I need ideas to cure desense on a 10 meter repeater. Details; 1. 100KHz split, (29.66 out 29.56 in) 2. Maxtracs on both ends, UHF link 3. Several miles of separation 4. Sometimes it works OK with no desense, but usually when the tx comes up, a buzzing type of noise wipes out most signals, even ones that were full quieting before. 5. The buzzing sounds like powerline noise. 6. There is some kind of wireless node nearby.
What other types of noise generators could be exagerated by the additon of the 10m transmitter? Is it possible to make a notch filter out of big hardline at 100KHz with acceptable insertion loss? Would a window filter (DCI type) help with that type of noise? ...Keith WE6R
