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

Hi gang. 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
