires are 4 years old and have over 50,000 miles on them.

I had planned to take only the morning off; but ended up burning a vacation day, as it didn't make any sense to go into work for only an hour or two. The good news in all of this was that while I kept myself occupied at home with various chores while I waited for the tires to arrive, I also got the opportunity to set up the KX3 on the dining room table, alongside the magloop.

And, on the first try, I was able to snare John Laney K4BAI who was signing as PJ4/K4BAI on 20 Meters. John must have been down on Bonaire for the ARRL DX Contest. It still amazes me that my 5 Watts from my dining room table was able to traverse all the way to just about South America using an indoor compromise antenna not 3 feet away from me! And if it works for me - then there's no reason on Earth that a magloop can't be a viable solution to those who have to live under situations where antennas are not allowed or are severely discouraged.


That definitely made the day much. much better! Even later, as I was forking over the $$$ for the tires, that DX QSO brightened the whole day.

"Pardon me .......

........ but what exactly are you doing?"

That was question from another person here at work who passed by the picnic table where I was set up at lunchtime.  This time, however, the person knew what Amateur Radio was when I mentioned it. She asked me if I had contacted anyone, and I was able to tell her, "Yes. Hungary and Italy. Both contacted using less power than it takes to light up your average nightlight."

She seemed duly impressed, and I was able to give "The Schpiel" once again.

The stations I worked today on 20 Meters were HG500L, in Hungary. A special event station commemorating Martin Luther and his 95 Thesis - my Protestant friends will be celebrating the 500th anniversary of the Reformation next week.

The other station I worked was IK6FWJ, Alessandro in Corridonia, Italy Al was running 5 Watts, too and he was loud! Definitely 599 and perhaps some over. it was nice to have a 2X QRP QSO - haven't had one outside of a sprint in a while.

The magloop continues to work and surprise me.

More loopiness

Another sunny day in NJ, so that meant another lunchtime QRP session.  I decided to stay put on 20 Meters for a change. I did a bit of CQing as well as a bit of hunting.  I stayed near the QRP area and heard many stations working a SOTAteer.  I heard the chasers, but not the activator.  I twiddled the dial and went up a bit to hear a very loud OM3KAP in the Slovak Republic calling CQ at around 14.063 MHz.

So I answered.

And I was heard!  But then, when the guy on the other end has antennas like this, how can you NOT be heard?


Miro was conducting a test between two yagi systems for the upcoming contest season. He wanted to know if I was able to detect a marked difference between the two.  I wasn't.  He was a solid 579-599 on both, depending on QSB.  Maybe a younger sprout with better ears could have detected a difference -  but I couldn't.  What I should have done was to ask him to conduct the test a second time, while I relied on the S Meter for an indication. But as they say, hindsight is 20/20 and my brain didn't think of that in real time. This is how he was being heard around the world:


Pretty good, eh?  But then, with all that aluminum in the air, I'd be disappointed if I weren't getting RBN reports that looked like that.  I didn't tell Miro that I was running 5 Watts to a magloop.  After I gave him the report he was looking for, we signed.  It was more than your typical DX "5NN TU" QSO, but not quite a rag chew.  I was happy, though, to snag a bit more of DX.


After OM3KAP, I went down to 14.0595 MHz, which was clear, and called CQ for a bit. I was answered by Mike KA5VZE in Tulsa, OK, who was also running 5 Watts.  Mike gave me a 539 and I gave him a 569; but then things went downhill.  Fading kicked in like nobody's business and we both dropped out on each other.  Oh, what could have been!  A potentially nice lunchtime rag chew kicked mercilessly in the behind by Old Man QSB. We heard each well enough for that final 73 and call sign exchange and the final, final "dit dit". 


Curse you, QSB!

Learning lessons

Today is a sunny and warm day in New Jersey, with a lunchtime temperature of about 66F (19C). This made it a good day for some outside QRP, as the sun made it feel a bit warmer than it actually was, thus providing a comfortable operating experience. The fact that the leaves on nearby trees are changing and are very colorful didn't hurt, either!


I set the station and magloop up in all of about 5 minutes. I seem to be getting better at this. 20 Meters was alive with some activity, but not overly crowded.  I worked Josef at DL0IL in Germany, and then a little later Alexei who seems to be on holiday in the Canary Islands EA8/UA4WW.  Both were decently loud here. I got a 559 from Josef and a 579 from Alexei, so they both seemed to be "honest" RSTs, as opposed to "cookie cutter" 599s.

