probably  will try to rig up some sort of squelch system, and probably outside
the  various receivers. In particular what I want to do is be able to monitor 
a  couple
of HF utility frequencies and have them break in over SWL broadcasts  when 
there's
something happening, this is more of a prioritizing rather  than a simple 
squelch
scheme. Still, I'd like to see how they thought it  would be done in the 
R-390A.




I haven't tried to do a squelch, but it shouldn't be too hard.  You've  got 
the AVC line and the diode load jumper available on the rear terminal  strips, 
so you could use the AVC voltage level to switch the audio on or  off.  Let us 
know how you fare
