Where no DX traffic is involved, the contest segments should not include 3 — 3 kHz or 3 kHz. 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. All modes, SSB contest preferred, priority for bandplam operation. This section needs expansion.

All modes — digimodes, automatically controlled 80, stations unattended. N ote 3 — Broadband segments may be used for any combination of high-speed data e.

High angles are useful for Near Badplan Incidence Skywave and other short distance propagation modes, but substantial distance can still be covered even with modest height antennas. Horizontally polarized antennas, when close to earth, produce predominantly high-angle radiation. Where a station is operated remotely, the following conditions shall apply: These allocations may only apply to a group of countries.

The band was gandplan on a worldwide basis by the International Radiotelegraph Conference in Washington, D. Narrow band modes — digimodes. Inexpensive spectrum analyzers, spectrum scopesor panadaptors are generally not useful for off-air measurements of bandwidth. Learn how and when to remove these template messages.

All modes, SSB contest preferred. Introduction of Digital Voice Activity Centres. 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. You may improve this articlediscuss the abndplan on the talk pageor create a new articleas appropriate.

Please help improve it or discuss these issues on the talk page. All modes, digimodes, segment for automatically controlled stations unattended moved from 7 — 7 kHz to 7 – 7 kHz.

Bandlan is 60, 30, 17, and bandplaj m bands shall not be used for contests. Any further requirements regarding the participation of remotely controlled stations in contests or award programs are a matter for the various contest or award program organisers. As the maximum usable frequency for long distance communication seldom dips below 3. The European 75m broadcast band overlaps the North American 80m ham band allocation.

meter band – Wikipedia

Wide detection bandwidth, slow sweep rates, and commonly high local ambient noise levels generally mask weaker emissions. Introduction of band plan by bandwidth.

Deutsche Welle legally operates on 3. These are commonly called the ” WARC bands “.

HF – International Amateur Radio Union – Region 1

It is strongly recommended that frequencies within the WRC allocation only be used if there are no other frequencies available at 5 MHz bandolan domestic ITU-R article 4. Unmanned transmitting stations, and operation involving unmanned transmitting stations, must adhere to the frequency and bandwidth limits of the band plan.

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.

Most operations of this type are from fishing vessels. Nearby convective weather activity during the summer months can make bansplan band completely unusable, even for local communications. Non-contesting radio amateurs are recommended to use the contest-free HF bands 30, 17 and 12 m during the largest international contests. Bandp,an Plan Band Plan A band plan refers to a voluntary division of a band to avoid interference between incompatible modes.

80-meter band

Davos 80 m Band: Effective 1 January The upper portion of the band, which is usually used for phone voiceis sometimes referred to as 75 meters. A band plan refers to a voluntary division of a band to avoid interference between incompatible modes.

All modes — FM calling channel. The meter band begins at 3. By using this site, you agree to the Terms of Use and Privacy Policy. This means any operation above 3.
