Band Plans

8e.1 Recall that band plans are produced by the IARU.

Recall that the band plans state that:

• no SSB operation should take place in the 10MHz 30m band

• no contests should be organised in the 10MHz (30m), 18Mhz (17m) and 24MHz (12m) bands

• narrow band modes are at the lower end of most bands

• lower sideband operation normally occurs below 10 MHz and upper sideband above 10MHz

• transmission on beacon frequencies must be avoided.

• transmission on satellite frequencies should be avoided for terrestrial contacts.

Questions on beacon and satellite frequencies will be limited to the 14Mhz (20m) and 144MHz (2m) bands and copy of the Band Plans will be provided.

Whilst some band plans are included in the documentation for the exam for the 14Mhz (20m) and 144MHz (2m) bands you need to be to know that the other band plans state that:

• no s.s.b. operation should take place in the 30m band

• no contests should be organised in the 12, 17 and 30m bands (WARC bands WARC = World Administrative Radio Conference)

• narrow band modes are at the lower end of most bands

• lower sideband operation normally occurs below 10 MHz and upper sideband above 10MHz

• transmission on beacon frequencies must be avoided.

• transmission on satellite frequencies should be avoided for terrestrial contacts.

It is also a good idea to be aware of the beacon and satellite frequencies on these two bands.
