Here are the toots from my Mastodon account. If you’re into ham radio and technology this is a great inclusive server with an awesome mascot called Alex.
UK radio amateurs: how does licensing for portable repeaters work? Is it the same as for fixed repeaters?
I’m curious because some foundation license holders I know want to make a low power portable repeater using back to back HTs and I think they almost certainly aren’t allowed but I can’t find anything obvious in the license terms about it.

The back panel looks absolutely jam packed! And there will be a solderless kit!
→ View toot on mastodon.radioBeen busy with other stuff recently so not done much radio/electronics but I made this BNC patch cable for @2w0kpf last night.
Pretty pleased with how it turned out.
Crimp connectors are great once you get the hang of them!
Haha, someone tuned a bowl of Custard and made some FT8 QSOs: https://michaelcullen.name/2019/04/custard-antenna/

He’s using kapton tape stuck on a PCB as a heat-proof mask, then sticking copper tape on top of that to make interconnects.
This gem popped up on RSGBTech in the midst of a discussion of the current Amateur Radio exams! https://groups.io/login?r=%2Fg%2FRSGBTechnical%2Fmessage%2F48564

Presumably this is part of the switch away from monthly subs that some of us discussed here last year ( https://boldport.com/blog/2018/10/18/boldport-club-is-changing)

… and plenty of grumpy old man moaning already 😀
Not seen any “it’s not real radio” yet, but it’s only a matter of time.
→ View toot on mastodon.radioSpent a while yesterday receiving SSTV images on 20m (14.230 MHz), some pretty scary and really interesting.
I don’t think anyone would deny that it’s a pretty weird way to communicate, super fun though. Next I need to work out how to TX with qsstv (but first, family stuff)!
The website layout is a little confusing, but this SWR analyser and WSPR TX looks fun: http://jackdev23.wixsite.com/iw2ndh-swr-analyzer
Out of stock but usually ~ €50 plus shipping, so not bad!
I also keep seeing people mention http://sp3nyr.itserwer.pl/index.php/arduino-swr-scanner and N1201SA a lot too. Lots of interesting (low cost?) options based on lots of platforms.
