How do i convert my cobra 29 nw mic to a road king 56 mic?


Look closely at the jack for the microphone and you can see the small numbers that are on it. On the Roadking red and shield (bare) go to 1. White 2, Blue 3, black 4 and the yellow in the cable does not connect to anything.

I have a Cobra 148 mounted on the hump in a pickup truck and it works fine. Then I plugged in a old Turner +3 desk microphone and I get bad feedback when it is keyed up and I can also hear my voice thru...


You're most likely getting lots of RF feedback from the metal cab of your truck,combined with the real sensitive nature of the amplified Turner mike.I would put an old original Cobra (coffin mike) handheld mike or a Astatic Roadking 56 (RK56) on it.They are really hard to beat,especially when you have lots of feedback & squealing. I also have a 148GTL (malaysia made) that has a Turner +3 deskmike & it squeals in my truck but not in the house. The 148GTL has given me better service than ANY other radio I've owned.It has 120 channels (freeband) & upper & lower sideband. I think mine is a 5pin Cobra-type plug-in. Try a simpler mike & good luck. Squirrly

Microphone


Hi,

If the radio receives OK and the TX red LED will not lit up when keying the mic, then it is a mic or mic cord or mic connector problem (or pin configuration). Internally to the mic, there is a switch for keying the PTT. This should be check down to the coiled cord to the connector.

If all of the above checks OK, then you would need to check the TX/RX regulator/switching circuitry.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
