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.

It's Alex! A soft brown mastodon holding a handheld radio in their right hand and carrying a blue bag over their shoulder

Finally got my Pi synced to the PPS pin on the GPS I plugged into it. It’s currently indoors with a small ceramic antenna, but works.

Software is gpsd and chrony, hardware is a cheap ublox board with a hirose u.fl connector and a patch antenna, soon to be replaced with a chinese outdoor antenna.

The Pi is a model b, configured to use the standard UART (ttyS0) not the better one (ttyACM0), but that might need to change.

I think it’ll be cool to add a little display with position/clock info.

Output of chronyc sources -v, showing various time sources. PPS0 is being used to set the system clock.

GPS information from a small python script. Included is time, latitude, longitude, maidenhead grid square a few other bits.

Our stall at Westrally was busy! Manning it was good fun and stopped me buying too much junk.

Most interest was in G0VFS’ paddles but nobody bought them 💁🏼‍♂️

A table at Westrally, various bits of radio equipment and junk adorn the tables.

A home made iambic more key. The base is marble and the key is brass.

Another home made key. This is straight with a glass base.

Looking forward to Westrally ( https://westrally.weebly.com/) tomorrow, in Frome.

I plan to help out on the T&DARC ( https://sites.google.com/view/tdarc/home) stall so it should be a fun day!

Had a lot of fun on the club’s fox hunt last night. It was my first, so I basically went to see how it worked. My team failed (mostly due to a lack of decent gear I reckon) but I will know what to do next time! First on the list is getting my tape measure antenna working.

Looking forward to it!

Whoops, that last but was supposed to be the image description. Not sure what I did there.

The RSGB has relaunched RadCom basics: https://www.rsgbshopping.org/public_html/acatalog/RadCom-Basics.html

For some reason they have done it using their crufty and ancient online store!

This double sideband TRX kit looks like fun, and not too expensive: https://www.dk9jc.de/blog/equipment/180-d4d-dsb-transceiver-kit-for-digital-mode-for-only-39-95

A bit like a useful version of the RSGB’s PSK receiver kit perhaps.

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.
