ARRL Parks On The Air Book

By: Bob K0NR
30 October 2023 at 20:28

I was happy to contribute an article to the recent ARRL Parks On The Air (POTA) book. This piece is based on my Pikes Peak mountain topping article that appeared in the June 2023 issue of QST. This book is a collection of articles about POTA from 14 different authors, each writing about a different aspect of the program. The articles are all easy to read and generally provide a first-hand account of how the author has experienced POTA operating. There is plenty of beginner information and operating tips sprinkled throughout the book. More experienced POTA enthusiasts will probably pick up a few new ideas as well.

The Table of Contents below lists the articles and authors, giving you a good idea of the material covered. The meat of the book is only 118 pages long and it is quite easy to read.

My piece covered the triple activation I did from the summit of Pikes Peak, combining POTA, SOTA, and the June VHF Contest into one mountaintop adventure. For POTA, the park was the Pike National Forest (K-4404). I’ve done this type of combo activation in the past, sometimes just SOTA + POTA or just SOTA + VHF Contest. This time I did all three.

The book is available directly from the ARRL or from the usual book outlets such as Amazon.

CQ WW SSB 2020

By: m0blf
26 October 2020 at 19:01
For the last 15 years I have almost always operated CQWW SSB from M4A in the multi-single or multi-two categories. It’s one of the highlights of my year. However, with the current coronavirus situation limiting our ability to meet up, I found myself limited to a single operator entry this year. I decided to go…

This Battlestation is Fully Operational

By: TJ Campie
11 July 2016 at 14:11
After I left you on the last post I had decided I was going to run a 240v AC line to my shack as well as a secondary 120v, 20A line for my computer and radio stuff.  The idea was to get all this on line before the IARU HF Championship contest over the weekend so I got up early Friday (before my wife got up and complained that the power was off) and got to work.  It took a whole lot longer than I had planned but the finished product is pretty clean and runs the SB-200 really well.  My idle HV now sits at 2500v instead of 2400v and only sags to 2100v instead of 1800v.  

In my last post I mentioned that I had planned to try out those Svetlana tubes I got at Hamcom last year in my SB-200.  I swapped them out before the contest started and they seemed to tune up just fine, providing about 500W out on all bands with 80w of drive.  I ran the whole contest with this setup.

The conditions were not very good until around local grey line when EU started coming in on 40m and 20m.  Up until then, I was working almost exclusively NA stations which is pretty boring for a DX contest!  Operations were pretty tame and according to N5EIL, the Reverse Beacon Network was reporting only 800 some unique calls operating in the contest which is pretty small number.  None-the-less, I really enjoyed operating with the amp and the new antenna and got about 73,000 points from 440 contacts.  I'm really finding this Gap Titan to work really well on 40, filling in several slots for DXCC on the band.  Until now, I've never had a decent 40m antenna.  Even the dipole I had up in Iowa was too short for any effective operation on the band.  

The only thing that bugged me during the contest was the louder-than-ever AC cooling fan in the SB-200.  Sunday I decided I'd look at fixing it.  It's pretty trivial to remove the fan, just remember to shut the power off and let the amp sit for a while to bleed off the HV.  I took the fan out, oiled it a bit and put it back but in all that, I actually made the fan louder.  I needed a better solution.  I ran to Fry's and picked up a few 80mm 12v computer fans and set to wiring them in.  The easiest way to get 12v DC in the amp is to tap off the filament voltage (6.3v AC) and rectify it. (see image below) I used double sided foam tape to stick the fans on the inside of the tube chamber where the old fan sat and ran the wires through the mounting holes for the old fan.  I hooked up the rectifier on the bottom of the chassis and measured about 15v DC on the output.  Looks like I'll be over-volting the fans a bit but I have spares so if they fail, no big deal.  
Read more about the DC fan and other mods at PA0FRI's SB-200 page
Keep in mind, in order to measure all this stuff I've had to move the amp to the operating position, plug it in, and power it on.  There are LETHAL voltages present inside the cabinet.  I had the fans hooked up and they were spinning.  They were very quiet.  I thought, "hmm how much air is moving now?" and made the (nearly) fatal mistake of sticking my hand inside the chassis to feel the air flow.  I must have let my finger hit the filament clip (+2,500V) because in a moment I saw a flash of plasma, the undeniable sound of arcing, and that scent of lightly burnt flesh.  My left arm went numb for about 10 seconds but I walked away from that incident with a few 2nd degree burns on my middle, and index fingers, and my thumb.  BE CAREFUL AROUND HIGH VOLTAGE!!!  

