CATS - Communication And Telemetry System

This looks like an interesting project in the ham space that aims to replace APRS with a more modern feature set. Check it out @ https://cats.radio/

I've now got a CATS I-Gate running at home with my APRS I-Gate on the same Raspberry PI and same antenna (using a duplexer). This works well because CATS is on UHF (430.500 MHz) and APRS is on VHF (144.360) so a cheap-ish duplexer (sometimes called diplexer) can be used. I got mine off Amazon (not an affiliate link).
