[Elecraft] K2 microphone options

[Don Wilhelm]

Greg,

The K2 needs a high output microphone, and that usually means an 
electret type element.  Most Icom mics (and Heil mics with the 'iC' 
suffix) are the high output electret type.  If you choose one of these 
and wire your K2 configuration header for ICOM (with a 5.6k resistor 
between the AF pin and the 5 volt pin), you should be able to just plug 
it in.

The other electret mic that I know works well are those from TenTec - 
the 701 is the hand mic.  They come with a 4 pin mic connector that you 
must change to 8 pins, but you can wire the new mic plug for any mic 
configuration that you want - I suggest the Elecraft wiring - straight 
across (use computer jumpers) on the mic header.

73,
Don W3FPR
