[Elecraft] Panadapters - need for bandmap capability

[Barry N1EU]

I'm offering this as food for thought.  It seems that one important feature
that panadapters (SDR, LP-PAN, P3, etc) lack is the inability to tag a
spectral trace with a callsign to mark its identity.  For example, check
this mockup:  http://n1eu.com/bndmp_spec.jpg

If I qsy to a trace I see on a busy band, I want to be able to ID that trace
so I don't keep coming back to it.  And those ID'd callsigns by trace
frequency would constitute a bandmap.  Ultimately, this bandmap could have
the same functionality as the bandmap in a contest logger (e.g., N1MM).
It's just rotated 90 degrees and has freq interval spacing aligned with the
panadapter waterfall display.  This ID'd panadapter functionality would be
immensely useful in both unassisted and assisted contesting.  I realize that
development of this capability might require unique collaboration between
several software/hardware vendors but it would fundamentally enhance
panadapter-centric operating.

(CW Skimmer provides some of this capability, but it's totally limited to
callsigns decoded by Skimmer, not by the operator, etc.)
