Move-in to Washington
As a result of the Federal Communications Commission (FCC)'s 2016–17 spectrum reallocation incentive auction, channels 24 and 30—occupied by WNVC and WNVT, respectively—became available in the Washington market in 2018. WDCO-CD applied to take over WNVC's channel 24 facilities at its tower in Merrifield, Virginia, which would place it firmly in the Washington market, while WIAV-CD applied to move to channel 30. After WNVC was unable to find a channel-sharing partner and went off the air, it sold the tower and transmitter building. Left without a transmission site, WDCO-CD moved to temporary low-powered facilities shared with WIAV-CD at the WRC-TV (channel 4) tower in northwest Washington, and reapplied to permanently build there.[5]
The new WAZT-CD later relocated from Winchester to Blue Ridge Mountain in extreme southern Jefferson County, West Virginia, near the Virginia–West Virginia state line but also within the Washington market. After an additional "hop" to a tower in Leesburg, Virginia, this license was also moved into Washington proper and sold to Weigel Broadcasting, who operates it as WDME-CD.[9]
On June 25, 2020, Venture Technologies Group filed an agreement with the FCC to sell WDCO-CD and WIAV-CD to Sinclair Broadcast Group for $8.5 million.[10][11] The sale was completed on October 15,[12] making them Sinclair's second and third properties in the Washington market, alongside WJLA-TV. On the same day, WDCO-CD and WIAV-CD flipped to Sinclair's TBD multicast network. WAZT-CD was not included in the sale and continued to air Jewelry TV programming; it was later sold to Weigel Broadcasting and is now WDME-CD.
Sinclair's express intention for the purchase of the two stations was to convert WIAV-CD to Washington's first ATSC 3.0 broadcaster. WDCO-CD is to continue ATSC 1.0 service and honor the existing channel-sharing agreement with UniMás affiliate WMDO-CD (channel 47).[13][14] To clear the way for ATSC 3.0 conversion work, WMDO-CD switched its channel-share from WIAV-CD to WDCO-CD at the end of 2020.[15]
Sinclair subsequently commenced ATSC 3.0 operation over WIAV-CD on March 25, 2021.[16]
WDCO-CD and WIAV-CD satisfy the requirement that Class A stations broadcast at least three hours per week of locally produced programming by airing WJLA's weekday 5 and 6 p.m. newscasts on a two-hour delay from 7 to 8:30 p.m.[17] The entire TBD schedule remains available on streaming and over-the-air on WJLA-DT4 and Baltimore's WUTB.
