Yes, it's quite easy to run a SDR receiver for APRS for VHF 1200 bd or
9600 bd or HF use with 300 bd AX.25 or APRS over digimodes with APRS
You can move the received audio over a virtual soundcard to Dire Wolf or
UZ7HO sound modem with Virtual Audio Cable or VB-Audio virtual cable.
One thing to consider is the latency through the SDR program and the
virtual soundcard. It another station with a conventional receiver
receives the same APRS packet it might igate it before your SDR station.
If you like comparing station stats on APRS.FI or similar then it may
give a misleading indication of performance.
