4.0.1 Preferred mode and usage Notes

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.
Sideband Usage Below 10MHz use lower sideband (LSB), above 10 MHz use
  upper sideband (USB)
(*) Lowest dial setting for LSB Voice mode: 1843, 3603 and 7043 kHz
   

4.0.2 Notes

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 DV05C4Rec13)

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. (DV05C4Rev07)

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

Transmitting frequencies:

The announced 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.

1.8 MHz band:

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. (UBA - Davos 2005)

3.5 MHz band:

Intercontinental operations should be given priority in the segments 3500-3510 kHz and 3775-3800 kHz. Where no DX traffic is involved, the contest segments should not include 3500-3510 kHz or 3775-3800 kHz. Member societies will be permitted to set other (lower) limits for national contests (within these limits). 3510-3600 kHz may be used for unmanned ARDF beacons (CW A1A) (Recommendation DV05C4Rec12) Member societies should approach their national telecommunication authorities and ask them not to allocate frequencies to other than amateur stations in the band segment that IARU has assigned to intercontinental long distance traffic.

7 MHz band:

The band segment 7035-7045 kHz may be used for automatically controlled data stations (unattended) traffic in the area of Africa south from the equator during local daylight hours.

10 MHz band:

SSB may be used during emergencies involving the immediate safety of life and property and only by stations actually involved in the handling of emergency traffic. The band segment 10120 kHz to 10140 kHz may be used for SSB transmissions in the area of Africa south of the equator during local daylight hours. News bulletins on any mode should not be transmitted on the 10 MHz band.

28 MHz band:

Member societies should advise operators not to transmit on frequencies between 29.3 and 29.51 MHz to avoid interference to amateur satellite downlinks.

Experimentation with NBFM Packet Radio on 29 MHz band:

Preferred operating frequencies on each 10 kHz from 29.210 to 29.290 MHz included should be used. A deviation of ±2.5 kHz being used with 2.5 kHz as maximum modulation frequency.
