Le bandplanning entre 1.810 et 2.000 MHz

1.8 MHz Band

1810 - 1838 200 CW, 1836 kHz - QRP Centre of Activity
1838 - 1840 500 Narrow band modes
1840 - 1843 2700 All modes – digimodes, (*)
1843 - 2000 2700 All modes, (*)

Radio Amateurs in countries that have a SSB allocation ONLY below 1840 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 Bandplan. (Davos 2005)


All modes CW, SSB and those modes listed as Centres of Activity, plus AM (Consideration should be given to adjacent channel users).
Image modes Any analogue or digital image modes within the appropriate bandwidth, for example SSTV and FAX.

Narrow band modes All modes using up to 500 Hz bandwidth, including CW, RTTY, PSK etc.

Digimodes Any digital mode used within the appropriate bandwidth, for example RTTY, PSK, MT63 etc.

(*) Lowest dial setting for LSB Voice mode: 1843, 3603 and 7053 kHz.


Amplitude modulation (AM) may be used in the telephony sub-bands providing consideration is given to adjacent channel users. (NRRL Davos 05).

CW QSOs are accepted across all bands, except within beacon segments. (Recommendation DV05_C4_Rec_13).

Contest activity shall not take place on the 10, 18 and 24 MHz bands.

Non-contesting radio amateurs are recommended to use the contest-free HF bands (30, 17 and 12m) during the largest international contests. (DV05_C4_Rev_07).

The term “automatically controlled data stations” includes Store and Forward stations.

The frequencies in the bandplan are understood as “transmitted frequencies” (not those of the suppressed carrier!).

Unmanned transmitting stations:

IARU member societies are requested to limit this activity on the HF bands. It is recommended that any unmanned transmitting stations on HF shall only be activated under operator control except for beacons agreed with the IARU Region 1 beacon coordinator, or specially licensed experimental stations.

Sideband Usage Below 10MHz use lower sideband (LSB), above 10 MHz use upper sideband (USB).
