[Elecraft] K3 - Diary of a mad microphone

[Dave Martin]

Yeah, Joe, I didn't think my voice deserved a two hundred dollar
microphone.  I'm using a Motorola hand mic from the land mobile world
because I had it in stock.  It has an electret element with a
transistor amplifier circuit.  I simply cut off the Motorola connector
and put on one for the K3.  I also strapped the PTT switch contacts
that switch the mic circuit to avoid the possibility of a big bump
when keying up.  Does it have flat response out to 20 kc?  Doubt it.
Good strong lows so I'll sound beautiful?  Not on a communications
mic.  Does it have a nice rising response to give the right brilliance
for pile ups, or for casual use?  Don't know.  But it sounds fine with
the K3's equalizer set flat straight across.  I'd say keep it simple.
Works for a simple guy like me.
