5. General Rules
5.1 All station transmitters, receivers and antennas must be located within a 500 meter diameter circle. All antennas must be physically connected to transmitters and receivers. The use of receiving equipment outside the 500 meter circle is considered unsportsmanlike and violation of this rule make the entrant subject to disqualification.
5.1.1 A station which complies with Rule 5.1 may be operated remotely via network connection in political entities where remote station operation is legally permitted. A call sign appropriate for the DXCC entity where the station is physically located must be used.
5.1.2 All entry categories are allowed to use packet and/or web clusters for spotting assistance.
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.
6.1 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.
- 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.
- Non-Russian stations:
- QSO with Russian station – 10 points,
- QSO with your own country – 2 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.
8.1 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!
- Two types of multiplier will be used:

9.2 Different Russian Oblasts are: Franz Josef Land (RI1FJ) and Russian stations in Antarctica (RI1AN).
