RR 5.67A Stations in the amateur service using frequencies in the band 135.7-137.8 kHz shall not exceed a maximum radiatedpower of 1 W (e.i.r.p.) and shall not cause harmful interference to stations of the radionavigation service operating in countries listed in No. 5.67. (WRC-07) (Cavtat 2008)

RR 5.67B The use of the band 135.7-137.8 kHz in Algeria, Egypt, Iran (Islamic Republic of), Iraq, Libyan Arab Jamahiriya, Lebanon, Syrian Arab Republic, Sudan and Tunisia is limited to the fixed and maritime mobile services. The amateur service shall not be used in the above-mentioned countries in the band 135.7-137.8 kHz, and this should be taken into account by the countries authorising such use. (WRC-07)(Cavtat 2008)

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 totake all necessary steps with their licence administrations to adjust the phone allocations in accordance with the Region 1 Bandplan. (Davos 2005)

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 ) (Davos 2005)
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.

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