IARU REGION 1 HF BAND PLAN
?as revised at Interim Meeting Vienna 2016, effective 1 June 2016
Defined at WRC conferences, IARU assigned bands plans to each Region under the supervision of ITU.
There are slight difference between European/Russia/Middle East (IARU Region 1), American (IARU Region 2), Asian and Oceanian bands plans.
According your national regulation, you are usually not allow to listen outside the ham bands and broadcasts. Listen to Maritime, Army or Red cross frequencies for example are prohibited, excepting if you are authorized by these institutions to listen or use these frequencies. In the same way you can use a scanner but only to listen to hams bands and broadcasts. You are not allowed to save in memory or to transfert to the VFO frequencies dedicated to other services. Abuses are punished by law.
BandFrequency (kHz)Max Bandwidth (Hz)?? Preferred mode and usage
-000 - 150VLF band. Signals on these frequencies cannot propagate well via the ionosphere, but are able to penetrate ocean water well. As a result, several military stations used for submarine communications are found here.
Most transmissions are in CW and RTTY.
2200m Band135.7 – 137.8200LF band. This band is assigned primarily to fixed services and maritime mobile
Secundary fixed amateur service with a 1W PEP max.on a secondary basis by the Amateur Service in CEPT countries.
In IARU Region 1 amateur assignation to CW, QRSS and narrow band digital modes as next :
135.7-136.0 : station tests & transatlantic reception windows
135.90-135.98 : preferred transatlantic window for Europe to North America transmissions of very slow CW (QRSS)
135.89-136.05 : preferred transatlantic window for Europe-North America contacts
136.0-137.1 : CW
1371.-137.6 : non-CW modes (Hell, Wolf, PSK, etc)
137.6-137.8 : very slow CW (QRSS) centred on 137.7
137.7-137.8 : preferred transatlantic window for Europe to North America transmission
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)
2000m Band150 - 540It is what most SWLs mean by longwave. Most stations heard in this range are navigation beacons that continuously repeat their call signs in Morse code. There is also a broadcasting band in Europe from 155 - 281 kHz.
Some RTTY signals are found in the upper end of this band. Marine weather and safety broadcasts, known as NAVTEX, are transmitted on 512 kHz.
Your best reception here will be at night, especially during the fall and winter months.
630m Band472 - 475200WRC-2012 decided to allocate 472-479 to the amateur service on a secondary basis. So far the following administrations have allocated this band to the amateur service:
Denmark: Effective 1 January 2013.
Germany: The German administration (BNetzA) informed in an official gazette, that effective 13 June 2012 German radio amateurs with licence class A may use the band 472-479 kHz (in anticipation of the normally needed changes in the National Frequency Allocation Table). Power limit is 1 watt e.r.p , max. bandwidth 800 Hz.
Monaco: The "Direction des Communications Electroniques" of the Principality of Monaco, by official letter of May 18th 2012, has allocated the segment 472 - 479 kHz, to the amateur service with secondary status, with a maximum power of 1 (one) Watt e.i.r.p.
Netherlands: Effective 1 January 2013 with 100 Watts PEP
475 - 479Same as above + digimodes
If a frequency is to be selected, particular attention must be paid to still exsiting Non Directional beacons (NDB) of the radio navigation service.
Although the maximum bandwidth is not specified, 500 Hz is suggested.
600m Band501 - 504In Belgium is allocated on a secondary basis CW only (all speeds, so including QRSS). Power limitation is 5 Watt ERP.
170m Band1700 - 1800This is a grab bag of miscellaneous radio communications, mainly beacons and navigation aids. You may hear several transmitters that sound like chirping cricket
160m BandMF band. This is the 160-meter amateur radio band. Fixed primary service. Most voice communications will be in LSB, with best reception at night during the fall and winter months.
1810 - 1838200CW, 1836 kHz ? - QRP Centre of Activity
1838 - 1840500Narrow band modes
1840 - 18432700All modes – digimodes, (*)
1843 - 20002700All modes (*)
In IARU Region 1 amateur assignation is next:
1810-1838: CW
1838-1840: digimode except packet, CW
1840-1842: digimode except packet, phone, CW
1838-2000: phone,CW.
In IARU Region 2 Canada, the segment 1800-2000 is dedicated to CW, RTTY, data, test, phone and image
In USA, for General, Advanced and Extra licensed, 1800-2000 is dedicated to CW, RTTY and digimode (< 2.7 kHz), no SSB.
In IARU Regions 2 and 3, the segment 1800-1840 is dedicated to CW.
In Belgium the segment extents from 1810-1875, and is dedicated to QRP with 10W PEP only over 1.850 MHz (Secundary).
In LX the segment extents from 1810-1850, and in QRP with 10W PEP between 1810-1830. Primary over 1.830 MHz
In IARU Region 2, QRP/DX extents from 1830-1850
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).
This band is the only medium-frequency (MF) allocation to the amateur service. Its propagation characteristics allow short-range communications during daytime hours and medium and long-range communications during night-time hours. This band is particularly useful during sunspot minima, when the maximum usable frequency (MUF) is below 3500 kHz.
An increasing number of countries in Region 1 are authorising amateur operation above 1850 kHz on a low-power, not-to-interfere basis. There is reason to believe that the growing use of GNSS (GPS and GLONASS) positioning systems will render obsolete radiolocation systems operating in the band 1900–2000 kHz.
2000 - 2300This range is used maritime communications (fishery), with 2182 kHz reserved for distress messages and calling. There are also several regularly scheduled maritime weather broadcasts by U.S.Coast Guard stations. Most activity will be in USB, and best reception at night.

2498 - 2850More maritime stations (fishery) are found here, as well as standard time and frequency stations WWV and WWVH on 2500 kHz.
2850 - 3150This band is used mainly by aeronautical stations in USB. Several stations broadcasting aeronautical weather bulletins, and you can also hear traffic between airports and airplanes aloft.
3150 - 3200This range is allocated - fixed stations, with most communications in RTTY.
90m Band3200 - 3400This is a very interesting segment. This us the 90-meter broadcasting band, used mainly by stations in the tropics. Canadian standard time and frequency station CHU can be heard on 3330 kHz. Several fixed stations also use this range, including several associated with various agencies of the U.S. Government. Gendarmerie Traffic stations (France). Best reception will be at night.
3400 - 3500This range is used for aeronautical communications in USB.
80m BandMF band. This is the 80-meter amateur radio band. Fixed primary service. Officiously the segment above 3790 is usually choosen for DXing in respect with the bandplan. Best reception is at night.

In IARU Region 2, in Canada, the segment 3500-4000 can be used for CW, RTTY, data, test, phone and image.
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.

5005 - 5351.560-m band. The National Telecommunication and Information Administration (NTIA) is the primary user of this band.
It is strongly recommended that fresquencies within the WRC-15 allocation only be used if there are no other frequencies available at 5 MHz under domestic (ITU-R article 4.4) permissions.
Local nets and long rag chew QSOs should not use the WRC-15 allocation at 5 MHz but should instead make use of the 80-meter, 60-meter or 40-meter bands where there is more spectrum available.
This range is a real jumble! Several broadcasting stations are found in the lower part of the segment, and fixed and mobile stations in SSB, RTTY, and CW are found throughout this band. Best reception is during the evening and night hours.
This band is channelized. Used by amateur radios service in United Kingdom, Norway and Denmark only.
