K3: changing modes changes the frequency?

Hi
In comparing two k3s I am seeing completely different behaviour of the vfo a when modes are changed.
If for example on one radio I am tuned in to wwv 10mhz, using am, the frequency on the radio shows 10.000.000 as it should. If I then change to cw, the radio all of a sudden reads 10.000.680.
The other radio does not do this it stays at 10.000.000.
Which menu option governs this?
Can't find it!
Thanks, Tom

The Owner's Manual is your friend ...

Search for Offset - page 29:

> SSB/CW VFO Offset
> The K3 can automatically offset the VFO frequency when you switch
> from SSB to CW mode, so other stations will hear the correct CW
> pitch. See CONFIG:CW WGHT for details.

and (page 55):

CW WGHT 1.15 Adjusts element/space timing ratio (weight) for the
internal keyer.
Additional functions of this menu entry, via numeric
keypad (Advanced):
Tap 1 to select SSB -CW (default) or SSB +CW (allows
CW in SSB modes).
Tap 2 to select @ = STOP (‘@’ character terminates
KY-packet transmission; default) or @ = ‘AC’ (‘@’
in a KY packet is sent as .--.-. [@] in CW mode).
Tap 3 to select OLD or NEW QSK (default). NEW reduces
AF keying artifacts.
Tap 4 to select VOX NOR (default) or AUTO OFF. The AUTO
OFF setting turns CW VOX off on power-up, avoiding
accidental keying by attached PCs, etc.
Tap 5 to select automatic VFO offset on SSB/CW mode
change (VFO OFS) or no offset (VFO NOR, default).
Automatic offset is often used on 6 meters, where
mixed-mode QSOs are necessary during fading. Note: Pitch
matching will be more accurate if USB is paired with CW REV,
and LSB with CW normal.

Hi
Yes but it wasn't friendly today. I looked but I guess I overlooked this.
Thanks, Tom
