The most recent version of QRS supports 'time synchronisation'. I am not a

The ideal way would be to know the exact time (i.e. phase) and frequency of
the audio tone, so that to implement a matched filter, but this requires
IMHO a Rubidium standard at least, an item not commonly found in the average
OM shack (not in mine anyway).
