and one for FT4 (MSHV e.g.)
M = only members
of any digital mode club, at least 2 bands and 2
confirmed modes using a single TX with no more than
100W out.
If you do not meet the above
conditions, please choose one of the 3 categories
below, otherwise the referee will do this after checking the
confirmed QSOs.
Competitors from all M
categories will transmit as
follows:
For
the RTTY45 and BPSK63 :
RSQ + serial
number starting with
001+
letter "M"
(E.g. 599 001M ) and for FT4: RSQ
+ abbreviation
"ME" (E.g.
579 ME).
In
the contest
log the
control will
be noted for
QSO's in
RTTY45 and

These competitors can
also opt for one or more of the categories below if they have
made at least 125 confirmed QSOs in each of these
categories,

other mode of working) and in the log will be entered e.g. CLUB: PDCC # 123.

The
members of the digi mode club are not obliged to
participate in the M categories, but in this case they
will no longer send the abbreviation "M"
and will follow the
rules imposed on the category they have chosen.
- If you are not a member of a
digital mode club but want to participate in category M,
before the start of the contest you must

8. Scoring
QSO Points:

Multiplier:
Each
different prefix counts once on each band, with the exception
of all prefixes from your own country which does not count as
a multiplier.
The score on each log (mode) is
represented by the sum of the points from all bands multiplied
by the sum of the different validated prefixes,
The score for the contest is obtained by
adding up the scores obtained in the competitor's mode logs.
No need to calculate the score. This will
make the arbitrage program.

The PDC uses full computer control to
verify each QSO. Prizes will be sent to the mailing address
specified in the Cabrillo log.
If the Cabrillo logo header does not
contain the EMAIL address and full name, the

If after 72
hours (but not sooner) you have not received the CLAIM
file and you are not listed in the Received Logs list, please
send the log again
but this time to digi-contest@yo2rr.ro
(If your code is in Received
logs but you have not received your CLAIM file, it means
that it has been returned to me and usually the same thing
will happen with the UBN file). Only
if you send a new corrected or completed log, the address
for this is corrected-logs@proradiocontestclub.com
The last day when you can
inform me that your call is not in the list of received logs

Result is published.
Once the final result is published,
no further changes are made to the result unless there are
refereeing mistakes or non-compliance with the rules.
After this date, please do not send the log because the activity
of making the provisional ranking has started
and pages for the net, and the
introduction of a new log implies the resumption of this
activity from the beginning.
Logs sent after the deadline will
be included in the NO LOG list and will not be verified.
11.Dupes
Dupes are contacts made with the
same station on the same band. If the first contact between
stations is valid, dupes
have zero points value. If the first
contact is not valid, second (dupe) contact is accepted.
Dupe contacts are not penalized,
so DUPES should not be marked or
deleted.
The recommended program for this contest is:
