EVMCHIRP Software

Peter's Phase II software 'evmchirp' contains the following files:

evmchirp.exe
The PC Windows executable file
evmchirp.cld
The EVM executable, which can be automatically downloaded by the PC.
evmchirp.hlp
The Windows Help file for the system. This includes all the setup information and the required hardware connections.

All you need to do is download the zip file, and unzip it into a suitable directory on your PC. Run the Help file to find out where to go from there.

Poslines program

There is also a range plotting utility, (see table for download) which allows you to enter positions of receiving sites with their delay times, and will plot lines of equal delay on which the transmitter must lie. It will also plot antipodal circles from long path - short path differential delays. This software is ideal for locating unknown transmitters.
