Disappointment, again.

I swept the bands a few times yesterday and I could not locate any more museum ships that were on the air. In retrospect, what I should have done, and will do next year is to place a bunch of appropriate call signs in Ham Alert. I had NJ2BB in there, but band conditions were never good enough for propagation between South Plainfield and Camden. The distance between us is only 78 miles. I tried listening for them when they were spotted on 40 Meters, but even then, there was no groundwave propagation. 80 Meters would have been my best bet, but I doubt they have access to space for an 80 Meter antenna. I also kept looking at DX Summit and some of the other clusters, but I never saw anything in comments to indicate whether or not the spotted station was a museum ship or not.

The other disappointment for the weekend was the 4 States Second Sunday Sprint. I worked exactly one station and that was Mark WB9HFK, who had a terrific signal into NJ.  I also heard Chas W2SH on 20 Meters, but he was very weak. I tried calling him several times with no luck.

I called "CQ 4S QRP" a lot, with no success on both 20 and 40 Meters. On 40 Meters, I tried the 7.030, 7.040 and 7.120 MHz neighborhoods. Nada, zip zilch. In situations, like these, as unlikely as it would have been, I tend to thing maybe there's something wrong with my antennas. Afterwards, I plugged my call sign into the Reverse Beacon Network to see if I was being heard. This is what came up:


And for the most part, I was getting double digit dB numbers above the signal to noise ratio level, so I was not only being heard by the skimmers, but would have been audible to the human ear, as well. Even some of the skimmers in Europe were hearing me in double digit dB figures. That made sense to be as I had had that QSO with England just the day before on 17 Meters at only 5 Watts.

The timing for the Second Sunday Sprint is not ideal as that's the same time the weekly K1USN Slow Speed Sprint also occurs.  All you hear on 40 Meters is wall-to-wall "CQ SST". I may try another time or two before I decide whether or not it's worth attempting to participate at all.

Personal Best

I know myself all too well. I had a great time as a 40 Meter Fox last night, but now I'm paying the consequences. I knew ahead of time that following the hunt, I'd be on an adrenaline high - and I was. I was stoked, awake, and I wasn't able to nod off until about 1:00 AM.

Today, the walking dead probably feel more alive than I do.

I have to honestly say, though, that I approached the hunt last night with trepidation. I tried to catch a catnap after dinner, but my phone kept chiming with all kinds of geomagnetic alerts. The last one came about a half hour before the starting bell to tell me the k index was up to 4. I went to the propagation box at the bottom of the blog to see that night time conditions on 40 Meters would only be "fair". Uh-oh!

But whatever the sun was doing didn't seem to have too much of an effect on me. I ended up with a personal best of 55 QSOs, two of which were dupes. One was K9TA, which was just probably an insurance QSO on his part, and the other was NX1K, Mark, who came back to me a second time, but with lower power - 2 Watts. That's the QSO that goes into the record book.

Here's the Reverse Beacon Network map from last night:


While I didn't hear anyone from the West Coast, the other Fox, Randy NC4RT, did work Don NK6A. The farthest west I was able to hear and work were KS, CO, TX and OK.  The map shows that skimmers picked me up on the West coast, but my signal was probably below noise level which only computer ears could hear.

I kept switching back and forth between the MF-1982 and my Butternut HF9V. The vertical allowed me to hear those western stations much better than the wire. I was glad to have both antennas. 

Again, thanks to all the Hounds who worked me. I know there were many out there that I couldn't quite dig out of the noise. I thought I heard John K4BAI a couple of times, but he was not loud enough to know for sure that it was him. The mind can play tricks on you , if you allow it.

That was fun!

I did get on the air and joined in on the NAQCC Sprint last night. it's been a long time - too long; and I had a lot of fun. I stayed up later than I had planned as I was having so much fun! It took me a while to fall asleep as I got wired (as I feared), but it was worth it.

I started off on 20 Meters, where I worked four stations. Conditions on 20 were tough! Signals were way down in the mud for me. The EFRW was extra noisy for some reason, so I switched over to the HF9V. By far the loudest station on 20 Meters was N9EEE. I really had to strain my ear to hear the other three that I worked.

40 Meters on the other hand, was THE band for the night!  I switched back to the EFRW where my signal was even skimmed in Spain! I worked 23 stations on 40 Meters and I pretty much stayed on 7.038 MHz, running the frequency.  I worked a lot of old friends and made some new ones.  The lowest member number that I heard all night was John K4BAI, NAQCC # 644. I wonder how may people may have been taken aback with my NAQCC # 35! The best DX catch of the night was working DK1VD, Fred in Germany.


When 40 Meters dried up for me, I switched over to 80 Meters and called "CQ NA" for a bit, but had no takers. It was 10:00 PM or 02:00 UTC at that point and I decided to pull the plug. My wake up call for work comes around too quickly at 5:00 AM, so I figured I'd better at least make an effort to fall asleep. i think I drifted off somewhere around Midnight.

It was great to hear so much activity! There's nothing worse than jumping into a Sprint only to be calling "CQ" continuously with no takers, or twiddling the dial and finding no one else calling "CQ", either. That's what makes you never want to bother again.

Whew!

I managed to get the 2024 Skeeter Hunt Scoreboard back online yesterday. It took me longer than I thought it would, but it's done and back up. You can either go to the Skeeter Hunt Webpage or the Skeeter Hunt page of this blog and the links will get you there.

