Strange event with CM7777 system
About one year old CM7777 amplfier set up suddenly went blank for a few seconds then came back. A few days later no signal detected for several hours. Next day normal operation. Yesterday cut out after a few minutes. Power inserter and power supply connections seem okay.Tinkering with connections on mast. Everything seems okay, connections are all tight, baluns all attached, etc. Accidentally bumped a cable connector against the mast and got full signal. Have connector clamped to mast with vise grips. Totally baffled by this..
