After several months of trying to figure out how to use a Baofeng as a TNC for things like APRS tracking, I finally found a method that works.
I tested SARTrack's software for APRS station tracking and APRS messaging.
I did a field test of PinPoint APRS tracking software.
My first ham radio was an 8-watt handheld Baofeng BF-F8HP. Combined with a Nagoya NA-771 15.6″ whip antenna (pretty much the standard for HTs) and a Btech QHM22 speaker mic, I found I was easily able to get an audible signal with some slight noise hitting repeaters 20+ miles away and people didn’t have any trouble hearing me.
Since I’m driving a leased vehicle, I didn’t want to drill holes into the car to mount my ham radio microphone. I was very happy to find an adapter kit that slips over the round part of the microphone mount, creating a sturdy ferrous metal surface to attach to any magnetic mount.
