General Comments

Delaware does not have any public radio stations operated by Delaware-based broadcasters.  The three public radio transmitters located within the state are operated by stations in Maryland and Pennsylvania.  These broadcasters provide service to over 96% of Delaware's population.

FM Service

Since the 1989 PTFP study, two transmitters have been constructed which substantially expanded the reach of public radio.  The most significant improvement in coverage occurred in 1991 in Kent County with the installation of WRTX Dover which repeats programming of WRTI Philadelphia.  The second new station, WSDL, located in the southeast corner of Sussex County, was installed in 1997 to enhance the coverage of Maryland station WSCL.  WSDL is licensed to Ocean City, Maryland. Its transmitter is located in Roxana, Delaware. WSCL is licensed to Salisbury, Maryland. Its transmitter is located in Seaford, Delaware. 

The percentage of Delaware residents receiving a public radio signal has increased from 84% in 1989 to 96.4% currently, and the unserved population has decreased from 94,000 in 1989 to 27,882 today.  

AM Service  


Service from Adjacent States

As noted, all public radio service in Delaware is a rebroadcast of program services originating from Philadelphia, Pennsylvania, or Salisbury, Maryland.  A high school operated Maryland station, WKHS, repeats the programming of WXPN Philadelphia during overnight hours, on weekends and during the summer months.  WKHS serves portions of Delaware’s New Castle and Kent counties.  

Unserved Areas

Region A  

New Castle County in northern Delaware receives public radio signals from stations in Philadelphia. The entire unserved population of Delaware (27,882 people) reside in northwest New Castle County.  Extension of service to this area is hampered by the presence of a channel 6 TV station in Philadelphia.
