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.

I hate to tell you this, because you will simply deny it anyway... but here
in Korea, there are only a few full power stations, most of those in Seoul,
Deagu and Busan. The rest of the country is served by literally hundreds,
perhaps thousands, of 20-40 watt translators. Most of the translators can
be heard very easily in many towns/villes on cheap pocket radios and mp3
players that have FM radios in them. I can personally sit here in my house
(houses here are almost 100% made from concrete and steel rebar) and hear at
least 4 translators for EACH of the network stations (KBS, MBC, CBS, etc.),
with the closest of those being about 12 Km away in Pyeongtaek, and all of
this on a little Sony pocket radio. There are three AFN plants that can be
heard as well: the local one, 5 Km away at the back of our base, running 40
watts, one from Osan, about 15Km away, running 30 watts, and the "big" one
in Seoul, 80 Km away, running a whopping huge 1200 watts! I don't know what
sort of oddball signal black hole you have there, but in the rest of the
real world, low power does work. Also, I'm sure you know that there are
many places on the east coast where a 6KW plant is as big as it gets..
