[Elecraft] K3: changing modes changes the frequency?

[Joe Subich, W4TV]

The Owner's Manual is your friend ...

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.
