José - I am looking at the rules at http://www.cqww.com/rules.htm in the
pdf file link. Under single op:
A. Single Operator categories: For
all single operator categories, only one
person (the operator) can contribute to
the final score during the official contest
period. QSO alerting assistance
of any kind (this includes, but is not
limited to, packet, local or remote
Skimmer and/or Skimmer-like technology,
Internet) places the entrant
in the Single Operator Assisted category
I do not see anything about decoding, just alerting. Am I missing
something?
Also, CW decoding has been available for many years in Writelog. I am
not aware of this being addressed in the past.
