3.1 The participant can operate and enter in two different single band 
categories. This allows a station, for example, enter two logs for 10m and 80m 
and have both count towards awards. 
3.2 Single Band entrants operating other bands during the contest are 
encouraged to submit their logs for more than one band to aid in the log 
cross-checking process. 
3.3 All entries separated by World, European Russia, Asiatic Russia. 
4. Team Competition4.1 OBLASTS COMPETITION (Russian 
entrants only). The OBLAST score is the sum of top ten stations scores from the 
same oblast. 
4.2 CLUB COMPETITION - between contest clubs and groups, separately 
for Russian and foreign clubs. 
4.2.1 Participants of CLUB competition may submit their score for 
their club regardless of country and distance to the club HQ. 
4.2.2 Foreign participants may submit their scores in favor of the 
Russian Clubs and vice versa. Participant’s score may be credited to one club 
only. 
5. General Rules5.1 Transmitters and receivers must be 
located within a 500 meter diameter circle. All antennas used by an entrant must 
be physically connected  to the transmitters by wires (feeders). 
5.1.1 All categories of entrants are allowed to use packet and WEB 
clusters. 
5.1.2 Using any IP net for the remote transceiving, including web 
radiostations is unsportsmanlike and the entry is subject to disqualification. 
5.1.3 Self-spotting is not allowed. Soliciting contacts by telephone, 
telex, internet, packet mail during and before the contest is forbidden. 
5.1.4 Using other stations callsigns for the following - keeping the 
working frequency on the other bands, making schedules, DX-spotting, moving the 
multipliers to the other bands - is prohibited. 
5.1.5 The use by an entrant of telephones, telegrams, Internet, packet 
to solicit contacts during the contest (self-spotting) is not allowed and forces 
to disqualification of an entrant. 
5.2 Single Operator participants may change bands and modes without 
restrictions. Only one signal can be transmitted at any given time. 
5.2.1 Single Operator: Those stations at which One person performs all 
of operating, logging, and spotting functions. 
5.3 MOST stations are limited by "10 minutes" rule. Start time is 
determined on the first QSO made on that particular band. Only one signal can be 
transmitted at any given time. Exception: two signals on different bands are 
allowed if and only if the station on another (only one) “multiplier” band 
picked up a new multiplier. This “multiplier” band should also be changed on “10 
minutes” rule. Contacts, violating both rules, should be shown in the log, they 
will neither be counted nor penalized for an entrant, but counted for the 
station contacted. 
5.4 MO2T (Multi Op, Two transmitters): A maximum of two transmitted 
signals at any time on different bands. Each transmitter may make a maximum of 8 
band changes in any clock hour (00 through 59 minutes). For example, a change 
from 40 meters to 80 meters and then back to 40 meters constitutes two band 
changes. Both transmitters may work any and all stations. A station may only be 
worked twice per band (CW and SSB) regardless of which transmitter is used. 
5.5 All of MIXED categories entrants can work the same station both CW 
and SSB. CW contacts on SSB portion of the band, and SSB contacts on CW portion 
of the band are prohibited. 
6. Exchange:6.1 Non-russian stations: signal report + QSO 
number, starting with 001. 
6.1.1 MOST (Multi Op, All Bands, Single transmitter)can use separate 
serial numbers for each band or chronological serial numbers. 
6.1.2 MO2T (Multi Op, Two transmitters) MO2T (Multi Op, Two 
transmitters) can use either separate serial numbers for each band or separate 
serial numbers for each transmitter. Each QSO in the submitted log must have 
transmitter identifier. 
6.2 Russian stations: signal report + oblast code (two letters). 
Alternative oblast codes are allowed. 
7. QSO Points. 
7.1 Russian stations:
- QSO with your own country (Russia on your continent) – 2 points,
 - QSO with Russia on another continent – 5 points,
 - QSO with a different country on your continent – 3 points,
 - QSO with another continent – 5 points.

7.3 Kaliningrad (UA2) is a separate DXCC entity and a separate Oblast, 
but points for QSO with Kaliningrad are counted as for European Russia. 
7.4 /MM stations are not the multipliers, but worth 5 points for any 
participant. 
7.5 SWL stations must copy one or both exchange numbers, points are 
scored on common rules. 
8. Dupes8.1 Dupes are contacts made with the same station 
on the same band and mode. If the first contact between stations is valid, dupes 
have 0 points value. If the first contact is not valid, second (dupe) contact is 
accepted. 
8.2 Dupe contacts are not penalized; one does not have to mark them in 
the log submission. Moreover, entrants are strictly recommended to leave DUPES 
in the log file. DO NOT DELETE DUPES! 
9. Multipliers

- A multiplier of one (1) for each different oblast contacted on each band.
 - A multiplier of one (1) for each different country (DXCC entity list + WAE 
multipliers list) contacted on each band. 
 
9.2 Different Russian Oblasts are: Franz Josef Land (R1FJ) and Russian 
stations in Antarctica (R1AN).
