Astatic D104 to Lafayette SSB140

[BigLion]

I have wiring diagrams that state a blue wire, but I only have shield, white, black, red. Anyone ever wire one of these to a Layayette SSB140? The plug is a DIN 5 pin. Thanks.

This topic has some information needed, basically the same but the pinout, [Please login or register to view this link] ,

Telesat SSB140
1 - white (audio)
2 - red (TX)
3 - blue (switching ground)
4 - shield (mic ground)
5 - black (TX)
Using a 4 wire mic, you need to jump pins 3 and 4.

Like I said in the other topic the radio might squeal during transmit because of sharing the mic ground.

OK I see a problem, the TUG8 is for older tube-type 4-pin CBs, the TUG9 is required(has the blue wire). Guess I'll ebay the tug8 and find a tug9.

If the D104 has a 4 pin plug on it now hopefully wired for Cobra then a cheaper approach would be to get an adapter from one of the sponsors or off the internet.

Excuse me... Just wired one not too long ago.

1-Audio
2-TX
3-GND
4-GND
5-RX

It is a din-type plug??

[BigLion]

Yes, a 5-pin DIN. I wired it as stated, and a loud SQUEEL hits me when I power on the rig! I thing the audio feeds thru the mic, and linking the two grounds causes mad feedback. I bought a TUG9 on ePay and will try that. The TUG8 is in mint condition, so will post for sale here.

[MDYoungblood]

Yes the TUG9 mic will be better, the switch in it lets the TX/RX break before making the mic contacts eliminating the squeal.