In a way, it's a good thing this happened, as it's compelling me to get the certificates out for the 2024 Hunt. These stupid healthcare problems really have thrown me for a loop since last September. I apologize for the delay. I've also given the bonus for 2025 more thought and we're going to play Skeeter Blackjack. Work enough stations to have their call sign districts add up to 21 and you'll get the bonus points. The 0 area call signs will count as a face card worth 10 points.

For example, if you work N0MII NK9G and W2LJ - that 10 + 9 +2, equaling 21.. You could also work, for instance K4BAI, N5GW, K3RLL and WB9HFK and that would also add up to 21. Any number of call signs would work, even if you ended up working ten 2 area call signs and one 1 area call sign! Whatever it takes - I think this is a pretty easy concept to understand and should be fairly easy to accomplish. Of course, as part of the Log Summary, each entry will have to list the call signs worked to prove that they are eligible for the bonus points.

I also decided to participate in the Flying Pigs Run for the Bacon last night. It actually got up into the low 70s yesterday and the basement was comfortable enough to sit in without turning on the space heater. Beginning at 23:00 UTC, I started calling "CQ FP" on 20 Meters and worked a couple of stations. After a while, I switched over to "hunt and pounce" and after more than just a few dial twiddles, I heard no one and moved on down to 40 Meters.

40 Meters was wall to wall Virginia QSO Party stations and I only heard one solitary Piggie calling CQ around 7.030 MHz and worked him. Then, as it was getting close to 00:00 UTC, I went and checked into the St. Max Net at around 23:50 UTC. A lot of stations participated last night and at about 00:25 UTC, when the net closed, I went back to the lower part of 40 Meters to see if I could work a few more FP's. No dice, this time it was wall to wall SST stations. It was nice to be on the air, but at the same time a bit disappointing to work only three Flying Pigs. According to the RBN, I was getting out really well last night. Orange is 40 Meters, Purple is 20 Meters - and a vast majority of my signals were being heard at double digit dB levels above the noise floor.


Wednesday night is the monthly NAQCC Sprint. I am planning to participate in that for the first time in a very long time. I've been having trouble sleeping of late. I think I've been turning in too early as I fall asleep fairly quickly, but wake up around 2:00 AM and then I'm not able to fall back asleep for another hour or so. After the Flying Pigs Sprint last night, I went to sleep a bit later than I'm used to as of late and pretty much slept the whole night through. So once more, it's Amateur Radio to the rescue!

As seen on Facebook

I saw this posted on the POTA/SOTA Facebook page, and thought it would be good to share here:


I know that I am myself guilty of not following procedure, with the end result of me muttering swear words under my breath every time I have to untangle my Dacron rope supply. Thanks, Scott W3GTR for the excellent photos!

My instincts for last night's 40 Meter Fox Hunt proved to be true (for once)! I found Steve WD4CFN's Hounds rather easily, went down 1 kHz and was able to hear him amongst the "CQ NA"s that were in plenteous supply - I'm guessing last night was the NAQCC monthly Sprint? Anyway, as I was saying, I found Steve rather easily, but he kept fading in and out. He would be strong for a few minutes and then fade to ESP for a few minutes and back and forth, and back and forth. On a peak, i worked him at 02:28 UTC, 559 both ways.

John AJ1DM was just as I expected. I found "a" Hound calling him and again, went down 1 kHz and listened and heard nothing. In order to not make the same mistake I made last week, I then went back up that 1 kHz, just in case John was working simplex. Nothing there either, so I pulled the plug so I could get some shuteye.

Looking at his log this morning, the closest state to me on the East coast that John worked was North Carolina. It was obvious that his RF was flying as high overhead over New Jersey as these storied drones (which I have not seen) are. And I was surprised to see that neither Jack N2RK or Tom KV2X in NY had worked John. Those two guys must have amazing antenna systems because it seem like they work everyone - sometimes being the only East coasters to make it into a Fox's log.

Once again last night, my weapon from the antenna quiver was my vertical, my Butternut HF9V. Steve WD4CFN's signal was the same 559 on the EFRW and the vertical, but the vertical was not picking as much background noise as the wire was.

The weather for NJ today will be on the warm side with a high in the low 60s. We'll get some drought busting rains with 2 - 3 inches expected between today and tomorrow. We'll still come up short rain-wise for the year, but at least the wildfire/brushfire danger is now pretty much over.  We're also expecting some pretty ferocious wind gusts later today and tonight. I hope the outdoor Christmas decorations don't take flight!

Instincts

The two stars of tonight's 40 Meter QRP Fox Hunt are John AJ1DM in Rhode Island and Steve WD4CFN in Tennessee. Based on the people I've been able to hear on 40 Meter SSB on the St. Max Net, I'm thinking I should be able to hear Steve, but John may be a challenge. I think it's more likely that I'd have a better shot of working Rhode Island on 80 Meters.

My own 40 Meter Fox experience from November 13th bears this out. I worked Steve WD4CFN, but no Hounds from the New England states at all.

The HF9V's "renovations" continue to impress me. In fact, the pelts that I was able to grab last week were all gotten through the HF9V. The way I have it tuned is that it really likes the CW portions of the band. I tried using it in the SSB portion of 40 Meters on Sunday for the St. Max Net and it was not happy. I had to resort to the EFRW, which was not a problem.

It will be interesting to see how my prediction turns out - if I'm able to stay awake long enough.

What a difference

a week makes!

