[Dx4win] Deleting a large number of QSOs

[Karl Oyster]

Hi folks,

I won the booby prize today.

I was importing my CQWPXRTTY log this morning and managed to 
import it into my K1KO log rather than the log for the callsign I 
actually used (NQ1W), our club call.

How can I reliably remove those 501 contacts from my K1KO log 
without taking anything else with them?  I looked at the 
QSO>multiple QSO operations>delete approach, but I can't figure 
out how to get just the contest QSOs out of the log without taking 
others, too.  I didn't want to experiment as I have about another 
400 or so QSOs which are between the ones I want to delete and the 
end of the log.

I'll appreciate very much any direction I can get.

Thanks and 73,

Karl,K1KO
