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 HamCAPIonoProbeBand Master, and many 3-rd party programs.

Ham prefixesPrefixes
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.
CQ Zones, ITU ZonesZones
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.
Azimuthal mapGrid 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 mapAzimuthal 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.

Antenna bearingNavigation
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, sunrise and sunsetGray 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 lookupPrefix 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.
Cities and islandsGazetteers
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.
COM and OLE AutomationLocal 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.
COM and OLE AutomationAutomation
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
