I did a lot of digging around. Your FT-301 is a nice radio. However the service manual does not have the mic "pin out. " The Ham Forums do not have the mic wiring either. I did find that almost all mics are not wired the same as the Yaesu. Could you just buy a Yaesu mic? Sorry I cannot find this.

SOURCE: dm 452 microphone

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.

I want to wire my superstar dm452 power echo mic to my realistic trc 465 am ssb and need to know what color goes to what pin?


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.
