I don't know if this has been tried before, but I just tried it and it

I recorded some 578 seconds of audio to hard disk at 7200 samples per sec.

Seems really a good idea, which could attract also the
die-hard CW-must-be-copied-by-ears crop around.
Just one simple question : why 7200 samples/sec ? It is not a standard
sound card sampling rate. Is there a specific reason for this sampling speed ?
Perhaps Bill was using an external A/D converter. For the technique to
become widespread and accepted by many (all), it shouldn't rely on an
ad-hoc hardware. Modern sound cards have superb A/D converters,
so why not use them ?
