Is there anyone out there in the Elecraft ether that
is using or has used an ElectroVoice Model 638 mic
with the K2?  If so, how did you interface it's hi-Z
to the low Z of the K2?  What about audio reports,
etc?  I used to use one of these with my old Heathkit
SB-101 and it was a great microphone.  Anyone out there?

Mark, the emitter follower amplifier for the D104 should work for any Hiz
microphone as far as impedance conversion is concerned. I looked up the 638
on the internet and I remember this one. It is a beaut! Looks like there is
some room in the base for the amp. Change the 3 wire cord out for 4 wire and
power the amp off the K2 5v available at the K2 mic connector.

Have fun, Jim W4ATK
