I finally tracked down some QRM at home ahead of the 80m CC contest this evening. Turns out my OpenEVSE causes S9+10 of noise below 9 MHz, which drops to S4 when off! #hamradio #qrm #emi

Yeah. That was it. 😂 I was G3PYE. The grownups were all busy so I was allowed a go with the callsign! 😂

I got 95 in the log, but didn't call for long. 🙂 I operated alone. I didn't see you spotted on the cluster either? 🙁

Supposed to be good. @m0taz.bsky.social has one and is very pleased with it. I need something that can fit all the junk in it, and tow, etc., plus the charging network on long EU road trips keeps me going back to Tesla, though I did look at Mercs and a few others. Colleage just got Ionic 6N, too!

Snap. Also took delivery of a 76-plate EV a week or so back. Much fun. Now to sell my 2023 Tesla Model Y Performance. 💪

Nice! I'm now after the Kilo award, probably at The Devil's Dyke GB-2325.

@m1buu.bsky.social thanks for the QSOs with M0VFC and me earlier, we were out at field day, and trying not to cause too much QRM. Thanks for the complete for us both! 😂👌

A 2m FM only activation from #SOTA G/WB-009 (Worcestershire Beacon) in #POTA GB-0356 (Malvern Hills). I was planning HF CW and SSB but there were storms immenent and I could hear the static crackling on the tip of my RH770 antenna on the handheld. #hamradio

I have 3 factory made ones. 8Ah EcoWorthy, 20Ah UltraMax, and 300Ah Renology. I'd recommend them all, need depending.

Doesn't look like an EV? I'm told they're the ones that catch fire 😏

George Smart, M1GEO @m1geo.com · 15/08/2026
A day of #SOTA activations in G/WB, with a few bonus #POTA too! #hamradio Lots of familiar callsigns from here, too which was nice! Same again tomorrow!

Yes. It is. Working on it. It's a fault following a power cut blowing up some networking equipment.

I ended up also doing an ATNO activation of #POTA GB-5740 (with 85 in the log) and also GB-5597 (with 12 in the log) once John M0IDA departed, since the ATNO was on the way home, and the other was on the walk from the car to the forest. #hamradio #portable

Probably. Lol

I tried to find you on 40m but you were under someone stronger. But I did see you about. Most recently on 17m but the skip was wrong! 😂 We will have a QSO one day! 😂

George Smart, M1GEO @m1geo.com · 08/08/2026
Activated a few ATNO #POTA parks today with M0IDA. A mix of CW and SSB. #hamradio

Icom, why don't you put APRS into radios? It's just software! ID5200 has it on the feature list, pending software updates! It's the reason I love my Kenwood TH-D74E. Built in APRS and TNC.

For anyone interested in the homebrew loaded whip antenna (AX1 inspired) I posted about earlier, I've popped the design notes and files up here: www.george-smart.co.uk/2026/08/a-ho... #hamradio #homebrew #antenna #elecraft

It doesn't weigh much at all. And it can fall over (and did, often).

This evening I spent a couple of hours on the radio from Thetford Heath Nature Reserve (until they closed up), #POTA GB-0009. I had a great run on 20m CW, with lots of pileup practice and some nice DX. Great fun! I also had a blast on 40m SSB, but the band was noisy! #hamradio

Haha! It was very saddening to be getting reports if nice WX back home, as I trudged about in the rain. 🫤

George Smart, M1GEO @m1geo.com · 27/07/2026
A few additional pictures of #SOTA G/SP-001 Kinder Scout (I activated from Kinder Low trig point). The walk was nice, despite the WX.

On Sunday I activated three SOTA summits, G/SP-001, G/SP-015 and G/SP-013, along with their associated #POTA parks. WX was bleak, it rained all day, and was about 13C. But it was a good day! #hamradio #AmateurRadio

Today @m0wut.bsky.social and I activated #SOTA G/SP-004 and #POTA GB-6042 - Shining Tor. It was windy at the summit! As usual Elecraft KX2, at 10W CW on 40m dipole and Kenwood TH-D74E. #hamradio

Very nice! I need to get a decent 2m setup. I don't have the height for it.

Not at all! Nice!

Afternoon activation of #POTA GB-6686 was good fun, 27 contacts, 5 SSB and 22 CW. Got two #SOTA chases and six P2P. Mostly a wooded area with a busy clearing, so I stayed in the shade of the woods out of the way. Elecraft KX2, 10W, and MA-12 antenna. #hamradio

I had an alert for them on eBay for a while. Both KX2 and KX3. They do come up occasionally, but hold their price. I played around with one when I did a repair of a KX3 for M0VID. I then did a SOTA activation on 10m CW with Dave's KX3 and figured I needed one. bsky.app/profile/m1ge...
