AC7AC replied to N2WN, concerning use of CWr:
There is really only one reason for switching sidebands in CW: to help you
avoid QRM. If another signal is close but not zero beat with the signal you
are copying, changing sidebands (CWn to CWr or vice versa) will change the
amount of separation
Unless I have it backwards, when you are tuning in on
a signal normal CW will tune from the high side to
zero beat, in reverse you'll start hearing the signal
on the low side (ie the signal is at 7.025, you will
start hearing it around 7.0243 at a high pitch)

Julius,
You do have it backwards (assuming your BFOs are set normally). In CW mode,
the pitch of the received signal becomes higher as you tune to a higher
frequency. In CWr, the pitch goes lower as the tuned frequency goes higher.
If you want a 'mental memo' you might think that in CWreverse,
Don,
Thanks, I think I just didn't write it clearly, or you
explained it better. In CWr (I think about tuning
during SP in a contest), you go from a higher pitch
sounding signal to a bass sounding signal tuning from
the bottom of the band up.
You might fill me in, and probably others, what is the

is it like the sidetone frequency a preferential thing? I can see some use
in a contest situation for it...

CW and CWR are like USB and LSB for voice, but with CW either will work,
as nobody sounds like Donald Duck in code, hi hi. If you are bothered
by QRM (e.g., below the OM you are in QSO with, but not above, or vice
versa) switch to CWR. It may help even if you have filters switched in,

You are both right here, the K2 in CW normal mode, tunes upwards in beat on
the low bands (160m - 17m) and tunes down in beat on the higher bands. This
is due to the K2's mixing schem with low side injection for the higher
bands. But the K2 remebers the CW/CWr setting per band, so I have mine

If I am listening to 1.00 in vw mode and chenge between cw and cw
reverse - what should I hear as a difference and why? Thanks
