wires different color than what should be

[crowhorse55]

Hi guys .. I am trying to wire a mic to my Cobra 148 GTL – 4 pin

I have a older.. cobra dymamic mic…the wire colors on the mic are

White / audio- no.2 /, red /TX no.3 / black/RX and screen,common/no1

Also have a Uniden mic 4 pin.. with different color wires

Red is on 3,yellow on 2 ,black,on 4 and shield /ground on 1..

I guess my question is what wires go where?

Thanks for any help

well I hate to tell you but you are going to find a lot of different color wires inside a mic cord. just about ever vendor will use a different color combo and if the cord was changed by a shop it could have wires hooked up in different positions. so do not get locked in to color coded wires. just check how they are hooked up for each purpose and use it where it goes.
if both mics are wired for a cobra radio it will work unless it is a din plug. as long as it is 4 pin or 5 pin to match up.

You could go to CB Tricks and get the pin out for the Uniden microphone by looking up the radio it came from and change the wiring to match the Cobra. Looks like you already have the ground/shield on the right pin. Did you try the mic before rewiring it, most Cobra and Uniden wiring is the same.

Well , i used the ohm meter as described below... the cobra 148 GTL works on the RX...I can hear all over Texas, Florida on AM & SSB however I do not believe that I am getting out.. I have asked for a basic radio check, for 2 days now...nothing.. I read where if I put on PA with an external speaker and talk into the mic , I should be able to hear my self.. Well I don't... anyone one have any ideas?? should I open it up and test or adjust anything..?

Basic Mics - These consist normally of three colored wires and a braid/screen. The braid is the common wire for the TX/RX/Mod and is normally twisted around the modulation wire. If you get this in the wrong place you will be fighting an uphill battle. 4 pin mic sockets are about the easiest to sort out, the 5 pin din can be very hard to wire as there's not much distance between the pins and can "short out" easily. Normally when I'm wiring 5 pins I put a sleeve on each wire to prevent this.
Back to 4 pin. Put the plug into the radio and look at the solder pins. Two of these pins will make the radio receive (sound) so find out which two these are by shorting a piece of wire across the pins with the radio on until you find the two that make sound. One of these pins will also be common to making the radio TX so that pin will be where the braid is soldered to. Once that is soldered on its pin touch each colored wire on the other pin until the sound returns. Solder that colored wire on the other pin. Next you need to find the TX pin. With the mike key depressed touch the other two wires briefly on the TX pin until you find the one that makes it TX. Solder that wire to the TX pin. Finally the modulation wire will go on the remaining pin. Often the modulation wire is the yellow one or it has the braid wrapped round it.
