I have to manually add a site on the new CT csern system because I don't have internet service for my pc at this time. So I add the control channel which is 773.93125. Upload it to the scanner and get full signal as indicated by the steady T icon. It's stopping on active TG's but no audio. The voice channel is flashing on and off and is coming up as a few different odd frequencies which make no sence. 796.996875- 795.96875 and 849.4125. Does anyone know what the deal is?
