Integration

Electronic World atlas for Radio Amateurs. Scrollable World map with smooth zoom, DXCC territories, province/state prefixes, Grid Squares, CQ and ITU Zones in the rectangular, azimuthal and Globe projections, 3D relief, Gray Line, city and island index, unique hierarchical prefix database, local time with DST for all cities, islands and call areas, unique ionospheric maps.

Integrates with HamCAP, IonoProbe, Band Master, and many 3-rd party programs.

Prefixes
Call area boundaries and prefixes are shown on the World map in addition to the DXCC boundaries and prefixes. Each prefix has a hint with a country and province name. Click on a prefix to find it in the Prefix Database.

Zones
CQ Zone and ITU Zone boundaries can be switched on and off. Move your mouse over the zone label to see the official definition of the zone.

Grid Squares
The Maidenhead Locator map displays 2-character and 4-character grid squares. You can mark worked and confirmed squares and add comments to each square. The Grid Square calculator converts between the latitude/longitude and the grid square locator.

Azimuthal map
Rectangular, Azimuthal and Globe projections are available. The Azimuthal map center can be changed with a single mouse click to see how the World looks from a DX location.

Navigation
Zoom in and out, scroll or re-center the map, switch between the projections and turn individual layers on and off with your mouse. Antenna bearing anddistance for the point under the mouse cursor are shown on the status bar.

Gray Line
can be turned on and off, or shown for any specific date and time. Sunrise and sunset time is calculated automatically for the current point and for all gazetteer entries.

Prefix Database
Browse the visual, hierarchical prefix database that comes with DX Atlas. This database includes current and old prefixes of countries and provinces, prefix blocks allocated to club stations and reserved for special events, and much more. Each entry has a lot of associated data, including CQ/ITU Zone, Time Zone, DXCC territory and ADIF number. We have released our Prefix Database as a public domain dataset.

Gazetteers
DX Atlas includes a detailed City and Island index. Double-click on any island or city to find its location on the map, or right-click to see the details such as latitude and longitude, country, province, and city population.

Local time
is displayed for all territories, provinces and cities, for the current date/time and for the dates in the past and future. This function uses a database of Time Zone and DST changes since 1945.

Automation
3-rd party programs can control DX Atlas and even plot their own data on the map via COM or OLE Automation.

Ionospheric maps in DX Atlas

DX Atlas includes a set of dynamic, interactive ionospheric maps. Each map displays the selected parameter, such as the F2 layer critical frequency, D layer peak electron density, etc. The parameter value under the mouse cursor is displayed on the status bar, and various levels of shadows show how the parameter is distributed across the Globe.

If you had to drive from point A to point B, would you prefer to have the driving instructions or a road atlas? The task looks easier in the first case: you just follow your instructions, and you do not have to read the map. This works fine until you discover that the exit mentioned in the instructions is closed. Now you are helpless! You do not know what other routes exist. If you have a roadmap, however, you can easily find an alternate route. Ionospheric maps are like a road atlas to a DXer, they allow you to find 'alternate routes' even if the 'driving instructions' produced by the propagation prediction programs fail to work.

To use the ionospheric maps, one needs to understand how the ionosphere works. As you probably know, the F layer reflects radio waves, and the D layer is responsible for signal absorption. By checking the F layer's critical frequency along the path, you can tell if the high bands are open, and the D layer density gives you an idea how strong the signal is going to be. There is much more information that can be extracted from the maps. For example, chordal propagation is likely to occur in the areas where the F2 critical frequency (foF2) or height changes quickly along the path, and path bending can occur if there is a significant transverse foF2 gradient.

The more you know about the propagation mechanics, the more useful ionospheric maps are to you. Use your knowledge to interpret the maps, and use the maps (with a good book on propagation) to improve your knowledge. Propagation 101 by Bob Brown, NM7M is an excellent example of such book. You can download it from our Web site: Prop101.zip.

Internet Ham Atlas by SP6NVK

Welcome on my pages

The goal of the creation of this service was the gathering in one place and in the equal form basic data about all DXCC Entities.
Surely it is proper to find out something about the country of the correspondent or about the rare DX country, wherewith you just made the contact.
I supposed besides that from this service will enjoy also persons not being radio amateurs, either radio amateurs barely beginning the adventure of its life. Just for them intended is this part of the service which permits to seek the information according to geographical units. It is the first step in polished manners with the world parted into DXCC Entities. At every geographical unit show itself links to entities DXCC, which compose it.
A separate profile of the service are maps. They represent DXCC entities, countries or parts of geographical units (islands, administrative units etc.).
Classical maps always fascinated me, therefore are them here not a little. And will be increasingly. As that the progress will be not possible to avoid and to defend before him is meaninglessly - the part of maps is in the present form and the graphic stylistics.
I wish satisfactions at using this service.
Darek SP6NVK

