(meteorobs) Searching for a FM station

[stange34 at sbcglobal.net]

Whether or not their are any unused frequencies is not the problem.

The problem is to find which stations are transmitting a carrier that you 
are not receiving DIRECTLY, but could receive indirectly by scatter only.

Think of it this way......

This is likened to being behind something that blocks the direct wave.... 
e.g., Hill, Mountain, Bldg., in a pit, etc. but where the scattered signal 
can reach you because it is at a much higher elevation and a steeper angle 
down to you.

Also sometimes the yagi can be aimed to null out a station (broadside), but 
could still detect a reflected signal from another direction from a fixed 
object or structure.

There are many physical variables here that must be experimented with. That 
is part of the fun......
