I'm trying to wire an Astatic D104-M6B for a Swan 270B transceiver. Can you provide any help?

Here is the wiring diagram for connecting a D104-M6B microphone to a Uniden 880 radio:

• Shield: Connect to pin 1 of the microphone jack on the radio
• White: Connect to pin 2 of the microphone jack on the radio
• Red: Connect to pin 3 of the microphone jack on the radio
• Black: Connect to pin 4 of the microphone jack on the radio

It's important to note that not all Uniden 880 radios are wired the same way. If you're unsure about the wiring on your specific radio, it's best to consult the manual or contact Uniden customer support for assistance.

Is the d104 a amplified tug8 (4 wire) or tug9 (6 wire)
or is it a non amplified mic?
Found this...hope it helps..........
Astatic (4 wire)
1- White
2- Shield
3- Black
4- Red

Astatic (6 wire)
1- White
2- Shield
3- Blue
4- Red
Black- N/C
Yellow- N/C

You've probably already found the answer to this question but doing a search for D104 wiring to ICOM will show you what you need. If the connector is the 8 pin circular one, then the PTT and MIC connections are the same for all ICOM radios.

Hope this helped,all Astatic mics are wired the same.

This works for any mic.
dont worry about color codes. look at the switches.. there will be a common on both poles of the d104.. those need to be tied together to grnd. pin 1 on mic . the others d104 on n/c side is your rx. pin 4... the n/o one will be your tx pin 3 the other n/o will be audio and will have a wire from the mic element also on that pole of the switch. pin 2..

Hi,

This must be the right pinning

Pin 1 = shield / blue
Pin 2 = white
Pin 3 = red
Pin 4 = black

good luck,
Gerard

1-White
2-Shield/Blue
