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 recently got the RSP1A (SDRplay). Connected with a (low-pitched) discone. I'm satisfied. My goals are to raise the mast & an HF antenna. (Of course, several peaked antennas will follow in the future. Such as the 2 meter, 70 cm.)

But a customs bill as a surprise? Very annoying ☹️

Oh look, mastodon.radio is a year old!

I posted the first toot here a year ago yesterday.


I guess you that know masto has taken off when you get spammy follows!

I'm not sure if this was the result of some sort of rift, but 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.

Wait, what is that?



Did you always want to use Toot!, but did it just not look MANLY ENOUGH?

You can now buy Toot! for Men as an in-app purchase! You're a man, you can afford it!

You will get the all-new and entirely testosterone-fuelled TACTICOOL THEME:

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.

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.

Happy to all my follow instance admins, moderators, and everyone else who keeps the fediverse running!


WSJT-X 2.1.0 has been released:


The main addition is the FT4 mode, but quoting the release message:

Improvements have also been made in the following areas:

- FT8 waveform generation using GMSK, fully backward compatible
- user options for low-sidelobe waterfall and spectrum display
- UDP messaging for inter-program communication
- accessibility

... as well as many minor enhancements and bug fixes.

Release notes at: physics.princeton.edu/pulsar/k

"The Antuino is an Antenna Analyzer and a compact RF lab for the homebrewers"

This look cool, I like the big control knob: hfsignals.com/index.php/antuin

Here's the RSGB's statement on the 2m WRC process:


tl;dr: please don't sign any random badly worded petitions, we're on it.

I think (as others have said) continuing to pay the RSGB for membership is probably the best course of action for now.

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 (uk.pi-supply.com/collections/p 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: rfzero.net/

Cost is ~£60, so not bad.
