Re: 8-pin microphone adapter for Heil Pro Headset
Neil Smith G4DBN
Hi Ken, I made up an adaptor for my Pro-7 using a 3.5mm mono inline socket for the mic lead of my existing Kenwood, then used a short end cut off a piece of shielded Cat6 network patch lead with an RJ45. I added a 1/4 inch in-line socket for the PTT footswitch. As I use an HC-5 insert, I added a 4.7uF tantalum cap and set the boost to +12dB. That would not be required with the Heil Icom electret insert of course.
I slipped some glue-lined heatshrink sleeving over the joints and they have been in use for some time with no issues.
