[TenTec] Orion shown with Heil mike

Interesting.  I just read from one "poster" to the reflector that his Heil
mike didn't work well with his Omni.  Then I read from another this evening
that his Heil works great and he always gets good reports.  Wonder just who
is wrong?  Or better yet where's the wrong.

First, most lo Z mike are never 600 ohms.  They are more likely 150 to 250
ohms and for long cable runs, 50 ohms is well accepted.  And yes they are
balanced to minimize humm pickup.  The professional output line level
signals are referenced to 600 ohms and most always balanced.

Most all that I've encountered in ham radios have unbalanced
inputs.....being Hi Z.  That's anything above say 10K ohms or above.

Wonder what the Orion will do "audio wise" on AM.  Yes there's some of us
that do run AM still today.  See my little AM rig under my call on QRZ.COM.
I use a Paragon for the AM receiver and the exciter for the AM transmitter
and I use an OMNI VI+ for the SSB and CW station.
