5.
Contest call: CQ PDC
6. Categories: (The contest
log header must contain one or more of the categories
specified below in the contest rules):
M, M-BPSK63, M-FT4,
M-RTTY45, SO-HP, SO-LP, SO-80m, SO-40m, SO-20m, SO-15m,
SO-10m, SO-BPSK63, SO-FT4, SO-RTTY45, C&T, SWL, CL.
I suggest you use
two contest programs, one for RTTY45 and BPSK63 (M1MM e.g.)
and one for FT4 (MSHV e.g.)
M = only members
of any digital mode club, with at least 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
BPSK63
starting with
599 001M and
for FT4 with
579 M
(without
serial number)
Competitors from all M categories
have the opportunity to compete in more categories if they
have made at least 250 valid QSOs in total and 125
valid QSOs for
each new category.
When making the provisional ranking, the referee will
determine whether these conditions have been met. At the
top of the log, the name of the
digital mode club to which
they belong and the member number will be specified (not
clubs of oter working modes or simple radio clubs e.g.
CLUB: PDCC # 123).
-Members of digital mode
clubs are not required to participate in the M categories,
but in they participate in a non-Members category, they
will no longer transmit the
abbreviation M, but will
respect the rules imposed on the category they have opted
for.
- In case you are not a
member of a DIGI club but want to participate in the M
category, before the start of the contest you most become
a member of a club with specific
digital modes. If you do not
solve this, send me an email requesting to become a member
of the PDCC even imediately after the end of the contest,
otherwise if you have
sent your control followed by
the particle M you will be included in the Check Log
category. Ex. Some DIGI clubs: BCS, CCB,CDG, DMC, EPC,
EU-PSK, FHC, FT8DMC,
OBC, PDCC, PKRWG,
RDR, TRC and others.
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

SO-LP = a single operator, with at least 2
bands and 2 confirmed modes using a single TX with no

bands).
Single Operator Single Band - Single TX with a power of up 100 wats
out, (regardless

stations (with one
or more operators)
as well as Teams
(regardless
of the number of modes
and bands),
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)
SWL
= Short Wave Listeners, regardless of the
number of bands and modes
The same callsign may be logged once on
each band and mode..
CL = Check Log
7. Contest Exchange:
Non members should send RST
report + serial number, starting with 001 for the first
contact. E.g. 599 001
Members of any digi-clubs, send RST
+ serial
number starting with 001 +M
(E.g 599 001M for RTTY45 and BPSK63 and 599 ME for FT4.
Only in this format will the evaluation program grant the
corresponding bonus.
See the imaginary logs below.
8. Scoring
QSO Points:
For QSO with own DXCC country: 1 point;
For QSO with another DXCC
country: 2 points;
For QSO between DigiMode-Club
members (M category) and non-members receive : 2 points extra-bonus;
For QSO between two DigiMode-Club
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
PDC RESULT ARCHIVE for
downloading and printing.

for this is corrected-logs@proradiocontestclub.com
Once
the final result is published, no further changes are made
to the result unless there are refereeing mistakes or

refereeing errors or non-compliance with the rules by the

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:
