I have taken the amplifier out of line and had the same results. I've also taken the duplexer out completely, and run the RX on the top antenna, and TX on the bottom. I thought for a while that this solved the problem, but it ended coming back eventually. There was quite a bit of desense in this configuration obviously, so the feedback probably just wasn't strong enough to overcome it, for a while. I don't have a circulator in line. 73 Jeff N1ZZN
