20-meter band frequencies
This is my interpretation of the 20-meter band frequencies. I thought this would be of interest to readers. Other than the military, amateur radio operators are the only users of the radio spectrum that are permitted to change frequency. This means that as licensed amateur radio operators, we do not have to restrict ourselves to stipulated channels. Having said that, the 20-meter band covers a wide range of frequencies and many applications for amateur radio in the band involve automated equipment such as repeaters, satellites, and beacons. For these reasons it has become general practice to specify frequencies as if they were channels.
20-meter band frequencies
Specifying band frequencies does not distract from the enjoyment of working on the 20-meter band. It basically means that you will now know where to listen for other users. It also means that when you transmit, you are less likely to interfere with other users that cannot change frequency, such as repeaters, satellites, and beacons. Here is my interpretation of the 20-meter band frequencies.
|14.000||Start of band|
|14.000-14.060||Telegraphy - contest preferred||14,040 kHz Islands On The Air IOTA CW
14,055 kHz QRS (slow telegraphy) Centre of Activity.
14,058 kHz and down frequency FISTS CW Club centre of activity.
|14,060-14,070||Telephony||14,060 kHz QRP CW centre of activity.|
|14,070-14,089||Narrow band modes||14,0956 kHz dial freq
14,0970-14,0972 kHz transmit freq
|14,089-14,099||Narrow band modes||automatically controlled data stations (unattended)|
|14,099-14,101||IBP - reserved exclusively for beacons||14,100 kHz NCDXF/IARU International Beacon Project https://www.ncdxf.org/beacon/|
|14,101-14,112||All modes - automatically controlled data stations (unattended)|
|14,112-14,125||All modes (excluding digimodes)|
|14,125-14,300||All modes - SSB contest preferred segment||14,130kHz - digital voice centre of activity
14,195+- 5 kHz Priority for Dxpeditions
14,230 kHz - Image Centre of Activity.
14,285 kHz - QRP Centre of Activity
|14,300-14,350||All modes||14,300 kHz Global Emergency Centre of Activity|
|14.350||End of band|

What is amateur radio?
Amateur radio is a popular technical hobby and volunteer public service. As a licensed amateur radio operator, you are permitted to transmit and receive radio signals on frequency bands allocated for use by amateur radio amateurs. Amateur radio operators use these designated bands of radio frequencies for non-commercial exchange of messages, wireless experimentation, self-training, and emergency communications. A 1910 announcement by the then HM Postmaster General licensed “experimental wireless”, which still uniquely gives radio amateurs the ability to innovate without commercial or statutory controls even in the closely regulated environment of the 21st century. Amateur radio is the only hobby governed by international treaty.
Amateur radio operators use the amateur radio bands for a variety of purposes:
- Contacting people all over the world by radio which often leads to developing international friendships,
- Competing in international competitions to test the effectiveness of their equipment and their skill as a radio operator,
- Technical experimentation — many of the leaps forward in radio technology have been initiated by radio amateurs,
- Communication through amateur space satellites or with the International Space Station (which carries an amateur radio station),
- Providing communications at times of emergencies and undertaking exercises to maintain that capability.
There is no better way to explore the fascinating world of radio communications than by becoming a radio amateur.
