HERE IT IS THE CORRECT MIC WIRING FOR THE REALISTIC TRC 447.

1.)Audio
2.)RX
3.)TX
4.)CH.Down / Shorted to Ground
5.)Ground
6.)Ch.Up / Shorted to Pin 4

Be extremely careful when wiring this radio! pin 4 and pin 6 carry voltage shorting these to the wrong place can result in serious damage to your radio.

    yes, come off the transmitter with a jumper to the freq counter input, then come out of the output side of the freq counter to the input side of the amplifier

Is it possible to put in line a frequency counter and a linear at the same time for cb

  • Scott Rosendaul Dec 11, 2014

    yes, come off the transmitter with a jumper to the input side of the freq counter then come off the output side of the freq counter to the input side of the amp, from the output side of the amp you should use a swr-power meter to set up the output of the amp

Six wire mic to a trc 495

Realistic radio mics are all , except for a few , wired the same. All you have to do is look up the wiring for the realistic 5 pin din plug . One of those wires in the mic is not going to be used the thing is which one . Connect the wires as they are mentioned in the diagram then if it doesn't work connect the last wire.

I need to know what colers go where on the mic pin for a trc 447 thank you

I don't know which mic you're trying to wire to this radio. The colors of the wires in the mic cable may change from one mic to another, so relying on the color is not reliable. Usually you refer to these connections as Pin1 to a Signal or Function; or Jack Pin1 to Plug Pin3. No one assumes a color will always be used to connect Pin1 to TX (transmit).

With that said, I found an answer on FixYa from someone that answered the question some time ago like this:

HERE IT IS THE CORRECT MIC WIRING FOR THE REALISTIC TRC 447.

1.)Audio
2.)RX
3.)TX
4.)CH.Down / Shorted to Ground
5.)Ground
6.)Ch.Up / Shorted to Pin 4

Be extremely careful when wiring this radio! pin 4 and pin 6 carry voltage shorting these to the wrong place can result in serious damage to your radio.

Lastly, since I doubt what was provided above is going to help you very much - you can review all the info ever printed by Realistic on your radio, here. There's a wealth of info on this page and you should be able to find what you're looking for in it. You're looking to find the pinouts of the radio to the pinouts of the mic.

If you ever have to disconnect a multiconductor cable from a connector, and you don't have the time or means to write the colors down, it is better to simply cut the cable - leaving all the colored insulation of wire ends soldered / still secured to the connector. When you are ready to do the replacement of the connector or cable, you've got the wiring order in place still, and can make the new connections one at a time at your leisure.

Good luck!
