- This is !QTHloc_GC, version 1.00 (3 Jan 1992).
- ***********************************************
-
- The program is intended to be a "Pop-Up" calculator
- for conversions between any of the following:
-
- QTH locator (Maidenhead, eg IO92AB)
- National Grid Reference (NGR, eg TQ123456)
- Longitude & Latitude (deg, min, sec etc)
-
- Two areas of the calculator are available in which
- to enter one of the above:
-
- Home reference
- Distant station
-
- A value typed into any of the entry boxes will,
- when the adjacent OK box is clicked, result in the
- other boxes in that area being updated with the
- corresponding values. The other boxes in the area
- being edited will be blanked if the entry was
- invalid.
-
- If valid entries exist in both the Home and Distant
- areas, then Great Circle path calculations are
- performed to provide the distance and bearing of the
- distant station from the home reference. These are
- displayed in the Great Circle Path area.
-
-
- Notes:
-
- All parts of long/lat must be filled in
- before the corresponding OK box is clicked.
-
- The E/W & N/S boxes are simply toggled between the
- values by pointing and clicking.
-
- Locator & NGR may be entered by pressing return.
-
- Entries cannot be made in the Great Circle Path
- area.
