[Elecraft] RF in Microphone

[Jim Kutsch]

I am a new K3S owner and very pleased. However, on SSB, I am getting reports
that my audio is distorted sounding like RF is getting into the microphone.
I'm using a Heil PR-781 with the XLR3 to 8-pin microphone adapter cable. I
had some RF microphone issues earlier using the PR-781 with a KX3 but a
better shielded mic cable and a common mode choke resolved it. Any
suggestions before I go in search of a different mic? Also, any
recommendations for a boom mount microphone that would be a better choice
for the K3S than this PR-781?

 

Thanks and 73, Jim, KY2D
