I am trying to use AirMail to connect to RRI-DTN stations to handle NTS messages. I have confirmed that AirMail is properly configured and it successfully initialized the PK-232MBX TNC that was tested and provided by RRI. ‘The receiving station confirmed that my signal was heard and that it was responding. However, my TNC times out after 30 seconds and does not connect. ‘It is curious that the monitor window shows activity with the radio on, so the TNC is getting input audio. However, the activity goes away when AirMail is launched and the PK-232 is initialized. What am I missing?
