People would have thought we were nuts talking about how computers can copy 
callsigns better for us :-)  73

Though it should be noted that the LO spurious response of QSD receivers
does not appear on multiples of the frequency the signal is really on.

Direct sampling SDRs can have a spurious response that will appear on
multiples of the frequency the signal is really on.  Or AROUND the
multiple of the frequency the signal is really on, as can be seen from
RBN spots.
