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.
