I now have a pair of OmniVIs and would like to use them in a sort of
poor-man's SO2R. Actually I
believe what I want to do is called SO2V but will actually be with two
radios. What I would like to do
is to have both radios functional on receive, and have the alternate
radio's (radio B) T/R PIN diode switch activated when the primary
radio(radio A) is transmitting, thus protecting the front end of the
alternate radio (radio B). Thus the question: Does the PIN diode
switch activate a) when the key is pressed/entered, b) when the signal
from the QSK loop / amp is returned, or c) at some other time. The
easiest solution would be to use radio A's QSK loop in some way to
activate radio B's T/R PIN switch. As the control logic is inside a
chip rather than in hardware, staring at the schematic does no good.
Any takers for this question??
