Hi all, I used to be smarter but now not so much...I have a Galaxy Saturn and trying to wire it to a Turner M+2/U hand microphone I have, the Turner has 4 wires ( Whiet, Black, Red, Shield). I have tried various combinations but I am missing something. The mic works and I can get it to key up but can not figure out proper wiring to get audio. Any help GREATLY appreciated! Thanks, Adam

Hi, yes, I had that info but as mentioned I am not too bright. Hoping someone has a Galaxy Saturn and can help. Thanks for answering!

Anyone else? Adam

It doesn’t have to be a Saturn...that radio should be the same as any 4 pin Cobra wiring:

1 Shield
2 Audio
3 TX
4 RX

Which I believe with that mic would be

1 Shield
2 White
3 Black
4 Red

Can anyone confirm?
 
Hi, the Saturn must be different, that won't even key the radio but thanks for trying..

Well, that’s no good.

Have you used the mic before or happen to know what it was last connected to?

I’m thinking that if it was running an old relay switched radio, it may need some internal reconfiguring.

Hi, I am thinking there is something wrong with the mic so for now I will leave it till I am back in the mood. Thanks to all! Adam

I do that all the time ;)

Might be good, when you’re up for it, to post a picture of the switch’s wiring inside the mic. Just an idea.

Good luck!
 
20191219_211436.jpg If this gets too complicated and youre looking for a mic that sounds as nice as a Turner might I suggest the Realistic 21-1173 amplified desk mic. Works great on my 2995dx. All reports are very loud but very clear also.

If your mike was set up for relay switching, this might explain the difficulty.

Modern radios expect the mike switch to close pin 3 to ground for transmit. The diagram in the manual linked above shows that the mike switch only connects the red wire to the black wire when you key the mike. No connection to ground from either of those two wires.

If the red wire is connected to pin 3, now hook the black wire to pin 1, alongside the shield braid.

And if the black wire is on pin 3, ground the red wire.

Pin 4 on the mike plug is not used for the Saturn.

Well, Nomad - you've done spilled the beans...

Suprized no one posted this...it always seemed to come up at least once a month on CBTicks...

Per Nomads' advice - locate the Shield wire - you will need it for Pin 1-4 on the SATURN Mic socket is shorted together...so if you wanted to keep "open - floating" wires - from getting bored, give them something to do, make sure you send them to either Pin 3, or Pin 4 - as a catch all when you need TX mode in Pin 3 - and - Pin 4 is RX (thru shield on Pin 1) and your leftover is Audio (White) for Pin 2. Note it, that Audio White, is switched on a separate pole.- along with Battery + on it's own pole of the switch assembly...

So if you wish, you can send Pin 2 direct - meaning the wire terminated with 33K resistor - can be wired direct if you have shielding issues and a noisy receiver if you plug the mic in and find out the open Audio line is now making a 60/120Hz buzz - White Audio Wire being left open can do this - just place it on the 33K resistor out (by cap) to terminate it direct. I've encountered this before on people with the tendency to remove limiters and therefore they remove the RX mute feature it provides as a secondary afterthought for some.
