*1/12/2015* Rule 2.5 updated to clarify spotting assistance allowed for Single Operator, Unlimted Categories.
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.
