PREFERRED MODE
AND USAGE

  135.7 – 137.8 200  CW, QRSS and narrow band digital modes

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 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)

1.8 MHz Band: 1810 - 1838 200 CW, 1836 kHz  - QRP Centre of Activity

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)

3.5 MHz Band: 3500 - 3510 200 CW, priority for intercontinental operation

3735 kHz - Image Centre of Activity                    
3760 kHz - Region 1  Emergency Centre of Activity
3775 - 3800 2700 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.

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.

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)
