Need to wire an Astaic 575 m6 microphone to a yaseu 857 but dont no wat colors from the mic go to which pins on the radio

look up microphone wiring diagram for your cb and mic. more than one way to wire, depending on mic and cb having 4 or 5 on plug end. write down mic numbers and cb plug numbers. if audio on mic is 3 and cb is 4 put 3 on 4 pin check each wire. using power mic make sure red and black wire are on the right pin, can damage radio or mic or both.

ALTAI PWR MIC - black/braid= earth, red=RX, white=TX, Yellow=MODASTATIC - blue/braid=earth, black=RX, red=TX, white=MOD, Yellow=Spare
SIRTEL ECHO MIC CBE 2002 - black/braid=earth, blue=TX, white=RX, red=MOD007 POWER MIC - brown/braid=earth, green=RX, white=TX, blue=MODSADELTA EC 980 - braid=earth, green=RX, brn=TX, white=MOD
or braid=earth, black=RX, blue=TX, white=MOD

its a 5 pin which all radshack radios are and they are all,99% anyway, wired the same . So take an old radshak mic apart at the plug and see how it is wired then experiment from there.

( 9 Stand ) Astatic D104 to Yaesu FT 990

Pin 1 is White
Pin 2 is Red
Pin 7 is Shield/Blue combined

dont worry about colors.. match mic pin to the microphone ptt switch for any radio.

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.

it depends on what kind of radio youre using and how many wires are in the mic cord

THE YELLOW I BELIEVE IS THE AUDIO LEAD WITCH GOES TO PIN 2 AND SHIELD IS PIN 1 PIN 3 IS TRANSMIT AND 4 IS RECEIVE

this radio is made by PEIRCE SIMPSON and is wired like a cobra.
pin 1 shiels or ground
pin 2 is audio
pin 3 is transmit
pin 4 is recieve

shield is a bare wire wraped around the audio wire.i dont know the colors of the wires in the echo mic.the transmit wire will have contiuity with the shield wire when the mic is keyed that wiregoes to pin 3 . there should be 2 wires left. check these wires one at a time with the shield wire one will have contiunity . this wire will go to pin 4 recieve.the other wire will go with the shield wire on pin 1
this is the way you find how it wires. it will take an ohm meter to find whice wire goes where.

Pin 1 is Shield(most mics this wire is bare copper) Pin 2 is Audio wire(most mics this wire is white) Pin 3 is Transmit(most mics this wire is red) Pin 4 is receive(most mics this wire is black)
