Is anyone out there using a K-3, Microham Uflymic combo? I've got terrible feedback/motorboating whatever you want to call it. I've never used used a "bias" mic but this seems too sensitive. I have it hooked to the rear of the radio low amp. Everything in the Microham is turned off preamp-wise Mike/aj9c You can respond direct to: aj9c at indy.rr.com
