One thing to keep in mind is that "Chinese" communities are differentiated in the Bay Area by origins and by language spoken. The original 19th century immigrants and their descendants were/are Cantonese speakers. They're concentrated in San Francisco and in the bayside East Bay. More recent immigrants, who tended to come from the People's Republic to attend university and then stayed, are Mandarin speakers, and are more likely to be in Silicon Valley. It's my understanding that Cantonese and Mandarin, while described in English as dialects, are really quite distinct languages. KVTO (and KEST) are programming to the Cantonese-speaking audience for the most part. I don't know of any South Bay stations programming entirely in Mandarin. (After I went back to working in downtown San Francisco, I wasn't in the South Bay much.) There are three stations programming in Vietnamese, which, of course, is a distinct community of its own, speaking a language entirely unrelated to the Chinese languages.If 560 were to continue, I'd expect KVTO to try and move frequencies. That's a 5-fold increase on power and a lot more ground conductivity. Given the large Chinese population in SF, it would increase listenership in areas where the 93.7 translator is too weak.
Also note that KVTO and KVVN (1430, Santa Clara) have the same ownership. KVVN is in Vietnamese; KVTO aims for Cantonese-speaking listeners.
KVTO's translator, K229DD, is on the Sutro Tower. So it's just fine in San Francisco and the areas it needs to cover in Berkeley, Emeryville, and Oakland.
