[1000mp] AW: 100mp mark-v field odd problem with 2nd receiver

[Stephen Hawkins]

Bruno,

I set it for Stereo2.  In dual mode, split, I hear in my left ear what I 
should.  In my right ear I hear static.  I can change the sound of the static 
by changing the sub Receiver to a different band, or mode..  

What I see now is that the static in my right ear changes when I change bands, 
or mode, but not when I change frequency.  As I turn the dial of the Sub 
receiver, I see the frequency change on the readout, but the sound in my ear 
never changes.  It is as if the Sub receiver is stuck on one frequency per 
band, and does not change even though the read out does.
