|Etch A TV is currently a work in progress. The code in this repo is horrible and is closer to a proof of concept than something that can be easily maintained.|
Etch A TV is a simple modem that uses two tones to represent an X and Y coordinate. This allows drawing simple images over radio. It's designed for ham radio use over 3khz SSB.
pip3 install etch_a_tv
If rigctld is listening etch_a_tv will use it to control PTT
rigctld -v & etch_a_tv
