I connected a Cobra CA-75 power mic to My Cobra 25 WX LTD Classic and it
squeals like crazy. If I hold it just right it won't but it's too prone to
squealing. The radio is fine with a stock mic and the power mic is fine on
other radios. I have also had another radio with a power mic in the same
vehicle with the same antenna with no problems. Is there an easy solution to
this?
