National Public Radio (NPR)

The best radio that I have come across.
If u are in the bay area you can tune into 88.5 FM, which is the KQED-FM.
Their non-intrusive way of advertising, the worldwide (BBC news at 9 pm),
and the daily morning biz news and the "Perspective", have been really
good.
Here are the timings of some of the good programs:-
- BBC world news at 9pm (daily)
- "The perspective" at 7.30 am (daily)
- "Commonwealth club of California" 8 pm (every friday)
- "The voices this week" at 7.05 am (every sunday)
will keep adding to this list as I found more.
