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 ☹️
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.
This looks like a decent Kicad tutorial: https://github.com/MalphasWats/hawk (seen via hackaday https://hackaday.com/2019/07/29/a-new-kicad-tutorial-hits-the-scene/ A New KiCAD Tutorial Hits the Scene)
This is an interesting read:
Exploring The Raspberry Pi 4 USB-C Issue In-Depth
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
... as well as many minor enhancements and bug fixes.

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.
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.
