Hello Mick,
I was having the problem with RF getting into microphone. Currently using microphone MH31 with installed BX-184 kit into it with Heil HC-5 microphone element.?So the issue with the RF making distortions in microphone was really annoying. But I could fix this issue. Just solder 220-270pF?caps from microphone terminals to the ground and unwanted RF will be filtered to ground allowing AF to pass to the radio. For now I do not have any unwanted RF in my microphone. You can modify in this way all AF or switching lines in microphone cord to remove all possible RF in the wires.?
But the issue I am having is like delayed and step by step coming back receive sensitivity. It is more looks like the AGC restoring RF gain? to initial after a strong signal on the input, but takes longer. And this happen only on 20m band.?
