path between an RF transmitter and a receiver. It is aimed mainly at
short range radio applications, such as in-building LAN and
point-to-point links up to a few km where there is a direct line-of-sight
or a simple diffraction profile, or a modified range law model, but it
can also support calculations for satellite, aeronautical and space
communications where the line-of-sight model can be applied. It is
useful to both ham operators and radio professionals.

The knife-edge diffraction calculation option allows the effects of a
hill or other obstruction to be taken into account. Loss factors can be
included, e.g. building penetration loss.

Maximum range and path budget margin are rapidly calculated and viewed
while modifying the input parameters conveniently using the main graphic
window. The parameters are displayed against a bitmap of radio stations
and a hill to visually aid entry of the various parameters. A text-mode
window can be opened up to list the results, with additional information,
and then output to an Ascii file. A built-in help file includes
information about the various parameters and calculated results and
includes further information about changes in this version.

Special requirements: Windows 3.1, also 95 & NT compatible.

Changes: Bugs fixed, added window sizing and font selection to improve
compatibility with user systems, added some intermodulation
calculations.
