Another problem with soundcards is that of timebase accuracy, and in some cases even stability. Many cases of severe errors were identified by G3PLX during the development of PSK31 In the better card
Everybody who is involved in extreme narrowband mode such as QRSS and DFCW will confirm that signals that are 10 to 20dB below the 'normal CW' detectable level can still be copied and lead to a QSO.
Keep it SIMPLE all that is required is a good cw operator at each end with well filtered, selective symmetrical EARS able to read morse through qrn and qrm and a steady hand for sending. [snip] Are

G3KEV replied: Tell me Rik, why is there no qrss(LMCW) when the band is noisy like lots of qrn/static about. My ANSWER after monitoring and experimentation with spectran is that the qrn chops the lo

G3KEV replied: On the contrary, Had you been listening today you might change your mind. I tuned to a weak steady carrier and the QRN was so consistant that it chewed it up completely. Not just inte