I heard a French station around the 20 Meter QRP watering hole, but I couldn't quite make out the call.  He was also decently loud here, perhaps even louder than DL0IL and EA8/UA4WW. However, his fist was shaky, and his callsign was extremely hard to make out. F6VAT, or something like that? RBN showed him as F63AT, but that's not a valid call, either. Anyway, it mattered not, for as loud as he was, I wasn't able to get him to hear me, even after trying 4 or 5 times. So much for reciprocal propagation, eh?

So as I gain experience with the magloop, what am I learning?  This is all subjective as I have no empirical data to back me up, but I would say (IMHO):

1) Magloops work, as improbable as that may seem (to me, anyway - still seems weird to me).
2) They seem to work as well, if not better, than compromise verticals, such as the Buddistick or a Hamstick.
3) I have no way of proving this right now; but my hunch would be an EFHW in a tree would perform better. This would be an interesting experiment, to see if I could set them up side by side, for at least a listening comparison.
4) It would seem to me that a permanent "home station" antenna such as a dipole or full sized vertical would have a better performance edge.  This would seem to be only common sense, given the size and efficiency of these antennas.

So when is a small magloop antenna a viable solution?

1) When you are portable, and you are pressed for time and require a very quick set up and tear down.
2) When you are bound by an HOA or other agreement that does not allow for outdoor antennas at your home QTH.
3) When you are operating portable and using trees is out of the question because A) there are none, or B) it is prohibited.
4) When you are operating portable away from your vehicle, thus losing a very effective ground plane for a compromise vertical.
5) When it's all you've got!

My magloop will continue to remain as one arrow in my antenna quiver. I doubt I would ever rely on it, entirely, in an outdoor Sprint such as FOBB or the Skeeter Hunt, although it might be interesting to give that a try, some day.  I think I'm going to have to pull out my WSPRlite and do some more testing, in the mean time.

Phooey!

Today may well be the "Last Rose of Summer" until Indian Summer arrives, if indeed we get one this year.  It was partly cloudy and warm - near 80F (26C). Over the next few days, the temperatures are supposed to drop and bring weather that is more normal for Autumn.

I was hoping to work W3BBO for a lunch time rag chew.  I thought 40 Meters would do us in good stead; but looking at my RBN spots. Bob, who lives in Erie, PA, may have well been in the skip zone.


I called him a few times without an answer and then called CQ a few times, hoping he would look me up on RBN and try to answer me.  An after action e-mail confirmed that's exactly what he did, but he didn't hear me and if he tried calling me, I didn't hear him. Humbug.

I went up to 30 Meters after a while and didn't hear much there. 20 Meters was way busier, and in the time I had left, I managed to get both DR5E and ON4UN in the log.  Quickie DX QSOs rather than the rag chew I was looking for; but it's better than being skunked.

From the admittedly small sample of times I have used the magloop. compared to the multiple times I have used either the Buddistick or Hamsticks on the Jeep - they seem to be about equal performers in a very preliminary estimation.  It's hard to know for sure, though. I used the Buddistick and Hamsticks when the sunspot cycle was much more favorable. Having success with the magloop now makes me wonder how much better it might have performed when solar conditions were more robust.

Apples and oranges. It always seems to come down to apples and oranges.

On a side note, I got the chance to give Amateur Radio a little PR.  A woman came up to me and asked me what I was doing.  She and her lunch buddies at the next picnic table over were curious. I told her it was Amateur Radio and she looked at me like I had three heads - obviously she had never heard of it before. I asked her to Google (when she got back to her desk) Amateur Radio, hurricane, and Puerto Rico.  There are plenty of positive articles and videos out there that shed good light on our hobby/service.

Skunk for lunch

I headed outside again today with the QRP gear, to try some stuff.



1) I wanted to try a different method for tuning the magloop capacitor
2) I wanted to try a little more Reverse Beacon spotting.

Although I made no contacts, I did have success (more than I thought) with the new method of tuning the magloop. Instead of listening for the loudest receive noise with my ears, I keep my eye on the KX3's S-Meter and watch for the most bars.  Once I get there, I tweak very slowly for the loudest receive noise and then use the KX3's SWR Meters for the lowest SWR.  I was surprised how much better and quicker this worked.  It was markedly faster than my older method of just listening. I guess in my old age, the KX3's S-Meter reacts more quickly than my ears do.

The second "experiment" involved sending out CQs with the primary purpose of wondering how RBN would pick me up.  I certainly would have answered any calls, as that would have been icing on the cake, but even though I got no takers, I fulfilled my primary objective.


17 and 20 Meters got me the most distance - no surprise there. 40 Meters got me the most hits.

While it would have been more fun to have actually had a QSO, it wasn't a totally wasted effort. Tomorrow, I'll spend more time actually trying to nail down a QSO.
