10 days after the last RC we have WSJT-X 2.4.0-rc3.

It looks like the changes are mainly bug fixes, and this release is focussed on Q65. I guess it's time to build more antennas!

Fediverse friends and followers from around the world, I have a huge favor to ask!

If you are out for a walk or drive and you spot a payphone, would you mind sending me a photo of it? (DMs are always open) I will feature it on my #100DaysOfPayphone thread over on the birdsite and of course give you credit.

When I started this a couple of weeks ago I didn't realize all of my old photos from before 2018 are gone, which means the hundreds of old phone photos I had taken at one point are also gone. But maybe this opens an opportunity to see payphones from around the globe.

This could be a payphone that you spot in the wild that still exists (thank God there are still some of those out there) or it could be a photo you took in the past of a phone that may or may not be there anymore. But please, let me see your payphones!

If you have photos of other cool phone equipment or phones that aren't payphones, they won't work for the #100DaysOfPayphones thread, but I encourage you to send them my way as well. Phone related stories? I'd love to hear them! Please help me spread this around the world!

All payphones are acceptable, but I especially encourage you to send in any photos you have of payphones from countries other than the US or phones that are unique in some way. Also, PLEASE boost this toot and help me get this call for help out there! Thank you! 📞

So ofcom is updating spectrum licenses to require that all stations comply with EMF exposure regulations because people are afraid of 5G and "electro-sensitivity" (TIL).

Here's my favourite bit of the latest consultation:

> Some, mainly confidential, respondents raised fears that 5G and other technologies could be used for surveillance and crowd control purposes.

At least the requirements will be fairly easy to comply with!

Essex Ham have produced a useful page giving brief details and links for online training courses for the Foundation, Intermediate and Full exams in the UK.

Hot off the press: WSJT-X 2.3.0-rc4 is out.

This is a "stop-gap" to verify some changes in hamlib, plus a few other small changes.

Someone (specifically Denis Grisak KW0X) out here designing a digital mode interface, and open source to boot!

Just reading about the Raspberry Pi Pico:

It's a microcontroller rather than a computer like the rest of the Pis but it seems super cheap compared to other similar products and it looks like it'll be well supported.

Has anyone here come across "C Connectors" aka MIL-STD-348 ( /

Dad has a dummy load which uses this sort of socket and I can't find parts! They look like really chunky BNC connectors, I'm assuming from the MIL code that it's ex-military from the US.

RSGB Tonight @ 8 - Amateur Radio Construction with Steve Hartley, G0FUW and Pete Juliano, N6QW

Steve G0FUW (GQRP chair and known for Bath distance learning in the UK) + Pete N6QW (homebrewer extraordinaire).

Should be interesting!

I always see more people out and about when I exercise during lockdown. Lots more (walking) pedestrians.

I think people must feel like ensuring they make use of what little time out they're allowed while their freedoms are curtailed, but why not consistently go for a lunch time wander?

The Morse key on the front of last month's RadCom ( was made by a member of my local club, Roy G0VFS talked about the build back in June and you can see the video here:
