6m DX the week of June 7 2021

 6m here in FN42la was somewhat dead for 6 days in a row, which is somewhat unusual for the month of June. The previous big opening here was on June 4, which I talked about in my blog post "Another big US-EU opening 2021 June 4." 

Finally, on June 11th, we started to see some signs of life, including some DX excitement. I was decoding TZ4AM in Mali, but he wasn't hearing me. Still, very exciting:


Next up, as I previously mentioned was S01WS in Western Sahara. I managed to get a single sequence back from him, but never got 73's, so I logged it but didn't expect it to be valid. 




Luckily, I was able to work him again on Sunday June 13th. The propagation path was very specific, it was hitting the Azores and the Canaries, with a little bit of southern Spain, then mainland Africa. 





Meanwhile, in the other direction it was wide open, including some double-hop to the west.

Busy June 2021 contest weekend

 This was a busy radio weekend. First, the N4EME crew set up in rare grid FN57 in Northern Maine. I tried with them on FT8 on Friday night but wasn't successful. The next morning I got on the chat server and saw they were working folk on 6m meteor-scatter, MSK144 on 50.260. I don't have a lot of meteor scatter experience, but I gave it a shot an was decoding them on pretty regular pings. I was able to quickly work them and then focus on getting ready for the ARRL June VHF contest. 

The June Contest is usually dominated by 6m activity, and now with FT8, that can make it somewhat boring. I love operating 6m FT8, but it's not super fun during a contest. I find there are soo many people on that I have a hard time completing contacts. So, off we went and of course, we ended up having a massive opening to the Caribbean, which normally is great, but a lot of times the DX stations aren't running in contest mode, so you have to either switch WSJT-X out of contest mode or run JTDX at the same time (Which is what I did). In the end I worked number of the DX stations, including:

TO11A - Guadalupe

PJ2BR - Curacao

VP9NM - Bermuda

HK3O - Colombia

PJ4NX - Bonaire

HK3W - Colombia

9Y4D - Trinidad and Tobago

8P2K - Barbados

J79WTA - Dominica

PV8DX - Brazil

NP3YL - Puerto Rico

I had recently been complaining that we hadn't had much activity in the Caribbean this season, but this list seems to say otherwise. 

The big DX news for the weekend happened further to the north. I was able to work Bo, OX3LX, who is operating in Greenland. Bo has been there since the previous Tuesday, but I hadn't been able to hear him at all. We finally got the opening during the contest and I was able to grab him before he had a big pileup. 

After that the other DX was Western Sahara in Africa, S01WS. I've been seeing other folks work him on and off for a while, and I've occasionally had a few decodes from him, but again, was finally able to work him. I had a busted QSO earlier in the week, this times I was able to confirm it. 

The contest was a low priority effort for me. My main goal was to get my voice capabilities working again for 6m, which I was successful at doing. Calling CQ on 6m SSB was a lot more fun than operating FT8, and it produced a number of contacts, faster than digital. 

The end result was about 14k points

 Band   Mode  QSOs     Pts  Grd  Pt/Q
    50  FT4     17      17    8   1.0
    50  FT8     47      47   36   1.0
    50  USB     54      54   31   1.0
   144  FT8     20      20    9   1.0
   144  USB      5       5    3   1.0
   420  USB      7      14    6   2.0
 Total  Both   150     157   93   1.0
Score: 14,601

DXCC on 17m Digital!

 As a follow-up to my previous post, 100 DXCC entities in 33 days, I finally confirmed my 100th country on 17m!




I have 119 entities worked since 1/1/2021, that's a decent QSL rate. 

Ok, what band is next?

2020 ARRL September VHF Contest

 I didn't really have time to do much operating this weekend, Saturday was Soccer game and kid stuff. Later in the afternoon I got for a bit and tried to get 222 and 432 running. I somehow ended up blowing my 222 Amp. I had it outputting 300W and the next thing I know, it was down to zero watts. I probably blew the FET, new ones appear to be around $100, if i'm lucky. After further troubleshooting, the SWR on my 222 antenna is up over 5:1, which the FET didn't like. 

Sunday afternoon I managed to cobble 432 back on the air and worked a couple of mostly local stations, with the exception of WB1GQR in FN33, Vermont, but they usually are on a mountaintop. My 432 is only a 6 foot book and it's basically pointing right into trees. Anyhow, 50w and a few contacts. 

I have better 432 and 222 antennas on the ground waiting to go up, I'm waiting for the weather to get a little cooler. With luck, everything will be working for January. 

Band conditions didn't seem very good. I tried with VE1SKY in FN74, he was hearing me, but I didn't hear him at all. Better luck in January.  

Final Score: 2,312

6m:  21q 13g

2m: 27q 13g

222: 1q 1g

432: 9q 7g


Best DX: 

To the North: 2m VE2PN in Quebec, FN46

To the South: 6m K1HTV in VA, FM18

Dayton 2012

I just got back from my annual pilgrimage to Dayton, Ohio, for Hamvention 2012. I flew in on Thursday and spent the afternoon with a few friends at the USAF Museum at Wright-Patterson AFB. If you have never been, this museum is fantastic and never gets old. This year they added some recently declassified spy satellites!

We were blessed with good weather this year, if not almost too hot! Not a single cloud either Friday or Saturday, both days were in the upper 80's.

