True.  I agree.    PHG is not supposed to be interpreted as a line
in the sand where RF from a station just ends.  PHG is just
a way of reporting relative station capability.   Just sort or
providing information that is available.    Interpreting
the overlapping signal contours and deciding what  is the most
probable emitter of interest remains a  human intuition task based 
on all of these and other relative data inputs on the interferring
jammer or signal.

For packet you are absolutely correct, that the easiest thing is
to just decode it.

But the reason I mentioned the APRS signal localizing technique 
is because so far no one has been close enough to the signal
to decode it.  ANd the APRS Omni-Signal-Strength method can
solve that part of the initial problem.  it can almost instantly tell 
where the signal generally is so tht someone can drive over there
and monitor for one good packet and end the problem.

Thanks for letting me clarify how to use this 
technique.  Also, DFing it is good practice.   THink of this
as an opportunity to practice signal location for those times
when it is not as easy as just decoding the packet...

Just some thoughts...