I almost didn't want to share this bit because it's probably the most stupid thing I have ever done but maybe my tale can help keep someone else from making the same mistake.  

After I left things for a couple hours to nurse my hand (and my mind) I went back (with proper precaution) and luckily the amp survived the event.  I put the Centron tubes back in and buttoned everything up, applied power, and was happy to see that the amp had not been destroyed.  The breakers had tripped which probably prevented the whole thing from being far worse.  Even more, I was happy to see that the Centron tubes were working far better than the Svetlana ones, providing 100w more output on all bands, at half the grid current, which meant I could drive the amp with 100w instead of 80w.  Looks like the NIB tubes will go back on the shelf for backup.  I let the amp sit for an hour or so and I was very pleased with the reduced noise - the amp is no louder than my computer fans now - and cooling performance.  With the old fan, the top of the case would be quite warm to the touch, even when idling and now its only a few degrees over ambient. 

The last thing to do before everything is perfect is to figure out how to keep the room cool.  During the contest, my shack got up to 85 F quite a few times while the rest of the house was in 79 F range.  Unfortunately the only thermostat in the house is in the bedroom, on the other end of the house.  Running the furnace fan helps some but I think I need to balance the vents some more to make it really effective.  Just new house things I guess!

FT8 Dominates VHF Contests

By: Bob K0NR
30 July 2023 at 20:04

The FT8 mode was first released as part of the WSJT-X software in 2017. This new digital mode was adopted relatively quickly and is now a major force in amateur radio. You’ve probably heard the praises and complaints about it. On the plus side, it enables radio contacts under very poor conditions while detractors say that it is not real ham radio because the computer is making the contact. FT8 is an excellent example of a disruptive technology, impacting daily ham radio operations. This summer, I had two operating experiences (VHF contests) that really drove this point home.

My temporary station setup on the porch for the VHF contest.

ARRL June Contest

In the ARRL June Contest, we had very good sporadic-e propagation on 6 meters (and even 2 meters). I used my IC-7610 for 6 meters and usually had one receiver listening on the SSB calling frequency and the other sitting on the FT8 frequency. My strategy was to operate FT8 while keeping an ear on the SSB portion of the band. If signals were present on SSB, I switched over to that mode. The idea is that the run rate on SSB is inherently faster (and more fun), so it is my preferred way to make contacts. 

There was definitely activity on the SSB portion of the band, but it came and went throughout the contest. There were times that I was able to run on a frequency, calling CQ and having a steady stream of stations to work. Other times, I had to search and pounce, tuning around the band to find a new station to work. The FT8 story was different: most of the time there was consistent activity and new stations to work, but at a slower rate.

The FT8 operators tended to stay on FT8, even when the signals were strong. If they wanted to maximize their score, they probably should have switched over to SSB to make contacts at a faster rate. But they didn’t and that is their choice. (One thing I’ve come to accept is that I don’t control the choices that other radio hams make in terms of operating mode and band.) On 6 meters, I made 428 contacts with 80% of them on FT8. Radio operator decisions affect the types of QSOs made and if I focused only on SSB, I would surely have had more SSB contacts (but how many?)

CQ WW VHF Contest

In July, the CQ Worldwide VHF Contest was even more striking. While I was hoping for a repeat of the band conditions from June, the CQ WW conditions were not very good. However, I did manage to make QSOs using FT8 on 6 meters. The run rate was low and I often struggled to complete the exchange before the band shifted. Again, I listened on 6m SSB and picked up contacts there whenever possible. My QSO total for 6m was 164, with 90% of them via FT8.

After the contest, I heard from contesters that used only analog modes (SSB and CW) who reported that the contest was a complete bust. Even with hours of operating time, some folks only made 10 or 20 QSOs. This clearly tees up the choice: if you don’t want to work digital, you can severely limit your number of contacts. On the other hand, if you use FT8, you can make contacts under weak conditions, but at a slower rate with a computer in the loop.

