[Elecraft] K3: Heil PR20 Microphone

[Rick Prather]

Howard,

I am using a PR20 and am able to run my mic gain at about 20.  

I use it on the FP set on H and the onboard preamp turned on  ( press 7 )

BTW, I have tried several mics and use the Yamaha CM500 for DX'ing but for rag chewing the PR20 consistently generates the best reports.
