My friend, K3 user is getting ready for CQWW SSB. In his installation the rotator control box that has pretty large transformer inside. The box is only few inches away from one of the two K3s and cannot be moved. He has discovered that magnetic field created by this transformer interacts with the AF transformer (Line in) in K3. The indused 50Hz noise is only 20db down from the audio signal. The noise is gone when line in is switched off in the menu but that leaves him without voice keyer which is tough to be deprived of in 48 hours SSB contest. Has anybody found a solution yet. He now thinks of taking the transformers out of the radio an bypassing them. He thinks that the problem roots to the fact that the K3 cabinet is made of aluminum.