Like many contesters, I would much rather have a nice run of QSOs on SSB filling up my log. It is just way more fun than sitting there watching the computer screen report the slow progress of FT8. But in the end, we all have the same choice when conditions are poor: actually making contacts using FT8 or sitting there hoping that band conditions improve enough to support SSB.

2 Meter Band

I did make some FT8 contacts on 2 meters, but found only a small number of operators using that mode. I expect that FT8 activity will increase on that band as people figure out they can squeeze out a few more contacts & grids using that mode.

New year, New Goals

 Well happy 2021 everyone! (I know I'm a month late 😂) 

January started off with another meeting of KY4ARC via Zoom. I finally sent in my dues so I should now be a member.

This year I decided to set a goal of participating in as many contests as I can. I started off this month with the North American QSO Party, SSB. I didn't have as much time to operate as I originally expected. After operating for about 2 hours I only ended up with 15 QSOs. Noise seemed to really bad on 40m. 80 meters was a little better, though I had some trouble breaking through the pileups. Of the 15 QSOs 13 were on 80 meters and 2 were on 40 meters. Overall all I had 12 multipliers for a total score of 180. 

Winter Field day was supposed to be my next contest, but thanks to a power outage the Friday before the start of the event my main shack computer shutdown and now fails to boot. So my logging and digital software were inaccessible. It's been on it's last leg for quite a while. It desperately needs to be replaced. I'll eventually finalize a parts list and start purchasing parts to build a new more powerful computer for the shack. Until then I'm going to try and nurse the current one back to health.

Other than a couple of DX FT8 contacts earlier in the month that is about all I've done radio wise. I did manage to make a contact with South Africa I think that's my first. I may send out a couple of QSL cards to stations from the NAQP. I haven't sent any out in a while.


Well that's all for now. Hope to catch ya' down the log!

Busy, Busy August

 Well not a lot has been going on radio wise the last month, except for a few FT8 QSOs here and there. I started an EMT class on the 17th that has been keeping me pretty busy! I may start trying to chat a little on my way to Ashland every now and then.


I've been working on updating the firmware and codeplugs on my radios (some were long overdue!). I've added a few repeaters to my Anytone 878, including a couple of DMR repeaters near Ashland that I didn't know were there (I still need to add them to the CS 800D in the car). Now I just need to use them!  


I think the last of my QSL cards for the 13 Colonies Event came in. All of them should now be viewable in the QSL Archive. My Certificate came in as well. It looks great! I'm thinking about framing my certificates with their QSL cards for each year, I think it would be nice to hang up!

In my last post I mentioned waiting for full results from the Kentucky QSO Party. Well they were finally posted. My final score of 3,036 points put me at 19 out 35 in my category (Single Op-Low), 24th out of 44 for just Single Op and 33rd out of 54 overall. Not bad for my first showing! Next year I hope to do even better.


I been thinking about adding another antenna to my setup. A simple dipole for 10m. I know a lot of people in my area talk on 10 pretty regularly so I'd like to have a dedicated antenna to use. I have everything (I think) I need to build one. Plus the pulley on my mast is empty since I moved the G5RV. I just need the time to get around to it! Eventually I'll add a 2nd G5RV but that's not an option right now.


One last thing: Please feel free to share my blog and website to someone who may be interested! 


Well that's all for now. Hopefully I'll have more for the next update!

2020 Field Day and More

Since the Kentucky QSO Party I stayed off the air for a bit until Field Day. My local club KY4ARC decided to do an at home field day with  1D stations submitting for the aggregate score. I operated for a
FD 2020 Worked Sections
FD 2020 Worked Sections
few hours and managed 32 contacts, all digital either FT8 or FT4. I was quite a struggle to say the least. I could not break through any pileups on SSB. I was able to receive the W1AW bulletin on 40m PSK31, my first attempt at trying PSK, I'll eventually get around to trying to transmit and make a few contacts.

In other new I was able to move from my apartment and now have all of my equipment in (mostly) one place! Over the next few days I'll be setting up some of the stuff I brought back so that I can hopefully use the local repeaters via RF.


