**MATLAB toolbox: FM Radio (87.5-108 MHz) Field Strength Calulator
for Matlab using ITU 1546-1 standard**

This is a small toolbox that allows radio station engineers to make
quick calculations of expected field strengths.

This toolbox can calculate the expected field strength of an FM Radio
transmitter, when You know the power of the transmitter, the distance to
it, and it's effective antenna height.

You can also calculate the inverse, where You want to know at what
distance is the field strength e.g. 54 dBµV/m, knowing the transmitters
power and effective antenna height.

There is also a tool that allows You to calculate the field strength
at reciever antenna height different from the standard (usually 10m) representative
clutter height.

Using the graphical tools of Matlab, You will be able to view results
like this (created using the demo1.m included in the files to download)

The solid line is for 50% time probability of interference, the dashed
line is for 1% time probability of interference.

Click here to get to the files... download everything
to a new directory, and add the directory to Matlabs path.

You should then be able to see it when typing "help" in Matlab.

This toolbox is written for Matlab 5.3 (R11). I have not tested it on
later versions, but this is not rocket science, so I don't see why this
shouldn't work. Anyway, there is only one way to find out...

Good luck !
