log header must contain one or more of the categories
specified below in the contest rules):
M, M-PSK63, M-FT4,
M-RTTY45, SO-HP, SO-LP, SO-80, SO-40, SO-20, SO-15, SO-10,
SO-PSK63, SO-FT4, SO-RTTY45, C&T, SWL, CL.
I suggest you use two contest
programs, one for RTTY45 and PSK63 (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 200
valid QSOs, and in each
category at least 100 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 any authorized power
for this modes
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 and teams
cannot participate in category M. Competitors from all M
categories will transmit as
follows:
For
the RTTY45 and PSK63 :
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
PSK63 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: PDCC#1000) 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

founded with one purpose, to facilitate your
participation if you wish in the

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.

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

with the exception of callsigns that exist in at least 15
logs received from at least 3 different countries,

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,

break when changing bands or working mode will affect the final total score with 1%
each time,