I'm talking of propagation and the 40 Meter Fox Hunt which occurred last night. I was tired after a long day at work, and I wasn't going to ...........but then my Polish stubbornness licked and I headed downstairs at about 8:45 PM.

I turned on HamClock (I don't like to leave computers plugged in and running while I'm not home)  and I saw that Dave AB9CA was spotted in the POTA box, so I tuned to the frequency and was able to hear him at about 449-559. He was in Oklahoma and after a few tries I was able to grant him a QSO towards his activation.

Was that a portent of things to come?  Sort of.

When the clock struck 0200 UTC, I was able to find Jim N0UR rather easily. I didn't even have to look for his pack of baying Hounds, He was in the clear and the Minnesota to New Jersey pipeline was in full function and I worked him at 0206 UTC. I went back and worked him a second time closer to 0300 UTC because for some reason, I wasn't showing up on the live QSO map that some of the Foxes use. A look at his log this morning confirmed the 0206 UTC QSO and he deleted the dupe. Sorry for that, Jim!

Randy NC4RT was a whole different story. I worked him last week when I was the Fox and he was the Hound, so I expected that would hold true last night. You know what they say about making assumptions.

I found the chasing Hounds easily enough at about 7.0325 MHz and tuned down 1 kHz, where I expected Randy to be. Nothing. I think I may have heard a whisper of him once, but that was probably just my mind playing tricks on me. What didn't help at all was a slow speed QRO rag chew taking place right on the frequency! I thought I might stand a chance when the rag chew was over, but the one station started calling CQ again, so I just gave up a little bit after 0300 UTC. I was beat and tired and I didn't think propagation was going to improve enough in the last 25 minutes to make it worth my while. BUT, before I left the shack, I did fire up RBN to see where Randy had planted himself and I was right! He was being spotted at 7.0315 MHz, just where I thought he'd be. I just couldn't hear him at all .......... and just last week he had a decent signal into NJ on 40 Meters. Go figure.

I've said this so many times that it shouldn't surprise me.  When you think you have this whole propagation thing figured out? Think again!

On another subject - I removed the little globe -visitor map widget from the right side of the page. They hadn't renewed their security certificate and Google Chrome (which I use) won't display it, so rather than leave a hole, I deleted it. When I get some time, I'll look for an alternative.

When I was a kid

we used to call this "Indian Summer". I don't know why or how the term originated, and I suppose it's not politically correct to use it anymore. After the first frost or series of really cold nights of Autumn, there's usually a return to a few days of Summer like weather. We're going to experience that today, tomorrow with a tail off on Wednesday with a high of 81F (27C) today, 82F (28C) tomorrow and 78F (26C) on Wednesday. From there on it's down to seasonable temperatures again.  As much as I prefer the warm weather to the cold, I've started getting used to chillier "sweater weather", and the onset of early darkness. I wouldn't mind the warm up if it would hang around for more than just a few days. This is just a tease of my favorite season that I'd prefer to do without. Breakups are best when you don't look back. LOL!

I was delighted to see an e-mail from DXEngineering in my inbox this morning. I placed that order for the Butternut replacement parts yesterday morning and according to FedEx tracking, I will have them by end of day tomorrow. That is fast service! The extended outlook for Saturday is for partly cloudy skies with a high of 66F (18C), so it should be a good day for Butternut repairs. Not sure when Saturday as Hadley Communications Technologies, the 501 C3 company that provides funding for SPARC is having a clothing drive fund raiser and I promised to help out at the drop off point. I will get the repairs done on either Saturday or Sunday, though, as I don't want to place all my bets on continued good weather for the long term. I don't want to go the entire winter without having the HF9V available to me.

Speaking of the early darkness - that means that conditions for 80 and 160 Meters should be improving as we head further into Autumn and Winter. I checked into the St. Max Net last night which has been on 40 Meters for the Summer. The QRM from shortwave broadcast stations has been horrific. I hope the net plans to return to 80 Meters soon, as it was hard copying weaker stations over the heterodynes. 80 Meters may cut down on the reach of the Net a bit, but it's a lot more comfortable listening there.

So far my MFJ-1982 HP seems to be performing as well as KD2FSI's has been performing for SPARC Field Day the past few years.  The antenna fits nicely into a slightly different configuration, as it is a bit longer than the W3EDP. I had to get a little creative to make it fit. My midpoint mast used to be even with the backend of my neighbor's garage. Moving it to the last chain link fence upright post on that side of the yard did the trick.


Of course, the UNUN is bigger on this version, than the one on my 1982 LP, as that was designed to handle 20 Watts maximum. I had really wanted to purchase the MFJ-1982 MP version, which was designed to handle up to 200 Watts, but they were sold out already. Since I run up the power for the St. Max Net up to 85 Watts, the 1982 HP is a bit of overkill, but it was my only recourse.

I suppose I could have gone with an antenna from a different vendor, but I am familiar with the MFJ-1982's from Field Day, so it seemed to make sense to go with what you know that works.

Maps a lot

No. Not the Monty Python musical Spamalot - this is Maps a Lot. A comparison of RBN Maps vs. QSO maps from my POTA Activations last week. Just to see if and how they differ.

