Wavebands

The following table gives a list of all the bands authorized in the world.

The indicated limits correspond to the maximum noted; very often, local legislations of countries impose more restricted limits.

 

Name Lower limit Upper limit Notes

2 km 135,7 kHz 137,8 kHz Band limited to the numerical modes (Morse included) with 1 W PIRE, authorized since the 2007 CAMR.
600-meter band 501 kHz 504 kHz Used only in Germany, Belgium, Canada, Denmark, the United States, Ireland, Iceland, Norway, Netherlands, Czech Republic, the United Kingdom, Sweden. The upper limit of the band is variable according to the countries.
160-meter band 1 800 kHz 2 000 kHz Upper band limit variable according to the countries
80-meter band 3 500 kHz 4 000 kHz Band shared with other services, limits variable according to the countries.
60-meter band 5 200 kHz 5 405 kHz Used only in the United States, in the United Kingdom, in Norway, in Finland and Iceland with channels inside the band.
40-meter band 7 000 kHz 7 300 kHz Upper band limit variable according to the countries. The radio hams have a secondary statute until 2009, date on which the range from 7100 Khz to 7200 Khz will be completely allotted to them.
30-meter band 10 100 kHz 10 150 kHz
20-meter band 14 000 kHz 14 350 kHz
17-meter band 18 068 kHz 18 168 kHz

10-meter band 28 000 kHz 29 700 kHz
 
 
VHF/UHF bands
6-meter band 50,000 MHz 54,000 MHz Variable limits and restrictions according to the countries
4-meter band 70,000 MHz 70,500 MHz In certain countries only
2-meter band 144,000 MHz 148,000 MHz Limited to 146 MHz in area 1.
1,25 m 219,000 MHz 225,000 MHz Only in area 2.
70 cm 420,000 MHz 450,000 MHz Restricted from 430 MHz to 440 MHz in area 1 and from 430 MHz to 450 MHz in area 2. On frequency 433 MHz the radio hams have priority and have notable powers of emission so that the domestic facilities without licence and of very small powers are likely to be disturbed.
33 cm 902,000 MHz 928,000 MHz Only in area 2.
23 cm 1 240,000 MHz 1 325,000 MHz Upper band limit variable according to the countries
13 cm 2 300,000 MHz 2 450,000 MHz Variable limits according to the countries. On the frequency 2400 MHz the radio hams have priority and have notable powers of emission so that the domestic facilities Wi-Fi without licence and of very small powers are likely to be disturbed.
