Raspberry Pi 3 with Direwolf I-Gating to a local installed copy of
APRSC talking over the Internet over GSM or 4G LTE mobile Wifi
hotspot. Using APRSDroid to talk to Direwolf over Wifi. Have it
working now. Works great. And, if you connect a radio via
Tigertronics Signalink USB soundcard to the Pi 3 it allows you to
I-Gate for other RF APRS sources. Personally used it in this manner
and it works great.
But, make sure you filter heavily so that you don't inadvertently
I-Gate for anyone else while you are moving . . . APRS police get
their nickers in a twist over that kind of thing.
