Hello list, I am having a strange thing happen on my 71a which I 
must have caused but can't figure out how to undo.  When I am 
listening on my 71a,  and have the right VFO on a memory either 
VHF or UHF and the left VFO on a different memory, and have both 
squelch knobs turned off, the memory that is selected will 
dominate, meaning that if I turn the volume of the dominant VFO 
up it will mute the squelch sound of VFO b.  The opposite also 
hapmens.  I know that it is possible to have both VFO's work at 
the same time without either one being muted unless you transmit 
on one and the other is listening on the same band.  Does that 
make any sense? The mute button, righthand most button on the 
bottum row,  will select between a and b VFO but when both are 
supposed to be active, they are not.  I don't know how to explain 
this any better, but maybe one of you TMV71A owners will know 
what I'm talking about.  Jim WA6EKS
