Let's turn your Yaesu mobile rig (FTM400, 100, 300, 500) into an APRS igate! Everything you need is already in your box, plug your radio (SCU-20 USB cable) into your PC or Raspberry Pi and install Ygate.

On your Yaesu:
APRS - APRS Modem: ON
Config - DATA - Com port settings - Output: PACKET
Config - DATA - Com port settings - WP Format: NMEA 9

Special thanks: John Belstner. Thanks for adding the socket-reconnect code, ygate is much more robust now.
