Colin's Software Page
Currently I am including here an RF propagation calculator, an audio WAV file to embedded code converter, a schematic capture program, and an IRC client. I have plenty of other interesting applications but they are either not yet ready for release, or are now obsolete... I hope to add more applications from time to time.
RFPROP
Description
RFProp is a Windows propagation calculator for the transmission path between an RF transmitter and a receiver. It is aimed mainly at free-space and space-wave applications, such as are encountered in VHF, UHF and microwave communications, and also in satellite communications. A knife-edge diffraction calculation is also included which when enabled allows the effects of a hill or other obstruction to be taken into account.

Older Versions
Version 1.10 (January 4 2004)
32 bit version of RFProp, with an improved NSIS installation program. Non-standard .ASC file extensions were replaced by .TXT, and the units for "Margin at spec. range" have been corrected from m to dB. File-save dialog was a considerable improvement on the old 16 bit one. Installer updated in 2005 because of false positives from AVG on the old one.Download
