I have used the USB serial cable for radio programming with the FTM-400 and FTM-500 to provide APRS data to YAAC for several years. ?My setup is for monitoring APRS and Winlink email as well. ?This is why I have a digirig attached to the radio. ?I did not want to switch cables to go from Winlink to APRS. ?
