N ote 3 — Broadband segments may be used for any combination of high-speed data e. Wide detection bandwidth, slow sweep rates, and commonly high local ambient noise levels generally mask weaker emissions.

Consideration should be given to adjacent channel users. FM, d i gi tal. Segment 29 — 29 kHz changed from maximum bandwidth of 2 Hz to maximum 6 Hz. Narrow bandwidth mode segment with maximum bandwidth of Hz extended by 10 kHz now from 10 kHz to 10 kHz.

USB is limited to 2. Effective 17 August Unmanned transmitting stations, and operation involving unmanned transmitting stations, must adhere to the frequency and bandwidth limits of the band plan.

IBP, worldwide time shared beacons. IBP, regional time shared beacons.

To prevent any out of band transmission the maximum dial setting for USB Voice mode should be 3 kHz below upper band edge on bands 20 m to 10 m. Any measurement of out-of-band emissions should be made using a receiver bandwidth significantly narrower than the transmitter bandwidth.

All modes, SSB contest preferred, priority for intercontinental operation. S Amateurs with perfect transmitters, the highest usable frequency in the 80m band for lower side band phone is 3. Please help improve it or discuss these issues on bzndplan talk page. Functi o nal Use.


As a result, authorities in the affected parts of the world restrict amateur allocations between 3. This article may require cleanup to meet Wikipedia’s quality standards.

HF – International Amateur Radio Union – Region 1

During contests bandpaln band is filled with activity beginning before sunset and continuing all through the night. February Learn how and when to remove this template message. Number of Bandplab Repeater channels increased to eight, former FM simplex channels became new baandplan input, respectively repeater output channels. Broadband segment may be used for any combination of high-speed data eg: Highest dial setting for USB Voice mode on the 60 m band: Most amateurs interested in regional communication use low, wire antennas, such as horizontal dipolesinverted vee dipole antennas or loop antennas on this band.

Amateur radio frequency allocations. Secure Site Login Forgot Password? Narrow band modes – digimodes automatically controlled data stations unattended. Contests should be restricted to80, 40, 20, 15 and 10 m. Effective 1 January Amateurs wishing to operate on either 2, or meters must first register with the Utilities Technology Council online at https: However, amateurs outside the Americas must share this useful piece of spectrum with other users, usually on a joint primary basis.

That is 60, 30, 17, and 12 m bands bandllan not be used for contests. All modes — digimodes, automatically controlled data stations unattended.

A recommendation for all radio amateurs how to use the bands, as revised at the Interim Meeting Viennaeffective 01 June Radio Amateurs in countries that have bndplan 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.


The 80 meter or 3.

Back to Top Having Trouble? Several modifications to be ratified by General Conference QST Get it here. The band segment 10 kHz to 10 kHz may be used for SSB transmissions in the area of Africa south of the equator during local daylight hours.

All modes — beacons. Davos 80 m Band: While some people reporting out-of-band operation might use a wide receiver bandwidth, receiver bandwidth adds to transmitter bandwidth, so the perception is bandwidth is wider than the true bandwidth. Narrow band modes, digimodes. E mi s sion Bandwidth. Segment bandplsn — 29 kHz: Effective 01 June All modes – digimodes.

80-meter band

During spring and summer year-round in the tropicslightning from distant storms creates significantly higher background noise levels, often becoming an insurmountable obstacle to maintaining normal communications. Radio spectrumElectromagnetic spectrum. Narrow band modes, digimodes segment moved and extended from 7 — 7 kHz to 7 -7 kHz.

Band Plan Band Plan A band plan refers to a voluntary division of a band to avoid interference between incompatible bandplsn.

Amateur use of these frequencies should be first coordinated with the National Science Foundation esm nsf. Most operations of this type are from fishing vessels. All modes, USB recommended for voice operation.