There was lots of good junk for sale, but the only major purchase I made was a Tektronix 2465 scope. I happen to be hanging out with a scope aficionado and he gave me the pros and cons of the 2465. It sounded well within my level of risk and I managed to find one for fairly short money. I have to give a lot of credit to Alan, W2AEW, for influencing me on making this purchase. I've been watching his Youtube channel, he has some really great videos on how to use your scope. He has a 2465 and I've fallen in love with it while watching his demos.  

Stay tuned for another update on my PCB design.

10 GHz Contest, Weekend #1


The first weekend of the ARRL 10GHz Cumulative Contest was last weekend, the 15th and 16th of August. I had really desired to be a little more organised this year in an effort to increase my score over previous years. I managed (or so I thought) to get all the gremlins out of my equipment, and even had enough spare time beforehand to put together a spreadsheet of all the operators who planned on going out for the first weekend, their locations, and their mobile phone numbers. I was far too organised for this to be a smoothe weekend :)

First stop, I planned on being at Mt. Kearsarge from the time the gate opens (9:30a) to closing (6pm). I hadn't even made it to the gate when I realised that I forgot the antenna mast for the 2m ssb antenna. Hrm...well, there is a hardware store down the street from the mountain, I'm sure I could find something there. I did, a 5' 1.5" wooden dowell would do the trick. Thankfully I had a roll of gaffers tape with me to secure the antenna down. Ok, problem solved, off to the mountain! Next problem, they are painting the yellow lines on the road to Kearsarge. Ok, a few minute delay, not a big deal. Well, I get to the gate and the woman tells me I have yellow road paint all over the drivers side of my car and in the wheel well. GRRRR! I didn't drive over the line, just all the arosal they use to spray the lines collected via the vaccum action of the car. Luckily that will come off, with some elbow grease. I noticed the first 3-4 cars up on the mountain all had the same problem.

On to the mountain! I get set up fairly quickly and start to have a normal day contesting, but it was HOT! I had plenty of water with me, but I was getting baked. I had tried using this bugsparay/sunscreen that was on sale at CVS, but It clearly didn't work for either purpose. I got eaten alive and burned to a crisp. I'm not really complaining about that, it happens every year, I've learned to just deal with it. About noon time I start having a re-occuring issue with my rig, the main T/R relay isnt' switching when I'm transmitting. That means I'm putting 8 watts into a relay that isn't terminated! I figured out that it was my sequencer board, one of the relay contacts was intermittent due to a bad solder joint. I found that if I put pressure on the relay it would switch. I could continue the rest of the day like that and fix it at the hotel.....had I not broken a wire of the sequencer board while troubleshooting. D'OH!!! Well, off to Radio Shack I go. There has to be a Radio Shack here in town, right? WRONG! The closest I could find was 40 minutes away. Off I go.....

(Note to self: When packing the night before a contest rover trip, if you have the soldering iron in your hand and say to yourself "Nah, I won't need this"....ignore the inner voice, take it with you)

I finally get to the destination, only to discover this store is about as small as I've ever seen. I kept thinking "there's NO way they sell soldeing irons, I'm screwed". But, I asked the woman behind the counter and was shocked to find that they had no less than 5 types of irons and 8-10 types of solder! I take back all those bad things about Radio Shack over the years, they saved my bacon this day!



Now, here I am in a Rat Shack parking lot, the back of my car open, inverter running, soldering iron getting hot. In about 15 minutes I have the fixes in place and it seems to be working......Ok, back to the mountain.

After some mid-day traffic and a lunch break, I make it back to the mountain around 3pm to find Byron, N1EKV, making some contacts. I pull in next to him and get set back up. The rest of the day was fine, but they relay problem wasn't 100% fixed, there was something still wrong.

I managed to make 22 contacts at Kearsarge, which was the most I've ever made there (17 the previous year). I can only imagine I would have snagged a few more had I not made a 3 hour detour. I was the first person up the mountain, and I was the last one down (As the park ranger sat, staring at her watch). Now, on to my long haul to Gorham, NH at the no-tell Motel.

I had booked this room at an amazingly cheap rate of $50 a night. Afterwards I saw some really horrible reviews online. I expected the worse, but was pleasantly surprised. Everything was clean, no worries. So, I dragged the battery, battery charger and Microwave rig in and got to work. As it turns out, my parking lot soldering session was mis-guided. I completely missed the bad solder joint, but re-flowed a number of working joints :) I re-flowed the bad joint, and I finally fixed the problem. I got a good nights rest and was up at the crack of dawn to be at the gate at the Mt. Washington auto road at 7:30am.

Oh...my....lord....the Mt. Washington Auto Road has got to be about the scariest drive you can make in a car. I've driven to the top of Pike's Peak (14,110ft) a number of times, but that was cake compared to this road. There was one point that I wasn't sure I was going to make it :) My fear of heights was in full swing, my knuckles were as white as ever.....but I made it.

I met N1JEZ, W1AIM and K1LPS at the mountain. We grouped together and had a really great day on Washington. Some of the highlights were working WA2FGK in Fn31bf at over 500 kilometers, VE3FN in both FN14 and FN15, and VE2JWH in nearby FN45 and FN46. All in all, I made 33 contacts in 12 grids. 12 grids in one day!!



It was a long, exhausting ride home, but well worth it. I'm alreadying hatching plans for the second weekend. Look for me on Saturday roving on Cape Cod. I'm likely going to be at 4 locations, including Marconi Station, FN51av. Sunday isn't planned yet, but I may look at doing a CT/RI/MA costal run for three spots. Tune in for more details!
