DavidKaye said:Given the patterns shown in the 2005 plots, KTRB's pattern would be fairly simple to produce. I mean, heck, this is nothing compared to the engineering mess that is KTCT 1050 (the old KOFY) or the defunct KWUN 1480, which were nightmares. But KTRB, by contrast, is a piece of cake.
What I don't understand at all is the Sunol site. It's southeast of SF not northeast as the KTRB specs showed when the station was being proposed. I don't know what kind of nulls it was supposed to produce, but I'd suggest that Sunol made it extremely complicated given that a null to
That's what leads me to believe that there was something else in play besides the desirability of the site, since as far as I've read on the issue, Sunol is not a desirable site at all.
The night pattern needs to be far removed from the population areas around the bay so that it can "open up" and cover everything from Marin County to Santa Clara County. As designed, the usable night signal barely covered San Jose and was severely nulled as you moved towards Campbell.
A tower site on the bay would miss all of the South Bay, and also the northeastern areas towards Vallejo. And because the pattern would not be able to open up enough, even parts of the north bay areas would be sacrificed.
The biggest obstacle to the south is XEMO in Tijuana. It requires enormous protection by night. And there are multiple restrictions on first adjacent channel overlaps, too. So the site, ideally, has to be right about where it is... or a bit to the south of that location if more Santa Clara County coverage is desired.
