[Elecraft] K3S Microphones

[Russ Tobolic]

I have K3 S/N 732 and use a $2 electret computer mic I bought at a yard sale.  They had a white one that was only a $1 but I chose to go the more expensive route and buy the $2 black one to match the K3.  My settings are -16db  up to 400 Hz, 0dB at 800-1600 Hz, and +16 dB at 2400 up and I get good audio reports.  After 8 years I did recently splurge and upgraded to the Koss SB-45 which works great.

I use a Heil PR 781 with great success.  The K3S TX EQ is set as follows;
  -16 dB @ 50 Hz, -12 dB @ 100 Hz, -6 dB @ 200 Hz,  and 2400 Hz @ +3 Db, 
3200 Hz @ +6 dB.

Working distance to the face of the mike is 4" to 5" on axis {one fist}  
so as not to enhance bottom end due to proximity effect, typical of 
dynamic mikes.    The MIC SEL is set for FP.H with the mike gain at 40 
and the COMP at 15.    The PR 781 is mounted on a small spring loaded 
desk boom that allows for easy placement for operation and moves easily 
out of the way when not needed.  I did make my own mike cable using some 
Belden 8771 which is 3 conductor shielded cable connecting between the 
XLR connector and the Foster connector.  The cable shield connects at 
the radio end only.
