I am in need of a modern, simple VOX circuit. The last circuit I
located was vintage 1980 and I would hope there is something simpler
than 8 transistors! Maybe a couple of IC's ??? If you have any circuits
of recent vintage for VOX circuits, I would like to see it. I need this
circuit for keying a transmitter from an external command receiver
(scanner). Supply voltage of 12VDC and 12VDC relay to key PTT.
If you could send me a photocopy or give me a reference, I
would appreciate it. I can be contacted at KA2RAF@NN2Z.NJ or at the
following postal address:
