Using the geographic coordinates for each, I've "translated" the FCC

procedure for determining the distance between two transmitters ( per FCC

73.208) into Excel formulas. Excel gives identical distance results to the

"fill-in" form provided in www.fcc.gov/mb/audio/bickel/distance.html . But

there is no comparable formula in the FCC R&R for determining the bearing

(azimuth) between the stations relative to true north, although the FCC's

fill-in form does provide azimuth.

My problem with using the fill-in form is that I have hundreds of

computations to make and I'd spend untold hours using the fill-in form for

one pair of stations at a time. If I can get a formula for determining the

azimuth relative to true north based on the geographic coordinate pairs, I

can whip this puppy in no time at all with Excel.

Any solutions or suggestions would be greatly appreciated.

Thanks and regards,

PJF
