APRS Telemetry Watcher is a simple, slick interface that connects (in my case) via a network connection to an RPi in my shack running dire wolf APRS software. APRS-TW looks for telemetry packets, then displays them in a nice graphical format.

It’s a simple piece of software, runs in a Windows environment, and the individual telemetry values, names, units, etc., can all be filled in the GUI so that the data that appears is already in engineering units. (i.e., instead of a telemetry value of “491”, it’s actually 12.73 Vdc.

This is handy. Is a nice complement to aprs.fi.