First - Keewaydin State Park, US-2088:

The Reverse Beacon Network Map

Actual QSO Map including the Alaska QSO

Closer look at just the Continental US QSOs


And now Kring Point State Park, US-2091:

The Reverse Beacon Network Map


The QSO Map

The QSO maps (courtesy of Log Analyzer 3.2 by DL4MFM) pretty much gibe with the skimmer maps, just as you'd expect. There are some discrepancies, though. From Keewaydin, I made it to Alaska, a bit farther than the skimmer in the Canadian North West that picked me up. Also, the RBN map didn't show me as getting out to the South West, but I did have a QSO with Oklahoma.

The RBN Map for Kring Point had no skimmers in the Western US pick me up, but yet I had a QSO with California. And I had a QSO with Arkansas, where the RBN map showed no skimmers picking me up. But even with the discrepancies, the Reverse Beacon Network is a great tool which allows you to get an idea of how your RF is getting out.
 
Just for reference, I was located in NY State right at the border with Canada, pretty much opposite of Ottawa. The RBN Maps are showing my signals as originating from my home QTH in New Jersey, so there's a bit of inaccuracy there.  The QSO maps show the origination point accurately. I think RBM goes by your call sign info, not where you're actually located at the time.0

Lesson learned from all this? You're definitely getting out and being heard to where the skimmers can capture you, and if your snr figures are in double digits- probably a lot farther.

A week later and I'm still astounded that the AX1 table top antenna completed QSOs with Alaska and California. As Craig WB3GCK says, "It defies logic."

Final thought - with all this geomagnetic activity happening right now, I'll bet the Northern Lights are quite pretty up in Alexandria Bay. Sigh. Seems I'm always a day late and a dollar short.

The weather this weekend was frightful

 Not scary, frightful, just frightful activity wise.

I got soaked coming home on Friday. I was following the weather and radar all day and was expecting thunderstorms here at work when I left for the day. It was bone dry, but the skies were darkening. All the way on the drive home, I could "feel" that darkness behind me, rather then see it in the rear view mirror. As luck would have it, as dark as it was, it didn't rain and I thought I would beat the storm home. As I got out of car in front of the house (I park on the street), there was a cloudburst. It began raining at a rate of over an inch an hour, with huge, heavy drops that actually hurt when they landed on my arms. I got drenched enough that I had to change clothes once I got inside.

That set the tone for the weekend's weather. It was so humid that the lawn didn't dry out all of Saturday, so we couldn't mow. And that was actually a good thing as the temperature/humidity index made it feel like it was over 100F. We probably would have ended p with heat exhaustion. I told my son that if worse comes to worse, we'll buy a sheep. HI! We ended up getting hit with more thunderstorms and about 0.69 inches of rain later in the afternoon. I was going to grill burgers for dinner, but had to resort to indoor cooking instead.

On Sunday, I got on HF for a little bit around 1:00 PM (17:00 UTC). The bands were a mess. I did not hear anyone on any band except for 20 Meters, where I heard a solitary station, NM8GS around 14.038 MHz. 


It was the light ship Huron that was on the air for Lighthouse and Lightship Weekend. They was calling CQ and I worked them easily on the first try.  That was when I looked up at HamClock and saw that the K Index was at 6.3. Argh! The bands were pretty much a wasteland. Speaking of which, I just recently downloaded the SpaceWeatherLive app onto my phone.


It's a freebie and you can find it in Google Play and the iTunes store. You can set it up so that you will be alerted whenever there's a solar flare or a CME. A good tool for those of us who are denizens of the HF bands. It was not difficult to understand why the bands were so noisy and dead at my QTH as I was getting alerts for M Class flares almost continuously!  One approached M7.2 on Saturday afternoon - almost X Class! I was also getting alerts that there were "minor" radio blackouts. Ha! They appeared to be a bit more than minor at my QTH!

I ended up using the time to fabricate my "new" drive on mast holder. I wanted to take pictures of it "in action" so to speak, but due to even more thunderstorms yesterday afternoon and early evening, that became an impossibility. Today is supposed to be dry all day, so maybe tonight I'll get the chance to get a few quick photos. I did something a little different this time and it's easier to explain with photos as a visual aid.

We ended up getting an additional 0.72 inches of rain yesterday, so we got over an inch and a half for the weekend. Up until recently, it's been a very dry Summer in South Plainfield. Whenever a heat wave broke with thunderstorms, it seemed they always skirted to either the north or south of us. We're making up for that now. Tomorrow evening there is a 605 chance of showers and thunderstorms, which I hope does not pan out. Tomorrow evening is National Night Out, and SPARC will be at the event, handing out literature promoting Amateur Radio to the community. I'd hate for rain to spoil the event.

Also, I've been keeping an eye on Hurricane Debby. It looks like as she winds up the East Coast, she'll be downgraded to a tropical storm, but there is potential for major flooding either Thursday or Friday.  Hurricane Ida is still fresh in my mind when we got 9" of rain in one day, just a few years back. We lost Marianne's car when the parking lot where she works became a lake that night. I don't want to go through that again!

The heat

Yesterday was a CERT day. Like those bumblebee shirts? I should wear it NEXT Sunday! Hi!


From left to right, Bill Meixner KC2PLO, Sharon Padula (non-Ham), Marv Bornstein K2VHW, W2LJ, Captain Wendell Born, our OEM Director - photo courtesy of Councilwoman Christine Faustini

As I had mentioned earlier, the South Plainfield Business Association put on their annual "Christmas in July" celebration.  Santa was there for the kids, but it's mostly an opportunity for businesses, mostly local small businesses to display and offer their wares and to increase their visibility within the community. As CERT members, we were there to hand out literature about hurricane preparedness, flooding preparedness and to possibly. recruit more CERT members. 

