I picked up a Heil BM-10 for hands-free operation but decided to make
my own mic adapter rather than pay extra bucks for Heil's version.
I'm not sure which pins to connect and would like some
clarification. Does the Heil plug tip go to +5 and the ring go to
ground? Also, for PTT I'm assuming I would place a switch between
that line and ground?

I've check the message archives and files area but couldn't find any
good confirmation on my assumptions.

Thanks and 73. KB0LUR, Paul
