WRDV This is a new one to me ..Thanks to Seán Kennedy for hipping me to it.
WDVR and WRDV have some good jazz on. WRDV is in Warminster with repeaters in Phila., Bristol, Bensalem, and other places. WDVR is in seargentsville, NJ just above Trenton and much closer than Scanton.
WUSR broadcasts from the campus of the University of Scranton at 99.5 FM. They play jazz weekday afternoons (and blues from 4-6pm), and Mark Webber's program, Sunday Jazz, airs Sunday from 4-7pm. Sunday Jazz focuses on reissues from the 50s and 60s (although he usually plays a little Bird and/or Pres as well.)
