[Elecraft] SSB<>CW VFO offset

[Alexandr Kobranov]

What we are talking about is as already published in "wish-list" on 
zerobeat forum:

FREQUENCY CORRECTION FOR CW - OFF/ON
If you operate both SSB and CW modes, you would
sometimes use SSB mode (USB or LSB) just to
watch and listen to CW signals. It is fine just to
monitor those CW signals but you have experienced
that changing the mode from SSB to CW results in
losing the target CW signal. This is because the
frequency on the display always shows the true
carrier frequency for all modes. If you want the
transceiver to shift the reception frequency to trace
the receiving CW signal when changing the mode
from SSB (USB or LSB) to CW, switch this function
ON. The transceiver shifts the reception frequency
when changing the mode from SSB to CW, so you
can still hear the target signal and instantly transmit
the signal in CW without adjusting the frequency.

I also hope in future revision of fw :-)
