For anyone who's into APRS, I've been working on a modern alternative called CATS for a few months: https://cats.radio/
It cleans up the bloat in the protocol. Packets are modular, consisting of whiskers, which can be mixed and matched depending on what you want to convey in your packet.
Everything from the physical layer up has been completely revamped. We're running raw FSK for a massive 12dB coding gain over AFSK. Modern commercial transceiver chips makes it economical to do everything in FSK. These didn't exist when APRS was first developed.
We're also using LDPC for forward error correction, and have boosted the data rate from 1200 baud (APRS) to 9600 baud.
I've developed reference implementations of a Raspberry Pi I-Gate and mobile transceiver. Both are fully FOSS, and I'll also be selling units fairly shortly for $24 USD and $49 USD respectively.
But that's all just a summary. I highly recommend checking out our site for more information! https://cats.radio

What name do you like best for a non-profit #FOSS community for Ham Radio? Think Apache incubator but for Ham plus other open-source services and resources for the community.
FYI I have both the dot com and dot org as well as the hyphenated and non hyphenated versions of the below. Please mention which variant you prefer in comments.
