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

Hi Octopeeps... Is it possible to rename cars in the devices part of the Octopus App? I would like to tell these two cars apart... Thanks. @OctopusEnergy

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 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

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: george-smart.co.uk/2026/08/a… #hamradio #homebrew #antenna #elecraft

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

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

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.

Today @m0wut 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

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

Tonight's activation of #POTA GB-2325 was fun as I had a sked with Jon GW2HFR on #SOTA GW/NW-047. I total, 26 in the log: a mix of CW and SSB on 40m with 2 bonus contacts on 15m when I called thinking the band was dead! 😂 Thanks to those OPs who follow me here, too! #hamradio

A long day today (Sunday) to make up for feeling unwell yesterday. Managed to activate 7 #SOTA summits today, all in G/WB. Made a bit more tricky by SOTA servers being flaky, but we got there! Thanks to all those who chased! Enjoy some random pictures from the day! #hamradio – at Fordham, England

I managed a couple of #SOTA today, G/WB-010 and G/WB-015. I had a lot more planned but felt quite unwell after lunch! No takers on 2m CW. Decent activity on HF, as expected on the weekend. Let's see what tomorrow had in store! – at Priorslee, England

Todays #POTA activation was at GB-4807. I activated with my mcHF, homemade in 2015, on the higher HF bands with 10W CW. A added bonus was meeting up with Thomas K4SWL (M5SWL with his UK call), as well as Bob M6BOB. #hamradio

First time out portable in a couple of weeks and my CW felt rusty! Still, managed to get 27 QSOs in the log in an hour. Nice mix of EU and US. #pota GB-2325 #hamradio
