[ICOM] IC-2100 audio

[Mike Reublin NF4L]

Jay -

I didn't think to try that, and I made a new cord from some cat5 cable which seems to have solved the problem. I can't swap back because I cut a connector off the Icom cable to replace the connector, and because of the bare wire used, I can't get the new connector on.
