[Elecraft] RFI

[robby robertson]

I thought my microKEYER was guilty of RFI but it turned out that the audio
patch cables for line in and line out had a less than 10% shield. I
temporarily solved the problem with ferrite but a more permenant solution
will be RG-58au.

Then I lost microphone audio and just got a buzz.  I removed the RJ-45
connector from the back of the MK and plugged it back in. Problem gone. Self
cleaning contacts are great but you have to activate them.
