Sorry all hardline heliax .I did have lmr400 in the first months on my VHF/uhf repeaters and then replaced all cables after the desense was a major problem and we havent had a problem since .I feel it could be the regulators on site ,some sugestion was to put a clip over ferit but I had a BP regulator and it had pathetic interfence coming out of it and I installed 1uf caps on all pins and it cleaned it up great so I may try it with the regulators I am currently using .moringstar 20 amp regs
Thank You,
Ian Wells,
Kerinvale Comaudio,

Could this be LMR cable noise? What kind of coax are you using?
