   Amateur Radio ADF 73.023

    Amateur Radio ADF (Antenna Direction Finder) can
 be used to  quickly locate the correct heading for 
 a directional antenna.  The direction calculated 
 will be the shortest distance (as the crow flies) 
 between the latitude and longitude of the home QTH 
 and latitude and longitude of the selected country 
 or U.S. city/state.  To display the long path, double
 click on the 'Degrees:' label.  Except where additional 
 locations within a DXCC country are listed, the 
 antenna heading will be toward the center of the 
 chosen country.  (Exception: Russia points to 
 western Russia.)
 
   Upon clicking on a U.S. state button, the direction
 will be calculated from the home QTH to the center of
 the chosen state. Further narrowing of the direction
 can be done by selecting a city from the city list for
 that state.  When the DXCC list has been chosen, simply
 type in the country call prefix and the list will 
 automatically scroll to that prefix/country.  The DXCC
 list can be sorted by call sign or by country, by right
 clicking on the selection box and then selecting the 
 desired sort.
 
   Upon clicking on the GRID button, the direction
 will be calculated from the home QTH to the location
 of the entered grid (Ex: Both EL29 or EL29AB formats
 can be used).  
 
   The home QTH latitude and longitude parameters are 
 entered into the preferences window.č
 
 Additional features:
 
 1.  U.S. call area map.
 2.  U.S. band graphs.
 3.  World map with DXCC country locator list.


  Noteč: XP and other users with machines above W98
         should start and test the HamADF_XP.exe
         version included in the zip file to see
         if it works properly on their machine.
         If it works ok, right click the program
         icon and change the path to HamADF_XP.exe .     

  NoteČ: The user's degrees.minutes should be actual 
         degrees.minutes: dd.00-59 (not a percent 
         of 60 minutes: dd.00-99).  If your 
         degrees.minutes are in the form dd.00-99,
         then multiply the .minutes by 0.6 to get
         actual minutes.
         (Ex: [percent degrees.minutes: W°95.75] =
          [actual degrees.minutes: W°95.45]
          (.75 x .6 = .45)).
