On those ICE preamps, check the small dipped inductors, because they can blow open if the preamp is exposed to a high enough RF field. If your preamp is on a rx antenna and you are transmitting with ham QRO nearby that's enough to do it. IIRC powering down the preamp isn't enough. It has to be behind some kind of feedline relay that opens. 73 Rob K5UJ _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector |
