Ian Wrote: I am at times having desense (ie scratch ) especially in windy weather occuring on repeaters B and D. It doesn't seem to affect the desense wether the transmitters are txing or not. There isnt any problem of the repeaters affecting each other, they all work great just the problem of scratch coming and going .A, C and E do get scratch on occasion but no where as bad as D and B. D and B works great sometimes (clear with no scratch)and then reception will slowly develope major scratch and then slowly clear up -possibly electrostatic or wind moving the antennas?
Maybe try these?
Sounds like you have corona or charged dust particles.
