Well, it was definitely a bug because there was code to prevent it that
was not working :)

Yeah, it's probably a good idea.  It's a bit of a "can of worms" because
along with the ability to keep the history, you generally also want to
be able to delete, summarize, save, etc that history.

How about for the time being, I add a flag that lets you say "keep
history" or some such.  This would stamp the time (or something) on
incoming reports so that "KK7DS" would become "KK7DS.08190906".  When
the next report from that station arrived, it would be similarly
stamped, but since it's a different name at that point, the existing
code would consider it different and not replace the old report.  This
would then let you use the existing delete-a-point function to delete a
received point in time.

It's a bit of a hack, but it's something I could do in an afternoon.
Would that be worth it?
