How do I wire a 4 pin mic to a Uniden ship-to-shore radio?

you have to check to see that the pins match the pins on the radio. Get a schematic of the radio and look at the mic area. Usually it will tell you how to hook what wire to what or you may just get lucky.

I need an FS-1503 mic wiring schematic. It is an 8-pin and I want to convert it to 4-pin. Any tip please?

find the grounds

on 8 pins you have two grounds black wire and copper screens

connect both to a flying wire

you can use a beep test digital meter {2$ type} to find the TX line

white or yellow is usualy audio to the radio from the mic

and thats it
oh yey too find the ground on the radio look up its details

you can use the beep test also to its neg wire {not the case it floats not + or -}

the case is for the screen wires coppers
the black wire is ground on the mic plug only
the white or yellow will be audio to the radio
the orange or blue will be TX enable and gets shorted to the ground black when you press the TX key

so armed with this
good luck and happy festive season....!!!

I need to wire a silver salute mic to a cobra 142 gtl 5 pin what color wire goes towhat mic pin

dont go by colors.. go by what wires are on the switch and mic element.. mics can be rewired and no one told you the colors could have changed FYI..

Pin #1 ~ Audio
Pin #2 ~ Shield
Pin #3 ~ Receive
Pin #4 ~ Switch Wire
Pin #5 ~ Transmit

always go by connections not color of the wire. that way you learn and you can do any mic. to any radio.

I have a radio shack trr470 and I bought a cobra CA-76 power mic with a 5 pin conector instead of a 6 pin conecter by mistake .can I use this mic on this radoo .do you know what cooe wires form tje mic go...

according to the schematic I just looked at the mic for this radio is a 5 pin. As long as it is a plug in and not a din you should have no problem connecting it.All you have to do is re-wire it and be on your way.

I have a 5-pin cobra power mic model ca-76 and i need to make it a 4-pin power mic

most 5 pin with wires can and will work for a 4 pin--you just need to know the pin out versus the wires in the mic you are trying to wire it to.

Does the roger beep come with instructions? It can vary between beep boards.

Typically it gets installed inline with the mic jack.

There is a wire or pin on the board where the tx wire, and the rx wires go.These wires get disconnected from the mic jack, then a wire goes to the tx pin. Then there is an audio wire that gets connected to the audio wire of the mic jack. Then the black wire to ground, and the red wire to switched 12v right off the power switch.

Here is a schematic of the board connected to the mic jack so you know what pin is what.

Again, I would need to know what roger beep board you would like to install.
