This project is a collection of former (and some new) projects connected together to make an APRS digipeater, which doubles as an APRS weather station, with PE1RXF telemetry server capabilities.
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