The event ran from 4:00 PM to 8:00 PM in order to beat the peak "hot hours" of the day, but it was still pretty hot. I took out my cellphone around 4:30 to check and see what the temperature was at my weather station located about a mile away, and I was seeing a reading of 93 F (34 C). Captain Born is one smart cookie, though. He set up a fan/mister combo right in front of our canopy which insured many stoppers by. I only wish he had pointed the thing inward instead of outward!

Marv and I both made a mental note to make sure we ask him if we can borrow that for next year's Field Day effort. But sitting there in the heat made me think about next Sunday's 90 F (and possibly higher) temps for FOBB. I'm not going to have the advantage of having that mister at Cotton Street Park. And even though it's pretty shady there, if there's no breeze and the air is still, it can get downright uncomfortable.

So once again, I whipped out the cell phone and ordered one of these portable neck fans.

It was only $12 on eBay and should be at my house either Friday or Saturday in time for next Sunday's event. When I was a kid, the extreme heat or cold didn't bother me so much. I grew up in a house with no air conditioning, and it was only later at my time at home that my parents put window air conditioners in a couple of rooms.  As one grows older, let's just say we grow more appreciative of the more temperate range of climes. I doubt I could live in a house without A/C again.

Earlier in the day, before I left for the CERT event, I spent some time down in the shack and worked four POTA stations. Signals on 20 Meters were really down and in the mud. The only signal louder than 559 was K8ARE at US-4239 in Ohio. He was 599, everyone else I worked was either 559 or even fainter. I hope propagation is better next Sunday, and again on August 18th!

Odds and ends

I managed to get outside for just a few minutes yesterday as the moon was approaching maximum coverage of of the sun (90%) at 3:24 PM local time.  I took a small shipping box and punched a hole in the side with a thumbtack. It projected a very tiny, but totally sharp image of the moon covering the sun revealing only a small crescent of sunlight. Of course, this is New Jersey after all, and clouds came in for the actual moment of maximum eclipse. But I can say I saw it. This reminded me of the eclipse of 1972, when I had my 3" refractor telescope set up in the backyard, projecting a magnified image onto a white piece of cardboard.

A co-worker managed to snap this with his iPhone.

BTW, Sean Kutzko KX9X was doing some AM Broadcast Band DXing during the eclipse. He observed that during the maximum period of darkening at his QTH, he was able to hear AM stations from over 500 miles away, that he normally can only hear at night. The D Layer was definitely affected! He recorded the AM Band during the eclipse from start to finish and will go over it in detail over the next few weeks, in order to get a better feel as to how propagation was affected.

I saw on Facebook yesterday, where Alex PY1AHD of AlexLoop fame has become a Silent Key:

It is with extreme sadness and sorrow that I share the passing of our friend and colleague Alex Grimberg (PY1AHD), AlexLoop, due to his renowned work with magnetic loop antennas. Inestimable loss for Brazilian amateur radio, an enterprising and visionary colleague - We are all saddened.

I got word from my friend that he was encouraged by your comments regarding using a local WebSDR as a receiver. He was able to hear stations on 20 Meters via the Web that he was not able to hear on his K3, due to the solar panel noise. He made three successful QSOs on 20 Meters and will most likely use WebSDR for making contacts on 14 MHz and above. Thanks for your encouragement! I'm very happy for him - he had been disappointed (that's putting it mildly) with his situation. It's good to know he can be on the air again.

My KM4CMT EFRW UNUN kit was delivered yesterday. I hope to have it built and ready to go for "Amateur Radio Day At The Library" on April 20th. If I don't have it ready, I'll probably employ the PAR ENDFEDZ or perhaps the EARCHI EFRW that I already have in the backpack. It's not that the kit is a complicated build - far from it. It's a matter of finding time. The next few weekends are really filled up now that lawn mowing season has started up again.

Yikes !!!

 


A Coronal Mass Ejection (or other solar phenomena) has rendered the bands positively yucky today. But for the limited amount of time that I spent behind the key today, I still managed to snare six POTA stations for the log.

WD8RIF at US-1994

K2EAG at US-1619

KU8T at US-1637

WI2X at US-1611

AE4WX at US-6962

W0ABE at US-10533

All contact were made on 30 and 20 Meters. I heard EA4HCF calling CQ on 17 Meters and I tried answering, but no joy at 5 Watts. For the heck of it, I tried bumping up the KXPA100 to 85 Watts, just to see if I could make contact. Nope - that tells you that the bands truly did bite. I usually rarely have a problem reaching Spain with 5 Watts, let alone 85 Watts.

Last week the POTA powers-that-be changed all the designators from "KA" to "US". Earlier in the month, they changed Canada from "VE" to "CA" and all of Great Britain from "G" to "GB". Not exactly sure what was the reasoning, but I'm sure they had a good one.

It will be interesting to see if I hear anyone on the St. Max Net tonight on 75 Meters.

I was going to go out today and play around with the Buddistick on top of the Jeep, using that magmount  on which I replaced the coax cable. It's in the upper 40s and normally, that wouldn't be too terrible. We're getting a steady breeze and wind gusts that are making it downright uncomfortable to be outside. This is the day after that Nor'Easter blew through here yesterday, dropping 2.72 inches of rain on my QTH. I'm hoping that maybe next weekend will be warm enough for me to run some quick tests without allowing my hands to go numb.

