Even 6,000 watts of Fm in stereo is scratchy..

Oooh; don't tell these guys:

HAAT of the antenna structure makes a lot more difference than EIRP.

True to some extent. I was involved with a station in the LA area that had
500 watts at over 1000 feet, HAAT, and about 2000 feet over the LA Basin.
What we had was a bad signal over a very large area, We went off the side
of a mountain, down to to 300 feet at 6 kw, and the ratings with the same
format trippled.

I had to fight some folks who just looked at maps and did not understand how
radio is listened to in order to ram this through.

In this case, power was much more important, as below a certain power level,
height gets coverage without any intensity.

With
antenna heights approaching 2000' HAAT, the Portland, OR FM's put a good
stereo signal out to about 20 miles when running only their 10W exciters
(which has been done on a few occasions when mains power was out over a
wide area for an extended time).

And likely nobody was listening... that is too little power to generate any
audinece.
