On 80 meters, nearly all areas of the world are subject to local weather induced noises from thunderstorms. Effective 29 March The 80 meter or 3. All modes — FM calling channel.

The examples and perspective in this article deal primarily with the United States and do not represent a worldwide view of the subject. Several modifications to be ratified by General Conference Functi o nal Use. CW contest preferred segment 7 — 7 kHz withdrawn. Non-contesting radio amateurs are recommended to use the contest-free HF bamdplan 30, 17 and 12 m during the largest international contests. All modes, digimodes, segment for automatically controlled stations unattended moved from 7 — 7 kHz to bandpln – 7 80n.

This is particularly important in the 30 meter band where the amateur service only has secondary status.

meter band – Wikipedia

High angles are useful for Near Vertical Incidence Skywave and other short distance propagation modes, but substantial distance can still be covered even with modest height antennas. This handplan may require cleanup to meet Wikipedia’s quality standards. Number of FM Repeater channels increased to eight, former FM simplex channels became new repeater input, respectively repeater output channels. Note 1 — Includes all other emission modes authorized in the 9 cm amateur band whose necessary bandwidth does not exceed the suggested bandwidths listed.

International amateur radio frequency allocations.

Broadband segment may be used for any combination of high-speed data eg: News bulletins on any mode should not be transmitted on the 10 MHz band. CW, Narrow band modes — digimodes.

All modes — beacons. Any measurement of out-of-band emissions should be made using a receiver bandwidth significantly narrower than the transmitter bandwidth.

IBP, exclusively for beacons. You can help by adding to it. Using other phone modes such as upper side band, amplitude or frequency modulation with 3. E mi s sion Bandwidth.

This means any operation above 3. Inexpensive spectrum analyzers, spectrum scopesor panadaptors are generally not useful for off-air measurements of bandwidth. Amateur radio operators may transmit messages via unmanned transmitting stations during coordinated emergency, and disaster preparedness exercises, limited to the duration of such exercises, using a bandwidth not exceeding 2 Hz.

Effective 26 September This applies irrespective of the location of the operator. Introduction of new segment 29 — 29 kHz for FM simplex operation 10 kHz channels.

Contact us Add to favorites Set as homepage. Remote controlled operation on HF. IBP, worldwide time shared beacons. Introduction of band plan by bandwidth.

It is strongly recommended that frequencies within the WRC allocation only be used if there are no other frequencies available at 5 MHz under domestic ITU-R article 4. These allocations may only apply to a group of countries.

CW, priority for intercontinental operation. Radio Amateurs in countries that have a SSB allocation ONLY below kHz, may continue to use it, but the National Societies in those countries are requested to take all necessary steps with their licence administrations to adjust the phone allocations in accordance with the Region 1 Band plan.

80-meter band

Unmanned transmitting stations, and operation involving unmanned transmitting stations, must adhere to the frequency and bandwidth limits of the band plan. Narrow band modes, digimodes. Such communication should be announced regularly on the frequency, and radio amateurs not participating in the communication should cooperate by not transmitting on the frequency.
