Most of SD county does not receive a listenable signal from KNX based

what signal level is required to get ratings.

I get them just fine,
maybe you're thinking of the Anza Borrego desert communities

No, I am thinking of the fact, verified by dozens of ratings periods in
many, many markets that shows that AMs get over 95% of their in home and
at
work listening (70% lof the total listening on average is in home or at
work
where ZIPs are tracable) is in areas where the signal is 10 mv/m or
greater.
Since only a tiny amount of shoreline has that intensity from KNX, there
is
pretty much nowhere that the signal is usable by the average,
non-hobbyist,
listener. Which is part of why they have essentially no in home or at
work
listening at all in SD County (the county is the metro for Arbitron).

You are so full of crap. You don't know what you are talking about at
all.

Yeah, you are right and the measured behaviour of millions of persons over
the period of a decade or more is wrong.

San Diego is one of the markets where listening location vs. signal strength
has been analyzed, going back to 1998 and covering 39 survey periods and
nearly 100,000 listener diaries.
