I am a new Var- AC user. I have had several strange experiences starting out. ?The initial usage was smooth enough. Then the comm port was seized by another process and the application could not communicate with the radio. I computer programmer friend of mine, who is also a ham suggested that I renumber the port to another number. That didn't work. My Elmer went in and set everything back to the original number. Thing started working again spontaneously without diagnosing or fixing the original comm port problem. So here is my immediate concern. The radio is transmitting e.g. beaconing and attempting to initiate a QSO. The problem is that the software isn't making it's usual noise when the radio is transmitting. Problem 2 is that when the radio transmits, it emits no sound when you listen to it with the monitor function. I have verified that it is on and that the volume is way up. Pskreporter verified that I actually transmitted. So ?what is going on? I have only done one QSO.?