Propagation is a funny thing

When you think you have it even somewhat figured out ...... you don't.

I had two VHF ARES Nets to check into last night. One for the Southern District of NNJ at 7:30 PM and then the actual NNJ Section ARES Net at 8:00 PM. Before, between and after I decided to do some POTA hunting. I worked Dave AB9CA in New Mexico easy enough, but there was a station in Illinois on 40 Meters that I could not get as hard as I might try.

This is unusual, because I normally have a pipeline on 40 Meters to Illinois, Indiana and that part of the country. It was a bit frustrating to say the least. Most times, I can connect with a station from that part of the US after a call or two. Not last night, as I tried switching between the Butternut and the W3EDP, as well as adjusting my frequency so that I would not be zero beat with the activator. He finally went QRT just as about the Section Net was starting. This did not bode well for later in the evening as Don K9DRP in Illinois was one of the 40 Meter Foxes last night.

The other Fox was John AJ1DM in Rhode Island. John was an easy find and was loud enough, but there was constant QRM on him as QRO stations were all around him.  It took some really tight KX3 filtering to isolate John well enough to be able to easily hear who he was working. Finally at 0147 UTC, I got in his log.

As I suspected, Don K9DRP was another story. Not only did I have to utilize the KX3's Audio Peak Frequency feature in order to hear Don well enough, there was also a ton of QRM on him as well. This QRM (in both cases) wasn't intentional. It was just QRO stations who didn't hear the QRP stations underneath them.  That happens and we get used to it. Again, as with the POTA station earlier in the evening, I was trying everything I knew to get Don to hear me. I switched between vertical and wire, and I kept track of who he was working and tried to anticipate his next listening spot. I even tried adjusting my CW speed, thinking maybe a slower or faster speed might catch his ear. All to no avail.

I was about to throw in the towel, as I was tired after a long day at work and it was getting late, but I decided to stick with it to the bitter end. My perseverance was rewarded by hearing "W2LJ" come back to me at 0221 UTC - with only 9 minutes to go before QRT time! A quick exchange with no requests for repeats from me, and I was in the log. Whew!

One other thing this Fox hunting is teaching me, besides perseverance, is that I really do need hearing aids, or at least one hearing aid. My right ear is almost totally shot. The nice thing about the KX3 is that it has the built in sub-receiver and it also has dual listening mode. When you utilize it, the main VFO, in this case the Fox, will be in my left headphone and the the second VFO, the Hounds, will be heard in my right headphone. I cannot hear anything from the right headphone as things stand. I literally have to take the headphones off and flip them so I can figure out where the Fox is working the Hounds. What a pain!

Last week, I went for my annual physical and my Doctor looked in my ears, as I told him I was going to need hearing aids. He told me that there is some rumen (ear wax) build up in my left ear and that I should get that taken care of, but my right ear was totally clean. He was a bit surprised when I told him that the right ear was the ear I could not hear well with! I have looked into Over the Counter hearing aids, but they are mostly for folks with mild to moderate hearing loss. An OTC hearing aid would be good enough for my left ear, but my right ear falls under the severe hearing loss category. "Regular" hearing aids are expensive, but several friends who use hearing aids have recommended the ones available through Costco.

Maybe this summer - yeah, along with a lot of other things.

A good HF day

Yesterday was a good radio day. Not only was it a good radio day, but it was a good day weather-wise, as well. It got up to 68F (20C) in the afternoon, making the basement shack a lot warmer as well, where it was 62F (16C). Still not ideal, but a lot more comfortable than it has been and I was in no hurry to leave for warm-up breaks. I still have to get a space heater for down there. I'm sure there's still lots of cold weather left before Ol' Man Winter sings his swan song.

But I digress. 10 Meters was hopping and I worked a Polish POTA station, a SOTA station in England and Alex RK3ER, whom I have made contact with several times before. He was BOOMING in at 599 +++++, easily the loudest signal on the band.

I worked a bunch of POTA stations on both 10, 15 and 20 Meters. Even with the SSB DX Contest going on, the CW bands were quite populated and humming. It was nice to hear. An added treat was to work some fellow QRP'ers and Skeeter Hunt stalwarts this weekend, Craig WB3GCK at K-4363 Norristown Farm State Park in PA, Eric WD8RIF at K-1994 Strouds Run State Park in OH, Paul AA4XX at Mayo State Game Land in NC, and John N0EVH at K-11042 Kahrs-Boger State Conservation Area in MO. I always go out of my way to fatten up a fellow Skeeter's log if I hear them performing an activation.

Later, at 0000 UTC, I checked into the St. Maximilian Kolbe Net to cap off the day. Thankfully, the KXPA100 was in tip top shape and I was able to boost the power to 85 Watts for that. I shared something with the guys that I had never heard of before.

Of course we all know there are plenty of OTAs on the air - JOTA, POTA, SOTA, IOTA and so on and so forth. Did you know there's also a  CHOTA? There is and it stands for Churches and Chapels On The Air. It originated in England, but has "jumped the Pond" in recent years, with some American churches joining in. Here's a link to an article I saw on AmateurRadio.com - https://www.amateurradio.com/chota-2024-is-announced/

Unlike the other OTAs, CHOTA is a one day event and this year it will be held on Saturday, September 14th. It might be a good way to get some family friendly media attention for Amateur Radio. I'm thinking I might bring this up at the next SPARC meeting. Maybe we can put a church in town on the air. I know my Church, Sacred Heart, has a HUGE parking lot and maybe we can draw some attention to Amateur Radio during the day and before the 5:00 PM Mass - that is if I can get our Pastor to sign off on the idea.