Prefixes and callsigns
As the main prefix for the given DXCC Entity I fixed:

The official prefix assigned by the entitled administration, e.g. SP, OH0;
The prefix used by DXCC, e.g. KH5K;
One from many used prefixes arbitrarily chosen by me, e.g. DL (and not DJ or DK).
I will not interfere in discussions nor be change nothing in the case of prefixes „usually used” for some Entity, e.g. 3B8; 3B9.
Series of signs embrace all series admitted by the properly administration regardless of whether they are used and in what character are used, e.g. HF0 - Polish stations on Antarctica.
Series of signs contain only these exclusions (or inclusions) whose executed national administrations, up to the mark prefixes e.g. KL9 for American armies in South Korea.

Relations The Entity Û The Geographical Unit
Between The DXCC Entity and The Geographical Units occur following kinds of relations:
1. The Entity = The Geographical Unit:the state with the compact territory :

e.g. SP = Poland;the island fulfilling DXCC criteria e.g. JX = Jan Mayen.
2. The Entity = the part of The Geographical Unit (but not the political or administrative part):the part of the archipelago :

e.g. E51 = North Cook Is.;distant islands e.g. T33 = Banaba Island, 3D2 = Conway Reef, OJ0 = Market Reef.
3. The Entity Þ The Geographical Unit is not assigned: 

R1MV = Malyj Vysotskij Island.
4. The Entity = the dependent administrative unit or the dependency: the administrative unit:

e.g. OH0 = Aland Islands, EA6 = Balearic Islands; several administrative units or other not being Geographical Units e.g. EA9 = Ceuta + Melilla + Islas Chafarinas+ Penon de Velez de la Gomera + Islas Alhuceimas; Ceuta and Melilla are autonomous cities on rights as the province; the dependency or the oversea territory e.g. FO = French Polynesia, VP6 = Pitcairn Islands; the territory which does not accept the central authority H44 = Temotu Province (Solomon Islands – H4).
In this service such kind of the dependency became definite as the 1‑level dependence, and for the relation the dependency Û the main territory on adopted qualifications the province Û the metropolis. Formal and legal relationships in every case are different, and using qualifications reflect only the dependency relationship between these territories.
5. The Entity = the subordinate administrative unit or the dependency of the lower rung: the administrative unit:

 e.g. FO = Austral Islands - the part of French Polynesia; the dependency or the overseas e.g. FK/C = Chesterfield Islands.
In this service such kind of the dependency became definite as the 2‑level dependence, and for the relation the dependency Û the province on adopted qualifications The Entity Û the province. Formal and legal relationships in every case are different, and using qualifications reflect only the dependency relationship between these territories.
6. The mixed status - The Entity is subject the metropolis but is administered from the province: 

e.g. FO = Clipperton; it is subject directly to authorities in Paris but is administered by authorities residing in French Polynesia.
7. The Entity = 2 or more Geographical Units:
e.g. ZC4 = Akrotiri + Dhekelia, E4 = Gaza Strip + West Bank, FR/J = Bassas da India + Juan de Nova + Europe.
8. The Geographical Unit does not exist as The Entity but its create series of Entities:
e.g. G + GW + GM + GI + GD + GJ + GU = Great Britain, T30 + T31 + T32 + T33 = Kiribati.
9. The Geographical Unit and The Entity are identical but they have different names:
e.g. The Entity VQ9 = Chagos Islands but The Geographical Unit is called British Indian Ocean Territory.
10.The Entity is not The Geographical Unit nor political and one distinguishes itself only with the special status of administering (Entities formed according to criteria before 1998):
e.g. CY9, CY0, KH7K, KP5.
11. Entities appended according to the point 3 Rules DXCC (Special Areas):
e.g. 4U1, S0.
These divergences cause that the state which possesses on its own territory above 1 Entity, is not consequently same object as The Entity with such name!!! Thus The Geographical Unit France is not equivalent The Entity France, howevercontains The Entity France - but also Corsica, French Polynesia, New Caledonia and more Entities for whom France is a metropolis (all territories which are creating the Republic of France).

Maps
1. The main objective of the creation of this service was the gathering large quantity of various maps; mostly traditional on the paper. From here - except maps of countries/Entities - also maps of their parts, islands, administrative units and regional maps.
2. As the rule I accepted presenting of maps in files of the type GIF - the loss-free recording does not cause „impurities” on maps. In exceptional cases - very large files - placed are also maps in the JPG format, however with the comparatively small compression.
The structure of the catalogue with maps

Groups of maps
Below one represented 2 core groups of maps of this service: Geographic Units and DXCC Entitieswith possible variants of their searching.
In thematic groups: Maps of Poland, Other maps etc. the search happens characteristically for every from these catalogues.
