General Rules for ARRL Contests Above 50 MHz

1. General Rules for all ARRL Contest Above 50 MHz:

1.1. See General Rules for All ARRL Contests.

1.2. Individuals and stations are limited to one entry per contest.

1.3. A transmitter, receiver, or antenna used to contact one or more stations may not subsequently be used under any other call during the contest period, except as provided for in General Rules for All ARRL Contests number 3.5.

1.4. Stations may be worked for credit only once per band from any given grid square, regardless of mode. This does not prohibit working a station from more than one grid square with the same call sign (such as a Rover).

1.5. Crossband QSOs do not count.

1.6. Aeronautical mobile contacts do not count.

1.7. Retransmitting either or both stations, or use of repeater frequencies, is not permitted.

1.7.1. This prohibits use of all repeater frequencies.

1.7.2. Contest entrants may not transmit on repeaters or repeater frequencies for the purpose of soliciting contacts.

1.8. Use of the national simplex frequency, 146.52 MHz, or immediately adjacent guard frequencies, is prohibited.

1.8.1. Contest entrants may not transmit on 146.52 for the purpose of making or soliciting QSOs.

1.8.2. The intent of this rule is to protect the national simplex frequency from contest monopolization.

1.8.3. There are no restrictions on the use of 52.525, 223.50 or 446.000 MHz.
Participants are, however, encouraged to not monopolize the calling frequencies throughout the contest period.

1.9. Only recognized FM simplex frequencies may be used, such as 144.90 to 145.00; 146.49, .55 and .58, and 147.42, .45, .48, .51, .54 and .57 MHz on the 2-meter band.

1.9.1. Local-option simplex channels and frequencies adjacent to the above that do not violate the intent of the above rules, or the spirit and intent of the band plans as recommended in the ARRL Repeater Directory, may be used for contest purposes.

1.10. While no minimum distance is specified for contacts, equipment should be capable of communications at a range of at least 1 km.

1.11. A station located precisely on a dividing line between grid squares must select only one as the location for exchange purposes. A different grid-square multiplier cannot be given without moving the complete station (including antennas) at least 100 meters.

1.12. Above 300 GHz, contacts are permitted for contest credit only between licensed amateurs using mono-chromatic signal sources (for example, laser and LED) and employing at least one stage of electronic detection on receive.  Laser usage is restricted to ANSI Z136 Class I, II, IIa, and IIIa (i.e.; output power is less than 5 mW).

1.13. Marine Mobile (and Maritime) entries will be listed separately as "Marine Mobile" in the listings and compete separately for awards.

1.14. Participants are reminded that the segment 50.100-50.125 MHz should be used for intercontinental QSOs only, using 50.125 MHz as a calling frequency, then QSY after contact is established.

1.15. The total transmitter output power for any high power entry in any category for an ARRL Contest is either 1500 Watts PEP or the maximum allowable power level established by the national licensing authority of your country, whichever is lower.

2. Entry Categories: The following categories are defined for ARRL contests on bands above 50 MHz. See the rules for each contest to determine which categories apply and whether additional categories exist for that contest. Transmit power level is measured at the output of the final stage of amplification.

2.1. Single Operator: One person performs all transmitting, receiving, spotting, and logging functions as well as equipment and antenna adjustments. Only one transmitted signal is permitted at any given time. Use of spotting assistance or nets (operating arrangements involving other individuals, DX-alerting nets, internet chat rooms, packet, etc) is not permitted.

2.1.1. Single Operator Low Power:

2.1.1.1. Power limits on any band may not exceed the following:

2.1.1.1.1. 50 MHz and 144 MHz--200 W PEP.

2.1.1.1.2. 222 MHz and 432 MHz--100 W PEP.

2.1.1.1.3. 902 MHz and above--50 W PEP.

2.1.2. Single Operator High Power: Power limits on any band exceeds the limits for the Single Operator Low power.

2.1.3. Both Single Operator High and Low Power stations compete for all-band and single-band awards.

2.1.4. Overall and single-band winners are recognized both in QST score listings and in awards offered.

2.2. Single Operator Portable:

2.2.1. Ten (10) W PEP output or less.

2.2.2. Portable power source.

2.2.3. Portable equipment and antennas.

2.2.4. Single Operator Portable stations must operate from a location other than a permanent station location.

2.2.5. Single Operator Portable stations may not change locations during the contest period outside of the original 500-meter diameter permitted circle.

2.3. Single Operator, 3-Band: (not available for the August UHF Contest)

2.3.1. Restricted to 50, 144 and 432 MHz.

2.3.2. Power limits are 100 W PEP on 50 and 144 MHz, 50 W PEP on 432 MHz.

2.4. Single Operator, FM Only (not available for the August UHF Contest)

            2.3.1. All QSOs must be made using Frequency Modulation (FM).

            2.3.2. Restricted to 50, 144, 222 and 440 MHz.

            2.3. Power limits are 100 W on all bands.

2.5. Rover: A rover is comprised of no more than two operators that moves among two or more grid squares during the course of a contest. An operator may perform any or all rover functions, but a driver's function shall be limited to driving the vehicle. Drivers may be switched out during the event. Any number of observers is also allowed, however observers may not perform any rover function at any time. Rover vehicles with only one occupant are allowed to perform all functions listed above.

2.5.1. A rover vehicle may transport only one station using a single call sign. An exception is provided for in "General Rules for All ARRL Contests" number 3.5 (Family Rule).

2.5.2. A rover may not operate with more than one call sign.

2.5.3. Rover vehicles must transport all the equipment, power supplies, and antennas used at each operating site.

2.5.4. Rovers MUST sign "rover" on Phone and /R on CW and digital modes after their call sign.

2.5.5. All Rovers are encouraged to adopt operating practices that allow as many stations as possible to contact them.

2.5.6. Rover operators may submit separate logs for single operator (fixed station) in addition to their rover entries. Rovers submitting a score for inclusion in a club competition must also include a secondary summary sheet indicating the portion of the score that counts for the club score if any of the QSOs submitted take place outside of their club's territory.

2.5.7. Rovers are permitted to use APRS. Rovers using APRS transmit only their call sign and position. Any multi-op station may access rover APRS data directly or via the Internet.

2.5.8. A rover may not make more than 100 QSOs with any other one rover.

2.6. Limited Rover. Same as the "Rover" class above, but competes using only the lowest four bands available for any given contest (6M - 432 MHz for VHF+ contests, 222MHz - 1.2 GHz for August UHF). Output power limits shall be the same as those defined for the Single Operator Low Power category (2.1.1)

2.7. Unlimited Rover. Same as “Rover” class above, but Unlimited Rovers may use more than two operators and are exempt from rules 2.5.3 and 2.5.8.

2.7.1. Unlimited Rover scores may NOT be applied to a club score for Club Competition.

2.8. Multioperator (includes Single Operator stations that use spotting assistance:

2.8.1. Multioperator (Unlimited): Stations submit logs with more than four bands used.

2.8.2. Limited Multioperator: Stations submit logs with a maximum of four bands used. (Logs from additional bands used, if any, should be included as checklogs.)
