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.

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

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

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

https://rsgb.org/main/blog/front-page-news/2019/07/01/144-mhz-and-the-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:

https://www.crowdsupply.com/pi-supply/pijuice-zero/updates/the-pijuice-zero-campaign-is-now-live

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.
