I'm in the Philly area frequently and listen to WXPN as soon as it becomes available- U Penn station I believe and they do have a vinyl hour or two every day around mid day and yes it is an excellent station as are all the member supported stations.
Up in my neck of the woods in north Jersey 90.7 WFUV - Fordham Univ. does something similar as does Centinary college in Hackettstown both very similar in format to WXPN
