My to-do list has, for several decades, included a project for a 
switcher.  I figured I'd build a box that would take one or more 
antennas and switch the selected antenna to any of 8 or 12 outputs 
via relays (the unselected radios would have their antenna inputs 
terminated in 50 ohms or shorted to ground).  It would have a 
corresponding 8 or 12 audio inputs, with a gain control and buffer 
amp on each one, so the radio hooked to the antenna would be 
simultaneously switched to the audio output (which, in my case, feeds 
through a parametric equalizer to an audio amp and a KEF Corelli 
speaker).  One control (rotary switch, pushbuttons with lockout, IR 
remote control, whatever) would then select a radio to insert into 
the antenna/radio/amplifier chain, and the audio levels from the 
various radios could be matched.  Since I now have several ISB 
radios, I guess I'd need to make the audio section 2-channel.  And 
for use without the amplifier and external speaker, I could put in a 
headphone amplifier.

But it ain't happened yet.  Maybe when I retire. . . .

Best regards,
