anyone have a wiring diagram for a astatic d104 to a heathkit dx-60?
thanks jack

No, but you can do this.

1. The wire with the shield around it will be the Audio hot lead. Hook it
to the pin that hooks up to the speech amp input.
A. You find that by eyeball or finger poke.

B. Eyeball is safer. It will have a 100K or so resistor in series
to the grid of the 1st tube used for the speech amp. Probabably somethink
like a 12ax7.

C. Or turn the mess on. Listen in another receiver and get it to
make a signal while in the AM mode of course. Then put your finger on the
pins of the female mike connector to determine which one hums. Thats the
audio input line. Course you may get a shock if you touch the PTT line.
But it won't be that bad.

Then the other connection will be the PTT line. Confirm that by putting a
clip lead on it to ground. It should key the TX.

On the D-104 mike there are lots of possibilities. Just take a ohm meter
and find the one going to ground when you close the slide on the mic. Bear
in mind you will probably have to connect the shield of the audio line to
system ground which will then key the rig.
