3.3 Single Op, single band entrants may operate on other bands during the contest and are encouraged to submit their entire logs to help in the log cross-checking process. These contacts will not affect the Single Op, single band score but will be credited to other stations.
3.4 Classic entries criterias:
- Only one transceiver can be used without using a second receiver during transmission;
- Reception and transmission of call signs, control numbers and any other information necessary for conducting two-way communications must be carried out by the operator independently. The use of skimmers and DX alert networks is not permitted.;
- It is allowed to use standard short CW text messages generated by a computer or other hardware and software;
3.5 Operators applying for additional One Radio and Classic subgroups and applying for awards are required to provide an audio recording of their work at the request of the judges.

The results are summarized separately for Russian and foreign Clubs. National organizations (e.g., JARL, REF or DARC) as well as their subsidiary divisions are not eligible for the club competition. The participant’s log must clearly indicate the full name of the club in the field CLUB: [text].
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.
5.1.1. Remote operation is permitted if the physical location of all transmitters, receivers, and antennas are at one station location.
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 publicly available potting assistance (DX cluster, CW Skimmer etc) is allowed for all entries (With the exception of stations of the additional Classic subgroups).
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 is permitted during the contest.
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 other human or automated assistance will result in reclassification into the Multi Operator category or disqualification at the discretion of the contest committee.
5.3. Multi Op, Single transmitter 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 11.12 ). 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. 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. 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.
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. Multi Op 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.
7.6. Countries and continents are determined by the list of the DXCC.
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

The recording must be in a common format (e.g., mp3) and should include the audio to each ear as a separate channel. The recording must be a continuous recording (not a recording of individual QSOs). Time “off the air” (when not transmitting or receiving) does not have to be recorded. The recording may be requested by the Committee within 90 days after the log deadline to help adjudicate the log. The recording files must be provided by the entrant within 5 days of the request. Failure to submit a requested audio recording may result in the reclassification of a log entry or disqualification.

16.1. Penalty is appllied if:
· incorrectly logged calls (Bad Call);
· incorrectly logged exchange numbers;
16.2. QSO neither counted nor penalized for the following:
· QSO time difference of more than 3 minutes (except for cases in which the judges determines error as fault of the correspondent);
