Primary and Secondary Administrative Subdivisions
When you enter a new callsign in the Capture window or in the Main window's Log QSOs tab and then strike the Enter or Tab keys, DXKeeper will determine whether ADIF defines Primary and Secondary Administrative Entities for the callsign's DXCC entity, and if so limit your your choices to the valid codes that ADIF defines for each. US operators will have little difficulty selecting the correct Primary code -- its the standard 2-character state abbreviation (that now includes DC!), but its much harder to remember the correct county spelling to type into the Secondary box while in QSO with a US station. And then there are Russian districts, Japanese Cities and Guns, New Zealand counties...
To overcome the fact that no one can memorize all these codes, DXKeeper lets you choose a Primary or Secondary Administrative Subdivision from a list of full names; when you click on a full name, the appropriate code is placed in the correct Main or Capture window selector. Suppose you're logging via the Capture window, have typed HA1DX ito its call box, and struck the Enter key. Hungary has Primary Administrative Subdivisions called megye, but does not have Secondary Administrative Subdivisions. Click the down-facing black triangle to open Capture window's the megye selector (just below the name box), and a list of megye codes will appear. Unless you're Hungarian, you probably can't relate these to where HA1DX just told you that he lives -- so click the ? button to the left of the megye selector. This action displays a window titled Capture Administrative Subdivision Selector (Hungary). The top-most panel in this window provides Code and Name selectors. Click the Name selector's down-facing black triangle, and you'll see a list of all Hungarian megye; click on the appropriate one, and its code will be placed in the Capture window's megye selector.
Since Hungary doesn't define Secondary Administrative Subdivisions, the Code and Name selectors in the Capture Administrative Subdivision Selector (Hungary) window's lower Secondary Administrative Subdivision panel are empty. But were you to enter a Ukrainian callsign in the Capture window, the Capture Aministrative Subdivision Selector (Ukraine) window's Primary Administrative Subdivision panel would offer you a choice of Oblasts, and after you'd selected an Oblast its Secondary Administrative Subdivision panel would offer you a choice of Districts within the selected Oblast. Or if you logged a US callsign in the Capture window, you could select a state, and then select a county within that state.
The Awards panel in the Main window's Log QSOs tab provides similar facilities for selecting and logging Primary and Secondary Administrative Subdivisions -- with one additional capability. Suppose you click on Canadian QSO in the Log Page Display. With the Awards panel visible, you'll see an active province selector (and an inactive selector labeled sec sub, as Canada doesn't define Secondary Administrative Subdivisions). Click the ? button the right of the province selector, and the Main Administrative Subdivision Selector (Canada) window will appear, with its Primary Administrative Subdivision panel ready to let you choose a Canadian province by code or by full name. Now click on a US QSO in the Log Page Display; if a state and county were logged with this QSO, their full names will appear in the Main Administrative Subdivision Selector window -- which now serves as a decoder for QSOs in the Log Page Display that specify Primary and Secondary Administrative Subdivisions.
ADIF considerations
ADIF defines the District of Columbia (DC) as a Primary Administrative Entity of the US. DXKeeper's WAS report treats QSOs with stations in the District of Columbia as being in Maryland; its Worked All Counties report treats QSOs with stations in the District of Columbia as being in Maryland's Washington County.
ADIF defines Newfoundland and Labrador (NL) as a Primary Administrative Entity of Canada, replacing the previously separate provinces of Newfoundland and Labrador.
ADIF defines the 28 Alaskan Counties enumerated in
so these are what DXKeeper expects you to log in Alaskan QSOs. DXKeeper's Worked All Counties report automatically maps these counties to the correct Judicial District and reports your County progress accordingly.
