Romania
Regulations in progress (if you have any
proposals regarding this regulation, I am waiting for them until
November 30, 2025)
1. Object
Making radio QSOs with as
many stations as possible in three digi-modes.
With the same station, you can make three
valid QSOs in each band, one in each mode (FT4, RTTY45 and
BPSK63)
2. Contest Period
Every year, the third
full weekend of January.
In 2026, start Saturday 17
at 12:00 UTC until Sunday 18, at 11:59:59 UTC.
(24 hours)
3. Bands
80m, 40m, 20m, 15m and
10m, ( Band segments allocated for the
working modes used in the contest will be used).
The recommended dial
frequencies for FT4 (all USB) are:
80m:
3576 kHz; 40m: 7047.5 kHz; 20m: 14080 kHz; 15m: 21140
kHz; 10m: 28180 kHz
Changing bands can only be changed after
a break of at least 5 minutes
For non-compliance with this
provision of the competition regulations, the
penalty applied each time will be 1%
of the total score obtained.
4.
Mode
BPSK63, FT4 and
RTTY45. (in
log mode it is noted like this: BPSK63 with PM, FT4
with FT4 and RTTY45 with RY) and not otherwise.
With
the same station, QSOs can be made on each band in the
three modes but only one contest log will be sent.
Changing modes can only be changed after a break of
at least 5 minutes.
For non-compliance with this provision of the
competition regulations, the penalty applied each
time will be 1% of the total score obtained.
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.)
Competitors in all M categories may also
opt for one or more of the M-SB categories below
if they have made a total of at least 250
valid QSOs,
and in each category at least 125
valid QSOs, which will will be
confirmed following verification of the contest
logs.
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)
In the contest log of all
M categories the name of
the digi club to which they belong and the membership
number will be specified
(not clubs of other working modes or
radio clubs) and at the
head of the log (e.g.
CLUB: EPC#99999) will
be entered.
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.
If
you are not a member of a digi club but want to
participate in category M, follow the rules for
this category, and in the contest log enter
in the CLUB: PDCC#1000 and you
will become a member of the PDCC until the final
result of the contest is posted online.
PRO
DIGI CONTEST CLUB (PDCC) was
founded with one purpose, to facilitate your
participation if you wish in the
M category
of the PDC.
Ex. Some DIGI clubs: BCS,
CCB,CDG, DMC, EPC, EU-PSK, FHC, FT8DMC,
OBC, PDCC, PKRWG,

which will will be confirmed following
verification of the contest logs.

is the authorized one.
These stations can only
participate in the C&T
category.
Competitors in this
category will transmit
RSQ +
serial number starting
with 001 (e.g. 599 001)
SWL

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.

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.
9.Prizes
Shortly
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 prizes,
CLAIM and UBN file, please indicate in the Cabrillo log your

11. Arbitration
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.
If a competitor opts
for a category to which the rules do not allow, the referee has
the right to change the category according to the regulation.
- if the log from the
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,
- the penalty for not respecting the 5 minutes
break when changing bands or working mode will affect the final total score with 1%
each time,
and you can find the
list of penalties by clicking on the penalty score
specified in the ranking.
- also competitors from any category get 0 (zero)
points or are disqualifield will be included in the Check
Log (CL) category.
