D104 I have a D104 mic with a amplifier and I want to use it with the ICOM 706 tranceiver. What must I do to wire it to the Icom mic plug. Also, what would the amplifier do in this case? Thanks for your help. Sonny Campbell

There were different wiring schematics for the various models of D-104 mics. Amplified D-104's, if you have a TUG8 stand then you only have four wires, a shield, a transmit audio (white), and two PTT wires (red+ and black-). If you have a TUG9 or TUP9 stand (like the ones that are usually on a Silver Eagle or a Golden Eagle) then you have 6 wires to contend with. You should be able to find the wiring diagram needed to wire your D-104 to the IC-706, (mk2?). I would recommend that you also do a modification to the D-104 to make it more compatible with modern radios and their much lower impedance requirement. Kits are available online to do this. Your 706 needs appx. 600 ohms. Using a older D-104 will make your transmit audio sound bad. Also, keep the potentiometer in the base of the mic at the lowest setting possible. Adjust only until you are heard with a normal volume. Cranking it up won't get you out any further and will only distort your transmit audio.
