RULES

1. Date: from 21.00 UTC on April 08th till 20.59 UTC on April 09th, 2023.

Stations of categories B2 and E2 may operate 12 of the 24 hours. The working time is counted from the moment of the 1st QSO. Off times must be a minimum of 60 minutes during which no QSO is logged. For all other participants, the working time is 24 hours.

2. Bands: 1.8, 3.5, 7.0, 14, 21, 28 MHz and radio amateur satellites.

3. Modes: CW and SSB.

• SPECIAL Stations operating from memorable places related to space and objects of the Russian space industry.

6. During the contest:

Participants of groups B, B2, C, E are allowed to conduct QSO through radio amateur satellites. These QSOs are counted as an additional band. Conducting a QSO through geostationary satellites is counted only in the G-SAT group.

Band plan for QO-100: 

Uplink area 2400.370 – 2400.490 MHz
Downlink area 10489.870 – 10489.990 MHz

The designation of the band in the log: 2.3G.

Categories A, B-SET, C-SET, E-SET can also make QSOs as a checklog on other bands.

Only one signal on a band is allowed at any time, except for the SPECIAL group. The simultaneous satellite QSOs and HF QSOs for categories C is authorized.

Category C must remain on the same HF band for at least 5 minutes after the first QSO has been made.

• QSO with own (P-150-C) country count – 2 points.
• QSO with a different (P-150-C) country in the same continent – 3 points.
• QSO with a different continent – 4 points.
• Satellite QSO – 50 points.

QSO points on:

• 1.8 MHz and 3.5MHz multiplied by 3;
• 7 MHz multiplied by 2;
• 14, 21 and 28 MHz multiplied by 1.

For SSB QSO, points are additionally multiplied by 2.

For SWL:

• Complete logging of one station only the callsign of the second station count 1 point.
• Complete logging of both sides of a QSO – 3 points.
• The same callsign may be logged only 1 time on each band.

9. Multipliers: Each different ITU zone worked on each band gives 1 point for multiplier. In addition, 1 point for a multiplier on each band by each mode is given by special stations operating from memorable places and objects of the Russian space industry according to the list below.

SWL have no multipliers.

The list of special stations can be expanded. The organizers invite you to participate in the subgroup Special Stations from the Russian Federation and other countries working from places related to the exploration of world space.

10. Final score: The total number of QSO points on all bands times the total number of multipliers worked on all bands.

11. Awards: Big cups are awarded to participants who take first place in the world in groups B, C, E, B-SAT, C-SAT, Special.

Small cups are awarded to participants who take first places in the world in groups B1-SSB, B1-CW, B1-MIX, B2, C1, E1-SSB, E1-CW, E1-MIX, E2.

Medals are awarded to participants who take first places (separately for stations located in the European part of the Russian Federation, the Asian part of the Russian Federation and for foreign stations) in groups A, D, G-SAT.
