Can the K3 do full duplex in the same band? Elecraft's FAQ seems to indicate
that they do not support this mode:
"Can the subreceiver provide unbroken audio using any antenna input
while the K3 is transmitting?'
"This is "full duplex" operation, which is very difficult to do inside
a single cabinet. However, it may be possible if you're using the
transverter I/O (0 dBm TX power). We'll be testing this case and will post full
specs later."
Does the firmware support this?
I am very interested in your experiments. Will you need to modify the DEMI
transverter IFs? - Duffey
