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,

That sounds like multipath in the RF plumbing. Did you tune for minimum
Synchronous AM?

Every necessary step was taken... including a rebuild on Johnstone when
the station was purchased. This was simply a case of too little power,
although it theoretically covered a great distance. The power was just
not enough anywhere to penetrate homes and buildings.

Where was the beam tilt aimed?

At the populated areas, not the mountain, but this was a single bay, so it
really was only optimized to comply with downward radiation for OSHA
purposes. This was just too little power. Everything was designed right, and
over the course of a number of years, three different antennas, both side
and pole mount, were tried. It was so obvious that it was simply too little
power... so moving down to the valley floor produced the right results and
within one survey period saw a dramatic increase in listening.
