Hi Mike;
In general your output power will have to go from lets say 100 to at least
400 to see any real difference.  Going from 100 to 250 would be relatively
meaningless.  Similarly going from 500 to 900 output wouldn't do much
either.  If possible you can get much more improvement if you upgrade the
gain of the antenna than increasing the power.  The nasty problem is that it
is much easier for many on this list to upgrade the power than to try and
upgrade the antenna.
You may get lots of different opinions however.