I tried to work the 13 Colonies event for the second time but seemed to struggle a little (Even with a better radio/antenna setup). I ended up with 10 of the colony stations total. I worked all but K2I on FT8 (8 on 40 & 1 on 80). I managed to K2I in the last 20 minutes on 40 SSB in some of the worst noise I've had on the band. My received report was a 22, I sent a 33, but at least Andrea, K2EZ was able to pull me out of the noise!  I missed both of bonus stations and the stations in VA, RI, and DE. It's a little disappointing considering last year I had a clean sweep plus 2 of the 3 bonus stations (there was one less this year). I've already sent off for my certificate and QSL cards from the stations I did work.

I was finally able to make a QSO with Hawaii (actually two). Hawaii has eluded me since I started working HF, even from W8CUL. I worked WH6S on 20m FT8 and WH6HI on 40m FT4. Not bad considering I usually can't even receive them when they're spotted.

A few more awards from the FT8DMC were earned since my last post. Including another Worked All Continents award, this time with a 20m endorsement and a Worked Region 2 Silver. You can view all of the awards on the Awards page of my website. In addition to the awards I also uploaded 3 new QSL cards to the QSL Archive (including a K2I card from last years 13 colonies event). 


 


I've also been doing a little work on DMR hotspot. I tried to update it and instead I seem to have corrupted it (Oops!). So I had to re-re-flash the SD card. It seems to be working. I'd like to upgrade to a full-duplex hotspot for home and just use my simplex version for travel. But that's something for later.

My adventure of learning CW came to a stop almost as soon as it started after getting busy. I need to pick it back up. Hopefully soon!

My main desktop is still down and out. I need to start getting parts and build my new one. My laptop with an external monitor will do for now, but I miss the big computer!

I also found out that the Central KY Hamfest and the KY state convention were cancelled. I was hoping to attend at least the one of them this year. But I'll add both to my calendar for next year!

That's all for now.

Hope to catch you down the log!

And remember to wear the damn mask!!

May blog in June....KY QSO Party plus AUSTRALIA??

So I decided to hold off on the may blog until after the Kentucky QSO Party so I could share my score (and a few other things).

May was pretty quiet overall with not much going on ham radio wise.

I attended the virtual Contest University. It was a great event, plus you can't beat FREE!! I learned quite a bit from the different presenters. I think my favorite presentations were "Grounding & Bonding for Contest Stations" by the one and only Ward Silver (N0AX) and "Digital Contesting Hints & Kinks" by Ed Muns (W0KY). I figured out a few things I need to do for grounding whenever I get around to it. 

I also graduated from WVU! It wasn't how I planned it or with the degree I originally intended to get, but I'm  glad to have actually finished a degree!
KN4CFI KYQP N3FJP Summary
KN4CFI KYQP 

June started off with the Kentucky QSO Party. I operated from Lawrence County (LAW). I didn't do as well as I had originally hoped, but I'm still proud of my efforts. I ended up with 66 QSOs in 53 minutes total operating time. All were phone on 40 meters. I didn't do any hunting I decided to just work a frequency (or two). The 66 contacts plus 24 multipliers gave me a final score of 1,584. Overall, not bad for my first time!

The second week of June was really exciting. I FINALLY made my first QSO with AUSTRALIA!!! I've been looking for them for a while but never seemed to be able to receive them until now anyway! I couldn't sleep so I decided to work some FT8 & FT4 on 40m. I had pretty good luck with DX stations
VK7AC FT8 Contact
VK7AC FT8 Contact
right off the bat working Spain, Panama, Barbados, Anguilla, Argentina, Belize, and the US Virgin Islands. Before working AUS I saw a New Zealand station pop up in WSJT-X. I tried to work him several times but even though PSK Reporter showed a few NZ stations were receiving my I never could get a QSO. I was getting ready to shut everything down and go to bed when I saw a couple VK stations popping up. After trying a few time VK7AC, Norm in Tasmania, finally came back to me!! I almost fell over!! 
VK7AC LoTW Confirmation

The contact was made using WSJT-X (FT8), an IC-7300, and my G5RV. Based off of my calculations from Lawrence Co. (EM88na) to Tasmania (QE38mp) is roughly 9,867 miles (15,787 km)! It's already confirmed on LoTW too!!

With the confirmed contact in Australia I was able to apply for QRZ's Worked All Continents award. It was granted with an endorsement for Digital Mixed. I also applied for a couple of other awards from the FT8 Digital Mode Club.

