RR 5.67A Stations in the amateur service using frequencies in the band 135.7-137.8 kHz shall not exceed a maximum radiated power of 1 W (e.i.r.p.) and shall not cause harmful interference to stations of the radio navigation 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 authorizing such use.

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 license administrations to adjust the phone allocations in accordance with the Region 1 Bandplan.

All modes, priority for intercontinental operation

 

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 ) (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.

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.

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

 

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.
