Alan,
The 4 pin vs. 8 pin is not your only problem. For pin to pin
connections, I suggest you consult G4WFW microphone connection database,
it is quite helpful.
The D-104 microphone element is quite high impedance, and some have
suggested simply using a series resistor to mitigate the high vs. low
resistance microphone impedance situation, I would suggest that a simple
FET stage could solve the problem. The D-104 mic feeds the gate of the
FET and the output is taken from the source (or drain). There was a web
reference to the Heil FET amplifier that was recommended, but I have
lost it. I have it on my hardrive and will send it to Alan in a
separate email. -- the reflector will not accept html nor any other
resential

Colleagues:
Am looking for assistance in rewiring an Astatic D-104 Astatic microphone
(T-UG9 stand) for use with my K3 and K2 transceivers. The mic is presently
wired for 4-pin Ten-Tec.
Any assistance would be greatly, and gratefully, appreciated.
