Assuming your concept was valid, i.e. signal strength was a function
of distance by some formula (inverse square), the approach to follow
is called least squares. Look around for additional info with that
terminology.

I participate in a lot of transmitter hunts. I hadn't thought of it
but you are on to something. I wouldn't recommend finding a
transmitter using the method he wants to do it in, that would take too
much time. He would also need an attenuator to prevent full scale
readings.

If he wants to hunt with an omni, all he needs really is a step
attenuator and a receiver with an S-meter. Leave the GPS at home.

A faster method is with a directional or null antenna, attenuator,
map, protractor, and possibly compass so he can put the headings on
the map more accurately.

I was thinking of using GPS too, but here is how I would do it. I
have a 4 antenna doppler array that gives real time headings. The
array is mounted on my vehicle. The doppler unit sends four bit BCD
to a 16 LED heading indicator.

I would pull the BCD readings and send them to a notebook computer
with a mapping program installed and the GPS connected. The program
code would take the heading from the doppler unit, the receiving
position from the GPS, and superimpose it on the map. The code would
also have an "averaging algorithem" to throw out bad heading do to
reflections and such.

I would only do something like this to show how nifty you could find a
transmitter. Will I do this? Probably not, I already do it in my
head.
