[Elecraft] RF in Microphone

[Michael Walker]

Also,

Have a read on the YCCC's notes on chokes.

http://www.yccc.org/Articles/W1HIS/CommonModeChokesW1HIS2006Apr06.pdf

Not only will it help with RF issues on transmit, it will help all all the
noise in your shack and allow you to hear better.

I bought a case of Mix 43 chokes, and I've used them all.  Worth every
penny.
