Repeater Systems

Amateur radio repeaters can be linked together into a repeater system. When you send a transmission to any repeater in the system, your transmission is relayed to all of the other repeaters in the system. I've gathered data for 14 repeater systems in the Mountain West. Each one has a map, frequency listings, a printable list, and a file you can download and import into CHIRP.

APRS Service Registry

APRS services, sometimes called bots, provide useful capabilities to operators via APRS messages.

I've been keeping my own personal list of useful bots and what their commands are. I'm throwing away my list.

Craig KM6LYW introduced me to the APRS Service Registry. The registry is much larger than my list, and has the benefit of being a resource for the entire community.

Proposing APRS On The Air

I have a proposal for a new APRS activity and supporting software called APRS On The Air. It brings the activator-and-chaser game of Parks on the Air and Summits on the Air to APRS.

Read the proposal at https://aprsota.org. I'm looking for feedback before I build the software.
