[Elecraft] K2 with Digi Keyer

[Don Wilhelm]

Gary,

You can use the Heil Proset by either changing the K2 microphone 
configuration header to match your microphone pinout, or you can use the 
Elecraft pinout for the mic configuration header (all jumpered straight 
across) and use the Kenwood adapter with your microphone.

The biggest difference between the Heil Proset with the HC5 element is 
the output level.  The Proset-K2 uses an electret element for greater 
output level.  The HC5 element is a dynamic type and has a lower than 
normal output level.  You may need a mic preamp to use the HC5 with the 
K2, particularly on the higher bands where the transmit gain is lower.  
With the KPA100 installed, it usually is not a problem.

See the KSB2 manual for information on wiring the K2 microphone 
configuration header.
