[KX3] CW on SSB

This post was updated on .

I notice that I can often hear CW on SSB but when I switch to CW, the signal is lost. I'm talking about very strong signals, not stuff in the background. Is there something that I'm doing wrong to not be able to copy them on CW?

Re: CW on SSB

Assuming a K3 (not given in subject line):
Possibly a case where the sideband received when on SSB is opposite what it
is when switching to CW (for the given band). You could try switching to
CW-R (for reverse).

Re: CW on SSB

And enable auto-shift in the menu when switching from CW to SSB and vice
versa, otherwise you will still have to retune to get signal into the
passband again.

Re: CW on SSB

Sorry for not identifying the mode (it's a KX3) now should be reflected in the title. Anyway, thanks for the input. Switching to rev doesn't seem to have any effect. Seems pretty odd to me that I can hear the signal on SSB but not on CW (Not to say that I don't get CW signals, just that some which appear on SSB aren't available on CW). Still looking for a solution.

Re: CW on SSB

More info might help, Jim.
Band, Freq, filter width settings? For example: Is it possible you are
hearing CW at a relatively high pitch while in SSB, and when you switch to
CW, it is just outside the (narrower) filter width?

Around hear, you mostly here CW with SSB at the lower end of 40M. There is
an age old Canadian SSB net that meets right about 7.055, where there is
also a lot of CW activity...

Re: CW on SSB

In reply to this post by Oliver Dröse

This autoshift feature had the property of reporting the wrong spot
frequencies after returning to CW mode. Something like that...... I
disabled it because of the problem. This was when it was first
introduced, this possibly has been fixed in updates.

Re: CW on SSB

In reply to this post by Bruce Beford-4

I give up...didn't find any "Autoshift" in the menus of either the K3
or KX3. Is this about some other radio? Or is a feature of some
early vs of firmware long gone? I'll admit not updating the K3
lately (vs 4.81).

In doing frequency drift measurements I noted that Frequency seen in
USB mode is different than what is seen in CW mode. The shift
appears to be that of the sidetone frequency which I have set to
550-Hz for performing the temperature compensation procedure on the KX3.

To hear the test signal in USB I have to retune the VFO if I switch
from CW. I have a good ear for tone frequency so am able to tune in
the test signal in USB to match the CW sidetone frequency. That
requires moving the dial about 550 Hz. If on the wrong sideband you
will *not* hear it.

Re: CW on SSB

I believe you will find it under CW Weight in the manual

here is the snipit from the manual

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.

I think it is the Tap 5 part

Re: CW on SSB

Bill -

Which revision of the manual? I don't see anything on p. 55 that relates. The menu caption might help.

Re: CW on SSB

In reply to this post by HREFAB

The real answer here is that the K3 always indicates the carrier frequency.
There is no shift on SSB.
When changing from SSB to CW, the receive frequency is shifted by the
amount of the sidetone pitch.
The result is that the CW signal is now at an audio frequency of zero,
which neither your ears nor the K3 audio stages can detect.

The K3 does have a CW in SSB menu setting that modifies that behavior
and will allow one to send CW while in SSB mode.
