K3 Diversity and mode changes

[G3TCT]

I'm playing with diversity operation and find that when I change modes say from usb to cw, the main rx changes frequency slightly to keep the received tone the same (as expected), but the sub rx doesn't change frequency.  
This is not a big deal because I can tap A->B to force the frequencies equal, but does anyone know if this is usual or if I have something set wrong?

f/w 3.77

TIA
Graham

Graham,

When in diversity receive, VFO A is the VFO for *both* the main and the
sub.  While in diversity, VFO B only serves as the transmit VFO if SPLIT
is active.  Tapping A>B is really a "no-op" step in diversity (unless
SPLIT is on and you want to move the TX frequency to the RX frequency.  
See page 37 of the K3 manual.

Thanks for the clarification. I hadn't realised the sub tracked the main rx
"invisibly" as it were - I was expecting VFO B to change, but now it's
clear.
Great!
Graham
