[Elecraft] MD2 resistor mod - a different approach?

[W3FPR - Don Wilhelm]

Jean-Francois,

Fortunately the Kenwood mic has similar configuration header wiring compared 
to the Elecraft, differing only in having 5 volts on pin 5 rather than on 
pin 6.  If the Kenwood mic is only used with the K2, you can re-wire the mic 
plug to grab the 5 volts on pin 5 instead of pin 6.  OTOH, if you must 
retain the Kenwood wiring, proceed as indicated below.

If the Kenwood mic is one of those listed in the Elecraft KSB2 manual, you 
would still add the resistor between pins 5 and 6 at the back of the K2 mic 
jack and be certain nothing is connected at the mic header to pin 6.  To be 
safe, disassemble the Kenwood mic plug and be certain nothing is connected 
to pin 6 inside there too - if there is a connection, it should only be used 
as a tie-point and can be removed (if there are two wires on pin 6, remove 
them from the pin and connect them together) - I think I have covered all 
possibilities with that <G>

Then on the mic plug for the MD2, connect pin 6 to pin 1 - the 5 volts 
(direct = no resistor) remains on pin 5 to satisfy the Kenwood mic, and will 
have the resistor in series at pin 6 for the Elecraft mic requirements.

What are you suggest if I must switch often between an MD2 and a
Kenwood hand mic.... It is a little bit hard to remove and add the
jumper each time... Maybe if we can have those jumpers more
accessible.... from dip switches somewhere...
