WSAK

The Shark is an American FM radio Classic Hits-formatted duopoly in the Seacoast Region of New Hampshire, United States. Its two stations are WSAK (102.1 MHz; Hampton) and WSHK (105.3 MHz; Kittery, Maine), with broadcast studios located in Dover. The station's program format is almost exclusively classic hits. A few specialty programs are carried: The House of Blues Radio Hour with Dan "Elwood Blues" Aykroyd, and "The Reporter's File", a public affairs program, both on Sundays. The station was previously the only New Hampshire station to carry the syndicated Bob & Tom Show morning show. It no longer carries that program, instead using its own local DJs on The Shark Morning Show.

The station is owned by Townsquare Media. It formerly broadcast as "Arrow", on the same frequencies and with a similar format, but using call letters WXBB and WXBP. The change to the new name and call was made in March 2000.Citadel Broadcasting acquired the station in August 1999 when it purchased Fuller-Jeffrey Broadcasting Companies. Citadel merged with Cumulus Media on September 16, 2011.
