CATS I-Gate boards are back in stock! (And my wrists are sore from snapping off PCB edges)

First 2-way inter-provincial CATS messages. #hamCATS

CATS, in the palm of your hand! Spent this weekend writing a GUI library that I can use to develop the rest of the software. Just the textbox alone took hours - so many edge-cases and I had to rewrite a lot of stuff. Definitely has some rough edges I still need to fix.

There are other issues - the screen refresh rate is slower than I'd like - but not bad for a bit of free time this weekend. #hamCATS #CATSradio

Got CATS running on a DFM-17 radiosonde. Still needs some work, mainly cleanup, but the hard stuff is done! The packets are generated entirely in software - no hard-coding shenanigans!

I've been working on a handheld CATS transceiver, called the CATS Companion. My LCD screen died, so while I wait for a new one, I spent the weekend designing a case for it! #hamCATS #CATSradio

For those following CATS, I've written an RX I-Gate that receives packets from an RTL-SDR and forwards them to FELINET.

It uses the codec2 FSK demodulator, and does soft-bit decoding under the hood so it should be operating close to the theoretical limit of what's possible.

I do still prefer a "real" I-Gate (that is, one that can transmit), but in a pinch, an RX I-Gate is certainly better than nothing!

This is what CATS development looks like. Squashed two bugs today, neither of which I realized existed!
