For example, the LA stations do well in ratings in the Riverside market
and
the Ventura / Oxnard market. Advertisers neither pay extra for that added
delivery outside the LA metro, nor do they count LA buys against the
delivery in Ventura, for example.

If they buy Riverside (about the 30th market) they send orders to the
local
stations. If they buy Ventura at all (about market 120 and not often
bought)
they don't factor in LA stations.

That's insane. Everybody knows KNX covers from Mexico to Arizona to
the Central Coast. That's a factor, even if the books aren't.

Daytime, KNX covers from northern San Diego County to mid-Riverside County
to Southern Ventura County.

At night, due to, first, skywave / groundwave cancellation, the groundwave
coverage is much less than that... and the skywave coverage is pretty much
ripped most of the time due to the Mexican stations that are now operating
on 1070, especially the one in Cd. Obregón Sonora.

Advertisers do not buy outside the local metro, so the coverage, what there
is, outside LA and Orange County, counts for nothing to the business side of
KNX.
