SUB AF is set to nor.  I think I figured it out: the Noise Reduction  was 
set differently for each receiver.  When NR is off for both the problem  is 
gone.  I KNEW it was something stupid.  Thanks.   Sorry.

The AF  Gain dial can also be used like a balance control.  When you say 
they  are both set the same, what is probably happening is you have the 
balance  control over to the one side.   Look in the Tech Menu for a  
setting called SUB AF. The choices are nor and balance.

If you are  in balance mode and you want them to be the same you have to 
set the Sub  AF Gain knob to the middle.
