Their website says they use 144.340 MHz for APRS and ask a few local
igate operators to change frequencies to support the flight and
recovery. I got the impression they put a portable digipeater in the
expected recovery area, but I may have read that wrong.

While they're probably not bothering anyone on 144.340, I still don't
agree with beaconing full NMEA sentences. Base91 compressed packets
seem like a better alternative for high-accuracy beacons.
