Products for amateur radio including APRS applications
- 2m Transmitter MX146 from SRB
- OpenTracker+
- Tracker2
"The OpenTracker+ is a simple, low‐cost amateur radio data encoder capable of generating 1200 or 300 baud AX.25 packets using the APRS™ protocol, as well as PSK31 text beacons. It can be connected to a GPS receiver to report position, course and speed, time, and altitude, or it can encode and transmit data from a supported weather station. It will also report telemetry from its onboard temperature and voltage sensors, and an external counter input can report a cumulative total of counter events or the number of events since last transmission.. With its expandability and ease of reprogramming, the device can be adapted to a wide variety of tasks."
I think both APRS products are designed to connect to a Kantronics TNC
