Yaesu’s FTM-350R mobile APRS radio has very sparse documentation on how to communicate with the radio. It’s possible to listen to the data output in 3 different formats: Packet, waypoints, or GPS output. Here are some captures of the various output formats, using a radio with the version 1.2 firmware update applied.

All of these files were capture from a Yaesu FTM-350R with firmware version 1.2. For all captures, the comm settings between radio and computer were 4800-N-8-1, XON/XOFF handshaking.

 

The “packet 9600” file was capture from the Puget Sound area’s two 9600 baud APRS channels on 144.350 and 440.800. “packet 1200” was captured on the 1200 baud frequency of 144.390.

 

The different modes were selected using the E16 menu, option 2: “GPS OUT’, “PACKET”, or “WAYPOINT”. The “startup” file was capture with “PACKET” chosen.

 

Here’s a brief excerpt of the Packet format. The full sample files are attached.
