Dittel Dynamic Mic wiring

Hello all, I have a dittel FSG-60M Radio in my glider. It has a mic plug

Dynamic Mic from Wings and wheels. The glider was hard wired with a
PTT and a separate speaker. I have removed the plug on the end of the
mic and I wish to hard wire the mic. A brown,white wire with a ground
are in the mic line. I do not have a wiring diagram for the mic. I looked
at the FSG-60M installation instructions was trying to figure out if an
amplifier is needed to run the new set up. W&W was not very helpful
and I could use some expertise as I thought it would be rather simple
to replace the mic. The radio is set up for a dynamic mic already. It is
inscribed on the outer case. I do not believe it was ever changed from
the previous owner. Anybody with experience with this set up? Thanks,

Doug, no problem.
From what I read, I didn't see which mic you're going to, thus no further info.
Pass that on (what mic you're going to), maybe one of can provide some more info.
If nothing else, this thread may come up (with similar questions/search), thus more info linked for the next person..... ;-)

Hi Charlie,sorry it is a Dittel F10039 Dynamic mic. It has a ground
braided wire, one white wire and one brown wire.

Hi Doug,

I am not familiar with the FSG60, but on some other radios, different pins on the harness plug are used for dynamic mics than are used for standard (or electret mics). Since you have the manual, you should check the wiring diagram to see if this is the case for the 60. If it is, that explain why it did not work when you connected it to the old jack wires. If the manual does not make this distinction, then some of the older radios have a potentiometer that you adjust with a screw driver for the gain required of a standard vs dynamic mic.

In terms of the mic itself, there should be two wires plus a ground wire. The ground is usually a shield or a bare wire. As far as the other two wires, it does not matter how they are connected as far as + -. Just like a speaker, it does not matter which direction the current flows through the mic. So, as long as you can determine the ground wire you are set.

The FSG 60/ FSG 60M can be set for an amplified microphone or a dynamic
one. To select, the shorting plugs at P 3009 and P 3011 are reversed as
shown in Fig. 3-11.
See

P 3009 & P3011 ( Jump Connectors ) are accessable after opening the upper
cover.
