6. Categories: (one of the categories

C&T, M, M-BPSK63,
M-FT4, M-RTTY45, SO-LP, SO-10m, SO-15m, SO-20m, SO-40m,
SO-80m, SO-BPSK63, SO-FT4, SO-RTTY45, SWL.
I suggest you use two contest programs, one for
RTTY45 and BPSK63 (M1MM e.g.) and one for FT4 (MSHV e.g.)
C&T
= All club
stations (with one or more operators) as
well as Teams operated from the
same location by several
operators who will use a single callsign and TX
on all bands, and the power is the authorized
one.
These stations can only participate in the C&T
category, otherwise they will be included in the
Check Log (CL) list.
Competitors in this category will transmit RSQ +
serial number starting with 001 (e.g. 599 001)
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.
Club stations or
teams cannot participate even in category M. If they do so, they will be included
in the CheckLog (CL).
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
BPSK63
starting with
599 001M and
for FT4 with
579 M
(without
serial number)
Competitors in this category can
participate in one more of the 3 categories below if
they have made a total of at least 250 valid QSOs
and in the second
category at least 125 valid QSOs.
M-BPSK63 ( Members only
BPSK63, regardless of the number of bands),
M-FT4 ( Members
only FT4, regardless of the number of bands),
M-RTTY45 ( Members only RTTY45, regardless of the number of
bands).
Competitors from one
of the 3 categories above can opt for more M-mode
categories provided that in each of these categories they
make at least 125 valid QSOs,
which will be
verified following verification of the contest logs.
If
you transmit in the form above must participate in
categories M (Members), and the log will specify the name of the digital mode Club which
also
includes the membership number (not clubs of
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
to become a member of a club
with specific digital modes. If you do not resolve, send me
an email asking you to become a member of the PDCC, otherwise you will
have gone to the Checklog. PRO DIGI CONTEST CLUB (PDCC) was
founded with one purpose, to facilitate your participation
if you wish in the M category of the PDC.

CDG, DMC, EPC, EU-PSK, FHC, FT8DMC, OBC, PDCC,

8. Scoring
QSO Points:
For QSO with own DXCC country: 1 point;
For QSO with another DXCC

For QSO between DigiMode-Club
members (M category) and non-members receive : 2 points extra-bonus;

members (M category), they receive: 6 points extra-bonus.
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.

after the publication of the results, the certificates in PDF
format will be found on the website of the contest at the

Contact is valid if a time difference
in both logs does not exceed 3 minutes. Please don't
forget to set your computer's clock before the Contest!
Logs sent after the deadline will be
included in the NO LOG list and will not be verified.
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
competitor will not receive the CLAIM and UBN
files,
and if the specified postal address
is incomplete or does not exist, will not receive the prize
obtained.
In addition, M-category
competitors must indicate at the top of the Cabrillo log ,
CLUB: (specific to the DIGI club) with Member number
without which it cannot be included in the
ranking.
The deadline for sending logs is
Saturday, 6 (six) days after the end of the
contest until 20:00 UTC. (January 24, 2026)
Logs will be sent to: digi@proradiocontestclub.com
. Please also follow the RECEIVED LOGS page.
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
or there have been errors regarding the category in which you

the 7th day after the end of the competition when the Provisional
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:
- N1MM
Logger + for BPSK63 and RTTY45, from
UDC we use the PCC module for PDC as
well..
- MSHV
(PRO
DIGI
Contest) for the FT4 contest with
Exch seting: DX for Non-members and
ME for Members. MSHV
or another
program that can be set for this contest.
12. Arbitration

for a category to which the rules do not allow, the referee has
the right to change the category according to the regulation.

correspondent is not received, the respective QSO is canceled
with the exception of callsigns that exist in at least 15
logs received from at least 3 different countries,
- if the QSO is not confirmed in the
correspondent's log or the difference between the times in the
logs exceeds 3 minutes, the QSO is canceled,
- if there are mistakes in the call,
incorrect RSQ or serial number, the QSO will be cancelled,
- if the Band or Mode
differs from the correspondent's log, the QSO will be cancelled,
