Hello Staf,
From a technical point of view, there is only USB and LSB in a
receiver, "CW" is one of these with additional filtering (and a
frequency offset added, the "pitch", usually something like 650...800
Hz). To use your receiver in "CW" mode, you need to find out if that is
in fact "USB" or "LSB", and add (or subtract) the CW "pitch" to the
display frequency offset. Some rigs have a "CW reverse" mode. What it
is, depends on the manufacturer. My old kenwood uses USB for CW and LSB
for "CW reverse".
This principle works for all of the mentioned programs. All you need to
know is the exact CW "pitch" frequency (which is very precise for
digitally controlled rigs).
For transmission, your TRX would have to be switched to USB or LSB anyway...
Best regards,
Wolf DL4YHF .
P.S.: Thanks Teo for the QSO's - a new one for me, and a new one for DF0WD !
Regards,
Wolf DL4YHF .

Hello Alberto,
Why not include in JASON and SPECTRUM the position A1A? Now there's
USB and LSB but I use all-time A1A with a bandpass filter (IF) from
100 Hz.
