I used to use rotary switches also but once I developed the coax switches for
Hi-Z that have 80 dB of cross port isolation. I would never go back to using a
switch or single relay with a typical cross channel isolation from their on/off
ratio being only 40 dB or so. This is especially

After posting my video link about TX and RX direction switching, I have
received some emails asking about how I switch my various transmit antennas.
This morning I built another video that describes my frequency dependant
switching system that uses the Station Master band decoder.
What might be
