IARU R1 145 MHz CONTEST

RULES

The main objectives are to make as many contacts as possible and to have fun. Other objectives may include improving your operating skills, testing new equipment configurations and techniques,
expanding your horizons by operating on the microwave bands and exploring radio propagation.
Definitions
• Station: set of antennas, transmitters and receivers used during the contest on each frequency band (i.e. multiband setups are composed of multiple stations).
• Location: geographical area with diameter of no more than 500 meters where the station resides during the contest.
• Call Sign: identification of the station during the contest. Added prefix and/or suffix do not generate different call sign (i.e. S50AAA/p or DL/S50AAA are the same call sign as S50AAA).
• Operator: an individual that operates the station during the contest using the station’s call sign.
Operator may reside inside (local operator) or outside (remote operator) the location. During the contest an operator may operate only stations that form one entry.
• Entries:
o MULTI operator: stations from the same location, operated by more than one operator and using one callsign on all bands.
o SINGLE operator: stations from the same location, operated by the same operator and using one callsign on all bands, with no operational assistance of another person during
the contest.
o 6 HOURS: stations from the same location, operated by any number of operators and operating according to the 6 hours’ time rule. The 6 hour time segment can be divided into maximum two periods. The time of the first QSO sets the start time of the first
period. When operating in two periods, the pause between the periods must be longer than 2 hours. The first time difference of 2 hours or more between two consecutive QSOs marks the pause segment. Only the QSOs that fall into the combined 6 hour time
segment will be counted for points. Participants are welcome to operate longer than 6 hours and in such case they shall send their complete log (the contest robot will automatically extract the 6 hours part from the log, while the rest of the log entries will
be used for cross-checking purposes).
o LOW POWER: multi or single operator entries, transmitting with total of up to 100 W PEP from the transmitter and using only one directional or omnidirectional antenna system.
The same antenna must be used for transmit and receive. Directional antenna system is a single directional antenna or a group (array) of single directional antennas, grouped together to achieve maximum obtainable gain in a given direction (that is, all the
antennas in the group shall be pointed in the same direction). Omnidirectional antenna is an antenna with a radiation pattern that has approximately the same gain in all azimuth directions.
Conditions for entrants
All licensed radio amateurs in Region 1 may participate in the contest.
The entrants must operate within the letter and spirit of the contest. Entrants must operate according to the license conditions of the country where the station resides. Stations operating
under special high power license can only entry as check logs.
Date of contests
• The 145 MHz contest will start on the first Saturday of September.
• The contest will commence at 1400 hours UTC on the Saturday and end at 1400 hours UTC on the Sunday.
