That must be a different CCW than I used as a government employee back in
the mide 60s. I dont remember a lot about it, except we had CCW equipment
in our receive site, and were copying from at least two
SV0WPP VS6DD N7DC/YV5 G5CTB all
DX 2-6 years each.

From my perspective, the thing that was so desirable for amateur radio,
was the ability to use the computer to do the DSP and make it possible
to come up with these newer modes at relatively low cost.
Ray Petit, W7GHM, invented CCW in the early 1970's, but it required
extremely accurate timing

Vojtech,Using fldigi on linux you can send CW via either your key line or via the sound card. Apparently the problem with using the sound card is possible poor opposite sideband suppression with filtering SSB generation schemes, which can result in a CW signal on the opposite sideband. I am usin

I am thinking of learning my SW+40 to talk digitally. I know of only
two digital modes that may be exercised on this TRX without any
hardware modification: morse and feld hell. The third possibility
would be RTTY, but it would need to modify the TRX slightly. Although
it may be done on SW
