This is why panadapters and waterfalls should never have been allowed in the
unassisted category. And why I have never used them.
I don't doubt their legitimacy in the operating category based on the rules
as they are currently written. But I said "back then" that it was a
mistake. And still feel that way today.

Yes, even when unassisted there is no need to "turn the knob" to tune in
stations on the second radio. There is also no need to ever tune
sequentially (the first pass up or down a band Steve mentions) to identify
signals manually. Sometimes I do tune with the 2nd radio knob, but with
so2sdr (available since 2010) I can just click on the signal and jump there
directly. Or press the ctrl+arrow keys to automatically tune the second
radio to the next higher or lower signal.

A competent, unassisted, operator will manually fill in the bandmap
going up (or down) the band, filling in callsigns as they go. There is
now software, such as NaP3 or Waterfall Bandmap, which superimpose a
waterfall or spectrum display on the bandmap. After the operator does a
pass up (or down) the band, each waterfall or spectrum trace will have a
callsign associated with it. A good, unassisted, operator will keep an
eye on the waterfall or spectrum trace, When a new trace appears,
without a callsign associated with it, the unassisted operator can
simply mouse-click on the trace, and send the radio to that frequency.