Weather and band conditions

I worked the 40 Meter Fox Hunt last night - for the first time in a while, I actually had enough energy to stay up and do it. Added to that, the basement had warmed up to the low 60s, as we're in the midst of Spring time temperatures. The overnight low held at 54F (12C) and it was rainy. The only bad thing was that 40 Meters sounded like it was in full time "Summer mode" with lots of static crashes and noise. From looking at the Web, I see that some areas of the upper Midwest were experiencing severe weather conditions and that some places even had tornado warnings put in place.

The other reason I joined the Hunt was a somewhat selfish one. The two Foxes were Drew K9CW in IL and Dave N1IX in NH. I usually can hear the both of them quite easily and last night did not ruin that pattern.

I came across Dave N1IX in the upper portion of the Fox area right off the bat. He was LOUD and I thought to myself that Drew would be even louder, because he usually is. So I went hunting for him, found him and to my surprise, he was a bit weaker than I had expected. He was an easy 579, but he usually blows the cans off my head.  Evens o, I got in his log after figuring out where he was listening. and switching from the Butternut to the W3EDP. I called several times on the vertical with no joy. I switched over to the W3EDP (which is a bit noisier for me on receive on 40 Meters) and got him on my first call via the wire antenna.

Then I went back to the frequency that I had written down for Dave and nabbed him soon thereafter. Dave was 599+ and was so loud, it almost made you wonder if he had previously gone QRO and had forgotten to return the rig back to 5 Watts for the Hunt. However, experience tells me that is just how propagation works, sometimes. So much for the guys who insist that QRP signals automatically equals weak signals!

When the Hunt is over, or after I have been lucky enough to nab both Foxes, I like to go to the Reverse Beacon Network and see how the Foxes are being heard, and where.

Here's Drew's map:


As you can see, Drew K9CW was being heard from coast to coast. Totally respectable and I wish MY signals propagated so well. Still, I was surprised by his less than robust usual signal. Maybe the stormy weather in the Midwest attenuated his signal.

Dave N1IX, on the other hand:

If we had any Hounds in Europe last night, they would have been in for a treat!

Getting back to the weather, it's a warm but rainy day in New Jersey. The high temp this afternoon is supposed to approach 60F. Of course, it's February and that won't last as a cold front is supposed to come rushing through overnight. In fact, the lightning detector app in my phone detected some strikes very early this morning around 3:00 AM, but they were more than 20 miles away.  So before I left for work today, I made sure to go down the basement and disconnect the antennas just in case we get any localized  afternoon thunderstorms. Better safe than sorry.

Tuesday night 40 Meter Fox Hunt ...... grrrr

 


The evening started off in the best possible manner. I stumbled upon Drew K9CW's loud signal from Indiana right off the bat. Realizing that this loud signal was indeed one of the Foxes, I quickly called him and worked him at 0202 UTC. Two minutes in, I think that's the earliest I've ever worked a Fox in all the years I've been doing this.  Drew had a fantastic signal - an actual 579 and if you look at all the blue and green dots on the map above, you'll see he handed out a lot of pelts.

John AJ1DM in Rhode Island was a whole different story. If you look at the red and green dots on the map, you'll see he handed out a lot of pelts as well. But if you look at the map carefully, you'll see there are no red dots from Ottawa to Washington DC, save for a solitary green dot in New York, a Hound who was able to work both John and Drew. It's hard to see in the photo above as he's right behind that blue dot in northwest New York State. John's RF was literally flying right over our heads destined for other distant Hounds, away from the Northeastern states.

I could tell where John was by listening for the pack chasing him, and then going down 1 kHz. After the hunt was over, I plugged him into RBN to see if I was correct in guessing where he was. It turned out that I wasn't chasing phantoms - my detective work proved fruitful, and I had the right frequency all along. Sometimes when signals are so weak you can fool yourself into hearing something that's not really there. Happily, that wasn't the case this time.

I was able to hear him only by using the KX3's APF function, and only then at ESP levels. I knew he was there, but that was about it, save for one single time when his signal rose out of the background well enough to throw out my call. He promptly returned to the dust of the noise floor, and at about 0300 UTC or so, he completely vanished and I was no longer able to hear his ESP level signal. Determined, I hung around to the bitter end, hoping that John might somehow re-appear (loudly) - but no joy.

So I guess one out of two isn't bad. The HF9V was the weapon of choice last night and served me well in being able to retire for the night with at least one Fox pelt.

When will it end?

 QRP Image of the Day

A couple of iterations of the Four State QRP Group Bayou Jumper - photo by Gary Chambers, Jr.

So the question for the day is, will my newly found QRP Fox Hunt streak come to an end tonight? Will my luck finally run out?

Tonight's Foxes for the 80 Meter Hunt are Jim N0UR in Minnesota and Wayne N4FP in Florida. Just wondering if either or both of those two states are too long of a haul for a QSO from New Jersey on 80 Meters. Jim has always had a decent signal to New Jersey, but I have my reservations. I don't have my AC Log on this computer. I'd like to open it up and look up the previous contacts I've had with both of these Foxes to see if any have ever been on 80 Meters. Tonight will tell, I'll just have to be patient (not one of my strong suits). And if I do work either Fox tonight, which will be the hero - the W3EDP or the Butternut?

