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

Had a quick go with a mini whip antenna (in my loft) any my new HF+ discovery.

I powered it with a cheap lab PSU and the noise floor raised enormously from ~ -85 dB to -60 dB with regularly spaced carriers.

Definitely amplifying a load of crud from in my house and presumably the PSU isn’t helping!

I’m not sure if this was the result of some sort of rift, but https://groups.io/g/RSGB-Workshop looks like it might be an interesting group.

Also, unlike the RSGBTechnical group which (confusingly) isn’t anything to do with the RSGB, this looks to have been setup by one of the RadCom authors.

Got my Airspy HF+ Discovery!

Had to pay some fairly hefty import tax but this looks pretty nice.

Shame all the most user friendly and feature rich software is Windows only. I’d love SDR# for Linux or Mac.

Renewed my ARRL subscription and added QEX as it looks fun. Looking forward to yet another radio mag to read 😃

Got a copy of the new English translation of Rothammel’s antenna book.

What a beast this is! It has more in it than I would have thought possible and nearly 1600 pages.

The cover of Rothammel’s Antenna book. This is the first edition in English.

Had a fun morning at the Chippenham Radio Rally.

It was smaller than the others I’ve been to but it was my favourite so far in terms of stalls.

It was great to catch up with the GQRP/Bath Training guys who were there. But I wonder why my local club didn’t have a stall.
