[Elecraft] Re: K3 CW-in-SSB mode: force CW VOX?

[Alexandr Kobranov]

Let me put as illustration partial cut&paste from TS-480 manual:

------------------

Menu Item 40. - 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.

and

Menu Item 41. - AUTO CW TX IN SSB MODE - OFF/ON

If you operate both SSB and CW modes, you can
configure the transceiver to change the operating
mode from SSB (USB or LSB) to CW and then
transmit in CW mode automatically when you operate
the CW keyers.
Note: You must switch the CW Break-in function ON to change the
mode and transmit in CW mode

----------------------------------
I suppose both examples are what we are talking about.

Both of them are useful and applied on more rigs but the description 
in TS-490 manual is very illustrative IMHO.

Hope it can clarify what is going on for those of us never need this.
