Before I got the real mic for the TBX I cobbled this thing together with a
T-1 telephone cartridge that gives the high output needed for the TBX. If
you are going to try to adapt this to another transmitter, note that the
pushbutton on a TBX microphone is not a T/R switch, it opens and closes the
microphone circuit. You would have to rewire.
$20 gets it to your door in the USA.
