SPECIAL Stations operating from places of memory related to space exploration and Russian space industry.
6. During the contest:
Participants of groups B, B2, C, E are allowed to conduct QSO via amateur radio satellites. These QSO sare counted as QSO conducted on a single additional band. Conducting a QSO via geostationary satellites is counted only in the B-SAT-GS 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-SAT, E-SAT can also make QSO for 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.
Stations of “SPECIAL” category can use any number of transmitters, but only one signal can be present on each band at the same time.
Category C must remain on the same HF band for at least 5 minutes after the first QSO on this band has been made.
Duplicates are counted on different bands and different modes. When working via satellites (not geostationary), QSO with different modes and on different orbits are counted.
That is, on each satellite orbit with the same correspondent, a CW QSO and an SSB QSO are counted.
When working via geostationary satellites, QSO in different modes (CW and SSB) are counted.
It is allowed to use FM mode for contacts with hams operating from the International Space Station ( RS0ISS).
Self-spotting is allowed.
- Exchange:
RST and ITU zone number. Special stations (see the list below) transmit a two-letter combination instead of the ITU-zone number. - QSO points:
A QSO within the same country (P-150-C) counts as 2 points.
A QSO with a different (P-150-C) country on the same continent counts as 3 points.
A QSO with a different continent counts as 4 points.
A satellite QSO counts as 50 points.
Contacts with RS0ISS count as 100 points.
QSO points on:
1.8 MHz and 3.5 MHz are multiplied by 3;
7 MHz are multiplied by 2;
14, 21 and 28 MHz are multiplied by 1.
Phone 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.
- Multiplers:
Each different ITU zone worked on each band counts as 1 point for multiplier. In addition, QSOs with special stations according to the list below count as 1 point for multiplier on each band and in each mode.
SWL have no multipliers.
