Hi,

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.

One important point is to make sure that the microphone ground (not the
cable screen) is treated as a separate 'live' wire throughout and not grounded
in the switch only in the rigs. Failure to do this can result in hum loops.


Cheers - Joe
