[Yaesu] Weird FT-1000D problem

[John Nelson]

In the FT-1000D there's a button marked A>B which transfers the contents  of 
the main VFO to the sub-Rx VFO. Except that mine doesn't seem to do it  on 
frequencies between 7.100 and 7.200MHz. We Brits just got this  extension to 
the 40m band and I had my first QSO there this afternoon.
 That's when I came across the problem. The displayed frequency changes but 
the sub-Rx frequency seems to either stay where it was or go off to
 somewhere in the 7.0-7.1MHz region.

 Has anyone encountered this issue? It seems a very weird one to me, but 
it's real and repeatable.
