http://aprs.fi/?c=raw&call=G4PID-14 says it's a 0xc0 byte (does not have
an equivalent printable character):

I wonder if W5YD-5, an xastir instance, could have replayed it back to the
APRS-IS somehow? The path does not make any sense. Or is W1GG-1, an aprx
igate, bugging somehow and transmitting it to RF, it's comment says it's
a TX igate? http://aprs.fi/info/W1GG-1
