Apparently not, as 710 is something else entirely. I guess I only get the Sacramento station (KQED) and the other is San Francisco.
Sacramento's PBS station is KVIE (channel 6 / 706). If you live closer to Sacramento than San Francisco, you probably wouldn't get KQED Plus - especially as it was originally San Jose's PBS station.
Do you get KCRB (usually channel 22 / 722)?
