hello all,

has anyone built with any degree of success a station mic switch? i
would like to somehow interface all the rigs in the shack to my heil mic.
if someone would be so kind as to send a schematic and parts list of what
they built i would appreciate it.

BTW, all the rigs i wish to interface to the mic have the same
impedence.

Mike -

Projects like this appear regularly in the amateur literature.

Chris Cieslak, AA9HD had a November 1997 QST article, "A simple
microphone/TNC/SSTV Switch" (Adobe Acrobat available to members from ARRL
web site)

The article references a Radio Shack multi-pole switch (275-1386A) -- which
may no longer be available. An old manual serial or parallel connector
switch can be salvaged (tons of this stuff in junk yards allover country)
for the manual (multi-pole) radio switch.
