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.

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 💁🏼‍♂️

Looking forward to Westrally ( tomorrow, in Frome.

I plan to help out on the T&DARC ( stall so it should be a fun day!

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

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!

The RSGB has relaunched RadCom basics:

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

I highly recommend the Ham Radio & Electronics Stackoverflow weekly newsletters.

They bundle up the top questions each week and mail them out, which makes for a quick and easy way to learn a few interesting things.

This double sideband TRX kit looks like fun, and not too expensive:

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

(I don't remember where I found DK9JC's blog, but it's worth subscribing.)

The HAM @Hammut

Looking for a twinband T-antenna. In Rothammels antenna-book it is called Multee. Designed by W6BCX. Think it is more than 40 years old. I am looking for a simple solution for my 2-band QRP-TRX. It would be nice if hams from abroad would help me with internet sources. I haven't found any.

There's 15% off "Tech & Appliances" on eBay UK at the moment with a coupon code (PLUGIN15).

This includes the Radio Communication category!


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.

Interesting to see the news about the new SDR based Elecraft K4:

The back panel looks absolutely jam packed! And there will be a solderless kit!

Been 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!

Funniest thing I have seen today is this marketing video of a ... terminal, which emulates a 1970s teletype. An essential read:

And the video:

This looks like a cool way to prototype using SMD parts:

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!
