K1TTT MOF/LOF Propagation Program

• Text entry boxes on the right are for entring your Lat/Lon, the current SF, A, and K indices, and the month, day, and time. You can click on the map(only the rectangular format map) to enter Lat/Lon.
• The Buttons:
  • 'Compute' starts computation based on data in fields.
  • 'Next Hour' increments the time field by 1 hour and recomputes.
  • 'Now!' sets the current date and time and recomputes.
• The check boxes:
  • 'SP MOF' displays the short path MOF(red=10m, green=15m, blue=20m)
  • 'LP MOF' displays the long path MOF(red=10m, green=15m, blue=20m)
  • 'SP LOF' displays the short path LOF(red=160m, green=80m, blue=40m)
  • 'LP LOF' displays the long path LOF(red=160m, green=80m, blue=40m)
  • 'Rectangular' the default map projection
  • 'North Polar' converts map to a polar projection from the North Pole
  • 'South Polar' converts map to a polar projection from the South Pole
  • 'Polar QTH' converts map to a polar projection from your QTH
  • 'SUN' displays sun rise(solid circles) and sun set(open circles)
  • 'QTH' displays your QTH as solid white circle
  • 'Paths' displays great circle paths from your QTH
• Keyboard:
  • TAB and Shift-TAB now work to move through the data entry fields and pushbuttons.
  • ENTER works on the 'Compute','Next Hour', and 'Now!' buttons, even though the buttons don't look like they get pushed.

NOTE: the polar projections may take some time to generate depending on your machines speed. The North and South Polar projections take about 5 seconds on my 100 MHz Pentium, the Polar projection from your QTH takes about 15 seconds. I don't think I am using the most efficient method for generating these so hopefully I can speed them up in the future.