No radio last night except for a brief check-in to K2VHW's Middlesex County Chat Group Net on 70cm on the way home from the Middlesex County Fire Academy last night. We had our monthly CERT training and last night was a review of basic firefighting using fire extinguishers for small trashcan type fires. Each one of us got the chance to extinguish a small controlled burn set by the Chief of Firefighting Education at the Academy.

The keyword in those situations is PASS

P - Pull the pin

A - Approach (staying as low as possible) the fire and aim the nozzle at the base of the fire

S - Squeeze the handle of the extinguisher.

S - Sweep the nozzle from side to side.

Two other important points:

NEVER turn your back on a fire - while approaching or leaving, even if you think you've extinguished the fire. Always back away. Secondly, always have a "buddy" go with you if at all possible. This second person is there to guide you as you back away as well as to help you should something unexpected happen.

Happy camper

You've all heard the expression, right? "He's a happy camper!" or "She's a happy camper!" This morning I have to say that "I'm a happy hunter!"

Last night was the 80 Meter QRP Fox Hunt and I stayed up past my bedtime to participate. Before I get into talking about the Hunt, I'd like to reminisce for a bit. I can remember many days when I was in my 20's when I could put in a full day of work, come home and eat supper and then stay awake until about 2:00 AM melting solder in whatever Heathkit I happened to be working on. I'd go to sleep for maybe three or four hours and then wake up, fresh as a daisy, and start the whole process all over again without giving it a thought.  Them days are gone forever! Now I depend on my close friend and associate - Mr. Coffee (actually Mr. Keurig) to get me through the morning after a Fox Hunt. I'll probably end up hitting the sack a bit early tonight.

As I was saying, last night was the 80 Meter Fox Hunt - running from 9:00 PM EST to 10:30 EST - hence the reason for my less-than-awakeness this morning. I got down to the shack early and worked a POTA station on 40 as a warmup and even chased TX7L on the Marquesas Islands for a bit on 10 Meters. They were 229 at best, so as expected, there was no joy there.

At the 0200 UTC starting bell, I started twiddling the dial, beginning at .3.550 MHz and working my way up. I don't have a PX3 waterfall display, and although there is software available that is compatible with my KX3, I don't have it loaded onto my computer. I guess I'm too much of a fossil, I'm more comfortable with ol' tried and true. 

Anyway, I didn't find the Lower Fox or any evidence of the Hunt between 3.550 MHz and 3.560 MHz, so I continued my climb upwards looking for the "Upper Fox". Sure enough, I happened upon N8SS, Earl in Michigan, handing out pelts in a fast and furious manner.  I switched between the W3EDP and the HF9V to see which was giving me better reception. The HF9V proved to be the weapon of choice for the evening. Not so much that the signal was louder, as they were both about equal to my ear, but the HF9V had a bit less in background noise on it last night.

Thanks to the KX3's Dual Receive feature, I was able to plug Earl's QRG frequency into the second VFO and twiddle until I found the Hounds he was working. From there, it was just a matter of throwing out my call sign each time he finished an exchange with another Hound. Finally, at 0219 UTC, Earl heard me and added me to his log.

The Lower Fox, John K4BAI was going to be a bit more difficult. I hadn't heard anything during my first foray through the Lower Woods. Perhaps I had twiddled too fast. With a bit of trepidation, I set out to find him.

Starting again at 3.550 MHz and slowly dialing upward, I finally heard some call signs of familiarity - other fellow Hounds. From their frequency, I figured that John must be 1 or 2 KHz down, so I concentrated on listening there. Slowly, and I mean SLOWLY, John's signal started to come up. Propagation was changing a bit in my favor this time. I waited until K4BAI's signal became consistently 559 before throwing out my call. No sense in QRM'ing someone else if I wasn't able to tell if John was coming back to me or not. Finally at 0238 UTC John heard my call and we completed the required exchange.

I was a bit pumped because that put me at 4 for 4 in the first week of the 2023-2024 Winter Fox Hunt season. Well, actually 3 for 4, probably.  When N8SS posted his log this morning, I see that he has my name as "Barry". The scorekeeper will probably toss the QSO as invalid because of that, but I could give a tin whistle. I'm in these Fox Hunts for the personal satisfaction of participating. I really don't care how I stack up against the other Hounds when all is said and done. If I get 2 or 3 pelts every week, I'll end up somewhere in the middle of the pack. I don't need to be the Alpha Hound. So as far as I'm concerned, I went 4 for 4 this week, my first foray into "The Woods" in a long time. I know this won't last and there will be times when Lady Propagation looks at me and says "Not tonight, Sweetie!", but it was sure nice for the first week!

Like I've said before, tonight will probably be an early hit-the-sack night, but not before I put together some exam packets. Tomorrow is our monthly VE Session and we have six candidates coming - possibly five new Techs and one possible upgrade to Amateur Extra. I like to get all the paperwork set up in individual manila file folders so there's less work and confusion the morning of. Better remember to stop at Dunkin' on my way in. I have a feeling I'll be needing more Mr. Coffee tomorrow morning, too!

Solar report


With ARRL Sweepstakes CW coming this weekend, I thought it would be a good thing to post the solar forecast.

And so it begins for Central New Jersey:


One of the chores I will have to complete this weekend is to go out and buy a new winter coat/jacket. My old one was so battered and tattered that I had to pitch it last Spring. I really don't like the weather this time of year.
