- INTRODUCTION
-
- Every effort has been made to make this the best and most
- accurate beam heading and distance program available. The
- author was prompted to write this program after several
- failed attempts to find an existing program that would work
- for all points on the earths surface. This program has been
- tested and found to work at the poles, exact antipodes, and
- for the same point on the globe. While rounding errors may
- exist, our tests have found the program to be very accurate
- at both great and small distances. (Tested accurate using two
- points 10 miles apart.) The most important thing is to be as
- exact as possible when entering the points.
-
-
- CONVERTING MIN/SEC FORMAT TO DECIMAL FORMAT
-
- As pointed out above, the more accurate the points entered
- the more accurate the results. So, lets go over how to
- convert from Minute/Second Format to Decimal Format. This is
- done by using the following formula:
-
- Decimal Format = Degrees + Minutes/60 + Seconds/3600
-
- Lets say your latitude was 32 degrees, 12 minutes, and 34
- seconds. In order for this to be used by the program, the
- format must be converted to decimal as follows:
-
- Decimal Format = 32 + 12/60 + 34/3600
- = 32 + .2 + .00944
- = 32.20944 Degrees
-
-
- NORTHERN/SOUTHERN LATITUDES
- EASTERN/WESTERN LONGITUDES
-
- In most cases you will also need to enter the hemispheres and
- meridians using a different format than is used by most
- books. Northern latitudes and Western longitudes should be
- entered as positive numbers. Southern latitudes and Eastern
- longitudes should be entered as negative numbers. Examples
- of this are as follows:
-
- 50.25 Degrees North latitude would be entered 50.25
- 139.00 Degrees South latitude would be entered -139.00
- 114.52 Degrees East longitude would be entered -114.52
- 79.34 Degrees West longitude would be entered 79.34
-
- You do not need to enter plus (+) signs as any number without
- a sign is assumed to be positive.
-
-
- PROGRAM OPERATION
-
- This program is completely menu driven and requires no
- additional documentation. The program itself is designed to
- run on all IBM personal computers and compatible. It has
- been tested on an IBM PC, XT, and PCjr using PC-DOS 2.1. The
- only file needed to run the program is QRBQTE.COM. To begin
- simply type QRBQTE from the default drive prompt.

-
- A FINAL NOTE
-
- The question has been asked, what does the name QRB/QTE stand
- for. Most radio amateurs are familiar with Q signals. So,
- the filename is a concatenation of two Q signals. QRB
- literally means "The approximate distance between our
- stations is _____ miles." QTE literally means "Your TRUE
- bearing from me is _____ degrees at _____ hours."
