My local listener-supported radio station, WVUD, has a folk
program called Roots each weekday morning from 9 to noon,
eastern time. During the school year it runs from 8:30 to
11 am. Each day has a different dj with a slightly
different take on folk.

Wednesday evenings they have a Celtic show. Saturdays they
have two bluegrass/oldtime/country programs, one from 10 to
12, and one from 12 to two pm.

I think the URL is WVUD.org
