IC27.1
FOR THOSE INTERESTED IN AN ALTERNATE METHOD HERE IS WHAT HAS BEEN DONE BY
WB4FOW ON SEVERAL OTHER RADIOS:
SINCE ABOUT 1985 MOST ICOM RADIOS HAVE PIN 8 OF THE MICROPHONE CONNECTOR
WIRED TO THE SPEAKER. THIS IS CONVENIENT FOR THE WIRING OF A TNC
AND IS USUALLY EASY TO MODIFY SO THAT RECEIVE AUDIO IS TAKEN FROM
THE HIGH SIDE OF THE VOLUME CONTROL.
ON THE IC-27/37/47 RADIOS, ON THE BOTTOM SIDE OF THE RADIO, SINCE
ABOUT 1985 MOST ICOM RADIOS HAVE PIN 8 OF THE MICROPHONE CONNECTOR
WIRED TO THE SPEAKER. THIS IS CONVENIENT FOR THE WIRING OF A TNC
AND IS USUALLY EASY TO MODIFY SO THAT RECEIVE AUDIO IS TAKEN FROM
THE HIGH SIDE OF THE VOLUME CONTROL.
ON THE IC-27/37/47 RADIOS, ON THE BOTTOM SIDE OF THE RADIO, JUST UNDER
THE AREA OF THE SPEAKER, IS A TWO PIN CONNECTOR WITH A GREEN AND RED
WIRE ATTACHED. THE GREEN WIRE IS SPEAKER AUDIO AND THE RED WIRE IS +8 VOLTS.
