Is there any carrier detection in pskmail/fldigi ?. When i did try to communicate with a IS0GRB-3 I notice that my set did start transmitting during a frame that he received of IS0GRB-3 I had already a connection with IS0GRB-3 and did try to get a server list. Data was being received, but not finished yet and already pskmail/fldigi did start transmitting. My communication with IS0GRB-3 is a bit hard because i do only have a QRP station with 1 watt and a suboptimal antenna. 73 PE1PRX Johan.
