5. General Rules
5.1. All transmitters, receivers, and amplifiers must be within a single 500-meter diameter circle. Antennas must be physically connected by RF transmission lines to the transmitters and receivers, except as described in 5.1.5.

5.1.1. Remote operation is permitted if the physical location of all transmitters, receivers, and antennas are at one station location as described in 5.1. A remotely operated station must obey all station license, operator license, and category limitations. The call sign used must be one issued or permitted by the Regulatory Authority of the station location.

5.1.2. The use of QSO finding assistance (DX cluster, CW Skimmer etc) is allowed for all entries.

5.1.3. The use of any calls other than participant’s for any reason including keeping the run frequency on any band, making schedules, DX-spotting, moving the multipliers is prohibited.

5.1.4. Self-spotting or soliciting contacts by any means other than amateur radio is prohibited.

5.1.5. The use of one and only one remote receiver located within 25 kilometers of the main transmitter site is permitted, in addition to the receiver at the transmitter site is allowed for all entries.

5.1.6. The use of any remote receivers other than described in 5.1.5 are prohibited. Violators will be subject to disqualification.

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 categories: one person (the operator) performs all operating, logging and spotting functions. Any assistance will result in reclassification into the Multi Operator category or disqualification at the discretion of the contest committee.

5.3. MOST stations are subject to a 10 minutes band change rule. Mode change within current band is allowed without limitations.

5.3.1. Start time is determined by the time of the first QSO made on the band. The band may be changed after 10 full minutes have elapsed.

5.3.2. Only one signal can be transmitted at any given time. Exception: two signals on two different bands are allowed if (and only if) the station on another (and only one) “multiplier” band works a new multiplier.

5.3.3. The “multiplier” transmitter is subject to its own 10 minute rule for band changes as described in 5.3.1.

5.3.4. Contacts which violate band change rules, should be clearly marked in the log with an X-QSO: key (as per 11.11 ). They will neither be counted nor penalized for an entrant, but will be counted for the station contacted.

5.3.5. Tampering with the QSO time to comply with the 10 minute rule (“rubber clocking”) will result in disqualification.

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 be worked twice per band (CW and SSB) regardless of which transmitter is used.

5.5. MM (Multi Op, Multi transmitters): A maximum of six transmitted signals, one per band at any one time. All equipment (transmitters, receivers, amplifiers, antennas, etc.) must be located in same DXCC entity, including remotely controlled equipment. Six bands may be activated simultaneously. Use a separate serial number sequence for each band. Limits in 5.1 do not apply.

5.6. All MIXED categories entrants can work the same station twice per band (CW and SSB).

6. Exchange:
6.1. Non-Russian stations: signal report + QSO number, starting with 001.

6.2. Multioperator (MOST, MO2T, MM) may alternativley use separate serial numbers for each band.

6.3. Russian stations: signal report + oblast code as per attached list.

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.

7.2. 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 (UA2F), Franz Josef Land (RI1FJ) and Russian Antarctic stations (RI1AN) each count as a separate DXCC entity and a separate Oblast (double multiplier) with Kaliningrad counts as European Russia for scoring purposes.

7.4. Maritime mobile (“/MM”) stations do not count as multipliers and score 5 points for all participants.

7.5. SWL points are calculated along the same principles as described in 7.1 and 7.2.

8. Dupes
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, then second (dupe) contact is accepted.

8.2. Dupe contacts are not penalized; they do not have to be marked in the log. All entrants are strongly recommended to leave DUPES in the log.

9. Multipliers
There are two types of multipliers:

• One multiplier for each different oblast contacted on each band, including UA2F, RI1FJ and RI1AN as per 7.3.
• One multiplier for each different country (DXCC entity list + WAE multipliers list) contacted on each band.

10. Final Score
10.1. The final score is the result of the total QSO points multiplied by the sum of oblast and country multipliers.

11. General Log Submission Requirements
11.1. Logs are accepted in CABRILLO file format only.

11.2. Filename of your log should be yourcall.log or .cbr. Example: UA1AAA.log.

11.3. If a competitor claims two separate bands in the SOSB category (as per 3.1 ) these two bands should be clearly marked. Example: CATEGORY-BAND: 10m, 15m.

11.4. Russian stations will include their RDA in the LOCATION: field.

11.5. Web upload is the only method of log submission. Web upload of logs is available at: http://www.rdxc.org/asp/pages/wwwlog.asp.
