Question about Cobra Radio Communications

1 Answer

I have a 1990 cobra 148 GTL with 5 pin side-mounted mic. I recently bought a Barjan 5 pin noise canceling mic. Is the mic compatible with my cb, or do I need to change the wiring? Larry

The wiring is not likely to be the same.

The information on the radio is here:
http://www.cbtricks.com/radios/cobra/148gtl/index.htm

You will likely need to open up the mic to identify what your wires connect to to determine the correct oreintation. it is possible too you may find one of the models listed was used by Barjan and is nothing more than a rebranded microphone.

Cobra 148 gtl-st wont transmit but receives great


Check first your microphone

• check if TX is engaging when PTT is pushed.


• check for continuity ( mic and cable )



If you have not done these steps,

try it first, or borrow other compatible mic for Cobra 148GTL

from your friends on air.

148 gtl 5pin


Looking from inside the radio at the mic jack, with the nub down. Starting from the left is pin 1, pin 2, pin 3, pin 4, and pin 5.

here is the colors that should be attached to each.

1 is white.
2 is sheild.
3 is black.
4 is red.
5 is blue.

Hope this helps. Take care in soldering. It is easier to reach the pins if you remove the 4 screws that hold the face plate on. Be careful not to pull another wire from somewhere.
