audio hum situation - thanks to many of you for very helpful hints.   One
thing I wanted to post for others who may stumble into this same
situation is one of the "helpful fixes" NOT to do.  Bob Heil's web page,
which was referenced somewhere along the way, describes tying the
microphone shield pin (pin 2 on the Orion) to the mic connector shell.

Do NOT do this on the
Orion!  Paul Clinton verified with me yesterday that the Orion does not
take kindly to making that connection, and I can verify that.  I'm still
working down through the options to determine which one will work, and
I'll report back when I've found the solution.

        Which is exactly the way the Heil AD-1-T is wired for
any who don't want to build the cable themselves.

I've been using this with my Heil Pro-Set including
Footswitch and PTT since last August with no problems.
Maybe someone should tell Heil that his recommendation
on the webpage above should exclude Orion (I'm copying
Heil Sound on this note).
