nearly all of this market is in the United States National Radio Quiet Zone. In April 2012, then-owner Jones Broadcasting announced it was selling WAZM-CA to Gray Television. Gray changed its callsign to WSVF-CA on June 4, 2012. On June 1, 2012, Gray Television applied for and was granted a Notification of Suspension of Operations Request from the Federal Communications Commission (FCC), as Jones Broadcasting had no digital facilities built, and Gray preferred to relaunch the station as a digital-only operation clear of WAZM-LP's history (though it retains the license's previous history and FCC facility ID number). WAZM-CA's analog signal, operating at 21,900 watts, completely missed the major cities in the market, including its city of license. However, WSVF's digital signal covers virtually all of the market, and extends as far southeast as the adjacent market of Charlottesville. On July 17, 2012, Gray Television signed an affiliation agreement with CBS for WSVF-LD and two other low-powered stations WECP-LD in Panama City, Florida, and WIYE-LP in Parkersburg, West Virginia. As a result, WSVF-LD became the CBS affiliate for the Shenandoah Valley in October 2012. It is the first time CBS programming has been seen on a Shenandoah Valley station since WHSV-TV (then WSVA-TV) dropped CBS programming in 1963; since then, WUSA in Washington, D.C. had served as the default CBS affiliate for the Shenandoah Valley. However, CBS programming is aired on the station's second digital subchannel, while the Fox programming previously seen on WHSV-DT2 airs on WSVF's primary channel. This is to provide a high-definition signal for Fox network programming to the Shenandoah Valley; technical limitations do not allow any of WHSV's subchannels outside of the main ABC signal to air in high definition. WSVF is the second full-time terrestrial network affiliate in the area; WHSV has had the market more or less to itself since it signed on in 1953. In February 2013, WSVF's class A status was transferred from the former analog channel 25 signal to the digital station. Due to WSVF's link to WHSV, the same FCC must-carry rules that kept it off cable now forced its addition. The must-carry rules also give full-powered stations the option of retransmission consent, which allows these stations to request compensation from cable systems as a condition of carrying them. In this case, Gray has the right to require cable systems to carry WSVF as part of the compensation for carrying WHSV.
