Newbie question here. I have been doing some research on HF APRS on 30 meters. This look very interesting to me. Especially in combination with PSK63. For example, the work by WA8LMF ( http://wa8lmf.net/APRS_PSK63/index.htm). Is there a way to set xastir to do something similar? I really would like to use opensource software for this?
