I just put up an 1/2 wave antenna for 160 meters that is 260 feet long and center fed with 450 ladder line. When RXing on all bands and moving the PWR contorl to 11 watts or more so the relay in the PA switches over to high, I get erratic noise in the receiver. If I back the PWR down to QRP, then RX is OK again. I am almost sure that this noise is rectified AM signals within the TR switch. Not sure if this can be expected with this switching method or if I have a component that's bad. Most of my antennas are Loops or match and fed with coax, and don't display this condition. Several years ago I had a Ten Tec transceiver the experinced the sam problem, I resolved by building a high pass fillter and installing it in the receive line and the problem went away. Not sure there is room for this in the K2. Any ideas?
