This is mostly a problem if you have external transverters, amps,
pre-amps, etc. that don't take kindly to QSK operation.
My solution to this problem is to use the PTT (a foot-switch in my
case) to key the transverters, but not the rig. I'm using a stack of

This would be a fairly complex change to the normal T/R sequencer. Sorry we
haven’t gotten to it yet.
Meanwhile, there’s a simple workaround that works well:
1. In CONFIG:CW WGHT, tap ‘5’ to select “VFO OFS” mode, then exit the menu.
With VFO OFS in effect, changing from SSB to CW mode will

Subject: [Elecraft] Keying CW in SSB Mode
Regarding keying to produce CW in SSB mode – I mean this as a question, not a
criticism – why would someone want to do it? If both ends of the QSO are using
SSB then, as
RUMlogNG will use RS-232 commands to the K3(S) to send CW, PSK31
and RTTY for Mac users.

If your software provides CW via the KY CMD, as in HRD/DM780,
this is direct CW and is handled in the CW mode by the K3S.
Wayne, I have used this feature in the past with success and like it on 6M.
However, we recently switched to a setup where we need to sequence the amp
and relays, making the use of PTT (foot switch) mandatory. I turned off VOX
and breakin, but hitting the paddle in this mode still acts like VOX is

The K3, K3S, KX2 and KX3 all have a menu option for “automatic VFO offset on
SSB/CW mode change.” When this is turned on, the operator can switch from SSB
to CW mode, hit the key, and have the other station hear them at approximately
their sidetone pitch. The VFO frequency is offset to achieve

Ted, Fred et al;
As a rule using the SSB mode to send CW is very risky at best. Any hum
or distortion, meaning the smallest amount, on the CW generated audio
signal will produce harmonics of the fundamental audio tone . These
will pass through the SSB generator and sideband filter and

Using audio tones in LSB or USB mode for CW is risky business. Any
amount of over drive or excessive audio anywhere in the system,
computer, software, radio and such WILL cause problems. Same for hum or
distortion of the audio, specially if impacted by a wee bit of RF in the
audio.
I don't
All,
That may be true for CW sent by FLDIGI or another data mode application
- it simply feeds a (hopefully) single tone to the SSB generator.
The K3 CW in SSB mode is different because it is real keyed CW from the
paddles of keying input. Yes, the carrier is shifted by the sidetone
pitch
Ted, it's not a great strategy any time, and yes most likely that is
what was going on. You should see their signal when they have RF on the
audio or a hum. Not exactly meets the FCC requirements. If you are
listening with a wide filter some times you even get to hear their
Microsoft Windows
I wonder if this explains something I ran into during FD. On several occasions
– usually late at night – I was able to do some running, all on CW. Five or
six times over several hours I heard stations calling me way off my frequency.
It seemed like a Khz or more, though I didn’t measure it