  


Now to see what the rest of June holds!

Busy February...so far

Boy oh boy February has been busy. The first round of exams have started and a few class projects are starting to pick up. With all that my free time to play on the radio has substantially decreased.

I've had to put aside a few of my projects as my main PC's motherboard decided to fail. I've had plans to build a new more powerful, more capable PC for a while, I just didn't expect to start on it this soon. I'm going to be slowly buying the parts I need. I'll hopefully finish the build around March.

On the radio side of things my setup is a bit different. I'm using my Icom IC-7300 with an LDG AT-200ProII auto tuner. I'm also not using my Buddistick vertical any more, I've switched over to a hamstick dipole setup for 40m and 20m. It seems to work ok, but with all the interference around the apartment complex it still isn't going to work as well as I would like.

WVUARC is still going. We had our first meeting of the semester on January 30th. Attendance was pretty low, but it seems like other clubs on campus have been having that issue as well. We had a great presentation by ARRL WV Section Manager Dan Ringer, K8WV. He even donated a bunch of books to the new W8CUL Reference Library!

W8CUL was supposed to operate in the ARRL School Club Roundup, but of course something had to break. The fuse in our rotor controller blew, and it just had to be one that we didn't have a spare for. So, we only made two contacts. We'll eventually operate in a contest and do well!
Teaching @ WVUARC Tech In A Day (N8MDC Photo)

On February 15th WVUARC hosted our first Tech In A Day class. We had 19 people attend the full class. Of the 19, 11 passed their tech test. Overall we had 24 people take tests, of those 12 passed tech and one person upgraded to Extra! We ended up administering 49 tests. I actually had to close registration for the event, that's never happened before! I ended up running out of tech tests, thanks to a couple no shows I had just enough for the people who were there! We're already working on planning for the second one on April 18th.

In other news I got approved for three awards from the FT8 Digital mode club. I qualified for the
Worked Grid Award-100 for making contacts in 100 different grid squares. The next award was the
Worked Region 2 Award-Bronze for making contacts with 10 hams in region 2. The last award is the Worked Prefix Award for making contacts with 100 hams all of whom have different callsign prefixes.

I also got an award from QRZ.com. I got their Grid Squared Award for having confirmed contacts in 100 different grid squares. It goes nicely with the World Radio Friendship Awards (20m Mixed/20m Digital) I already had. I need to order my certificates.

I've decided to organize my QSL cards into a binder with photo pages of sorts. I also want to put all of my  awards in there, at least until I have a permanent shack and can hang them on the wall.

On the Website I've updated the equipment lists and added an awards section to the logbook page. I might redo a little bit of the formatting. I think I still need to scan at least one QSL card and add it to the album on the site.

I think that is enough of an update for now!

See ya down the log!

WACOM Hamfest, TIAD, ARES, and More!

It's been a month since my last post and quite a lot has gone on since then.


W8CUL participated in the ARRL School Club roundup in October. We didn't have as good of showing as I hoped for, but with only two people operating we still did pretty decent with about 3 hours of operating time and 50ish QSOs we did better than 11 during the spring SCR!


WVUARC also hosted our second Tech-In-A-Day class of the semester. We had about 8 people take the course. Of those 8 we had 6 successfully pass the Technician test. Two members of the club also upgraded from General to Extra!


I completed some ARES training this weekend as well. I took my final exam for the ARRL's ECC-001 Intro to Emergency Communication course. This course was the only thing I needed to finish all of the requirements for ARES Level 2!

ECC-001 Certificate

I made the drive up to Washington, PA on Sunday for the WACOM hamfest. Overall it was a decent hamfest, though attendance seemed lower and prices seemed higher compared to last year. I ended up grabbing a pair of QuickStick hamsticks from Quicksilver Radio. I grabbed one for 20m and one for 40m. I also bought a 5in magnet mount for the hamsticks (to use while stationary). Unfortunately there is a short in the power cord for my IC-706 so I did't get to try out my antennas yet.

I also found a Heil HTH-K headset for my HT. My last purchase was a pair of old boxes that were used for TV and radio repair. I thought they were a pretty cool find!

Well, that's all until next time!

See you down then log!
