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.

Long shot here, but does anyone in the group know of an adapter that can be used for the Heil Pro Headset for the FDM-DUO ?

I have found several for the big name radios, but nothing for the DUO.

Thanks es 73
