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.

I doubt they lost any significant number of listeners in the metro area,
since all stations at that point were on an equal playing field, and
already had their audiences. I know that at my place on the far east end
of the county I noticed absolutely no difference in signal quality.


Laws of Physics step in here... the average home or at work listener's
receiver is not sensitive enough to pick up much under a 65 to near 70 dbu
signal, so they weren't listening to anything.
