Each country of the world has the right to form the call signs of amateur radio stations in its own way from the blocks of prefixes allocated to it. In most cases, with some variations, the "territorial" principle is used, when different prefixes are allocated to different administrative-territorial entities of a given country or groups of such entities (provinces, states, departments, etc.). In this case, the country is usually divided into several so-called "amateur radio regions", which differ from each other by the prefix number. This is done in Russia, Finland, Italy, USA, Japan and many other countries. In other countries, prefixes are allocated to different administrative-territorial entities that differ not in numbers, but in initial letter combinations (for example, in the UK). But whatever system for amateur call signs is used by Communications Administrations, they tend to allocate different prefixes for those parts of the country whose unique identification is essential for amateur radio purposes.

Here we come close to the concept of "territory on the list of the DXCO diploma. The DXCC diploma ("Worked with a hundred territories of the world") is one of the most popular and prestigious amateur radio diplomas. Some countries are included in the list of credit territories for it, and some -" in parts". The rules by which it is possible for one country to have several credit territories are given in the regulations on this diploma. It should be noted that a significant part of them are islands located at a noticeable distance from the main territory of the country. Thus, Russia is represented in this list by six credit territories: the European and Asian parts of the country (according to the criterion - different continents), the Kaliningrad region (separated by the territory of foreign states), the Franz Josef Land archipelago (a remote group of islands), Maly Vysotsky Island (leased from a foreign state), Antarctica (Russian stations).

The table shows a list of prefixes of the territories of the world for the DXCC diploma and additional information regarding these territories - the continent on which they are located, and conditional zone numbers according to the lists of the International Telecommunication Union and the WAZ diploma. This data is of interest to diploma hunters and contesters. Territories are listed in alphabetical order of the "main" (most commonly used) prefixes assigned to that territory. For prefixes not included in this table, one should use the information from the table of prefixes of the International Telecommunication Union, which was given in the April issue of the magazine for this year. For countries located in several zones at once, the following symbols are given in the table:

A - ITU zones 33, 42, 43, 44
B - zones WAZ 23, 24
C - zones WAZ 14, 16
D-zones ITU 67, 69-74
E - zones WAZ12,13, 29, 30,32,39, 39
F-zones ITU 12,14
G-zones ITU 30,31
H - zones ITU 28, 33
I - ITU zones 32, 33
J-zones ITU6, 7
K-zones WAZ 3,4, 5
L-zones GSh 61, 62
M-zones ITU1.2
N - zones ITU 5, 75
O-zones ITU 12, 13, 15
P-zones GSh 61, 63
R-zones ITU 19, 20, 29,30
S - ITU zones 20-26, 30-35, 75
T-zones WAZ 16-19, 23
U-zones ITU 29-31
V-zones ITU 2-4, 9,75
W-zones WAZ 1-5
X-zones ITU 55, 58, 59
Y - zones WAZ 29, 30
Z-zones ITU 52,54.

The names of the territories in the table are given as they are usually indicated on receipt cards - in English.

The prefixes given in the first lines of the table, starting with the number "1", are unofficial - there are no such blocks in the original ITU table, as well as blocks starting with the number "0". Such prefixes are sometimes used by amateur radio stations in situations where the belonging of a territory to a particular country is either not defined or disputed and there is no unambiguity about who needs to get permission to work on the air from this territory.

Antarctica is considered as a single international territory in the list of the DXCC diploma. For brevity, only one prefix is mentioned in the table - Chilean (CE9). Russian stations operating from Antarctica use callsigns from the R1 ANA block - R1ANZ, Ukrainian ones - with the EM 1 prefix, American ones - from the KC4USA - KC4USZ block, etc.

In the table for Turkey, the continent is AS (Asia), a part of Turkey (TA1 prefix) is located on the European continent, but it is not considered a separate territory for the DXCC diploma.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Neutrino against caries 02.10.2015

American scientists from the Indiana University in Bloomington and the University of Southern Utah have found that the trillions of neutrinos that permeate the human body every second without harm to health are involved in the formation of most of the fluorine in the universe.

Fluorine occupies a place in the periodic table between oxygen and neon, but it is relatively rare in the Universe. To find out its origin, astronomers examined 79 stars using the 2,1-meter telescope of the Kitt Peak National Observatory in the Arizona desert (USA).

Scientists have been trying to find hydrogen fluoride that can absorb infrared radiation and leave a mark on the star's radiation spectrum. As a result, fluorine was found on 51 stars, and its source, based on the concentration, can only be neutrinos that create this element during supernova explosions.

During this process, a fair amount of neutrinos are released - about 10 to the 58th power. Some particles manage to knock out a proton or neutron from some of the nuclei of neon atoms in stars, resulting in the formation of fluorine.

It turns out that neutrinos have made a great contribution to the fight against caries, because it is fluorine that is the main element of toothpastes. However, some people do not agree with the conclusions of astronomers: scientists from the Lund Observatory (Sweden) have previously discovered a much lower concentration of fluorine in the stars.

Swedish astronomers believe that fluorine is formed not at all because of neutrinos, but as a result of nuclear reactions of red giants that burn hydrogen and helium. The truth can be established by correctly determining the temperature of the studied stars.

Hydrogen fluoride decays at high temperatures, so the spectra of warm stars show less fluorine than the spectra of cold ones. Scientists observing the discussion from the outside note that it is the neutrinos of supernovae that provide the Earth with the presence of up to 2/3 of the amount of fluorine and, therefore, provide people with protection from caries.
