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 QSO 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 QSO and HF QSO 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.
It is prohibited to use robotic software and hardware (bots, RPA, AI/ML-algorithms, etc.) for receiving test messages, transferring a call and control messages, logging contacts made without the participation of an operator.
Self-spotting is allowed:
– when changing the band;
– no more than once every 15 minutes.
7. Exchange: RST and ITU zone number. Special stations (see the list below) transmit a two-letter combination instead of the ITU-zone number.
8. QSO points:
- 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 3.5 MHz 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.
