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

CloudFlare will respond to DNS lookups on 2m FM. Awesome!

The PiJuice zero looks nice. It’s a UPS/battery management HAT for Pi Zero:

This might be a fun way to make a mobile GPS based clock or maybe an APRS module, if it’s stackable with the boards @M0YNG has.

Pi Supply is a UK company, so I expect they’ll be available direct eventually for us brits ( https://uk.pi-supply.com/collections/pijuice has some larger HATs for full sized Pi boards), but the shipping cost seems fairly reasonable.

This “The RFzero™ board is an Arduino compatible GPS based Si5351A RF signal source” looks pretty cool: http://www.rfzero.net/

Cost is ~£60, so not bad.

Just read about this simple SDR in June’s QST mag: https://www.i2phd.org/armradio/index.html

What a neat (and small) project!

Ooh, just read that 2m crossed the Atlantic for the first time: https://rsgb.org/main/blog/news/gb2rs/headlines/2019/06/21/2m-crosses-the-atlantic/

Naturally, everybody’s favourite FT8 was involved 😀

Looking forward to reading more about this.

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.
