WMDO-CD: A History of Washington's Spanish-Language Television Evolution
The story of WMDO-CD is a complex journey through the shifting landscape of Washington D.C. broadcasting. From its humble beginnings as a low-power translator to its role as a key provider of Spanish-language content, the station has navigated regulatory hurdles, frequency shifts, and the digital transition over nearly five decades.
The Early Years and the Fight for Channel 14
The station first entered the airwaves in 1976 as W14AA on UHF channel 14. Originally owned by the Central Virginia Educational Television Corporation (CVETC), it served as a rebroadcaster for PBS member station WNVT. Because WNVT's primary transmitter in Independent Hill, Virginia, was difficult to receive in the densely populated areas of the Washington metropolitan area, W14AA provided a necessary signal boost.
During this era, CVETC attempted to move the vacant full-power allocation of channel 14 to Fairfax. This move sparked significant controversy, as channel 14 was the last available commercial allocation for Washington. Opponents, including District of Columbia Mayor Walter E. Washington, argued that the city was underserved and that the channel should be reserved for a minority-owned station. While the request was denied, a compromise led to the allocation of channel 56 to Fairfax, which became WNVC. Consequently, W14AA became unnecessary for PBS and was used to broadcast Congressional hearings until June 1981.
Transition to Spanish-Language Programming
In June 1980, Los Cerezos Television Co. launched KA2XEH on channel 56, relaying programming from the Spanish International Network (SIN)—the precursor to Univision—via a satellite feed from KWEX-TV in San Antonio, Texas. These stations were known as satellators, a term for translators that repeat a station's signal via satellite under experimental FCC licenses.
Following a relaxation of FCC rules, Los Cerezos purchased W14AA in July 1981, bringing SIN programming to the frequency. While Los Cerezos attempted to move the station to Wheaton, Maryland, to align with their radio station WMDO (1540 AM), these efforts failed. By October 1, 1981, the KA2XEH license was deleted to make room for WNVC.
Frequency Shifts and the Path to Class A Status
As the broadcast environment evolved, the station underwent several technical and identity changes:
- 1988: The station moved to channel 48 and became W48AW.
- 1995: The call letters changed to WMDO-LP.
- 1998: The station moved to channel 30 to accommodate WRC-TV's digital signal launch on channel 48.
- 2001: The station became WMDO-CA, reflecting an upgrade to Class A status, which provides more permanent protection against interference.
Contrary to common belief, the WMDO callsign was not derived from the Telemundo network, but from its shared ownership with WMDO radio. This partnership ended in 1999 when the television station was sold to Entravision.
The Entravision Era and Network Affiliations
Under Entravision's ownership, the station faced further signal challenges. In 2003, WMDO-CA moved to channel 47 to allow WNVT to launch its digital signal on channel 30, a move Entravision claimed resulted in a 45% loss of audience due to a weaker signal.
A pivotal shift occurred on January 1, 2006, when Entravision entered a 16-year joint sales agreement (JSA) with Univision Communications. Under this deal, the Univision affiliation moved to WFDC-DT, while WMDO-CD joined TeleFutura (later renamed UniMás). This agreement remained in place until December 31, 2021.
Digital Transition and Spectrum Reallocation
The transition to digital broadcasting was fraught with interference. In 2009, WMDO-LD began broadcasting on VHF channel 8, but the signal was nearly unusable due to interference from nearby stations WJLA-TV, WUSA, and WGAL. After a legal battle with Daystar over a lapsed construction permit, the station finally moved to channel 22 on May 22, 2015, adopting the call sign WMDO-CD.
In the 2016–17 FCC spectrum reallocation auction, WMDO-CD received $58,231,415 to vacate its frequency. To maintain its presence, the station entered into a channel-sharing agreement—a legal arrangement where two stations share a single digital frequency—first with WIAV-CD in 2017, and later with WDCO-CD in 2021.
After the agreement with WDCO-CD expired on December 31, 2021, the station went silent. It narrowly avoided license deletion under the Telecommunications Act of 1996 by returning to the air on December 29, 2022, via a sharing agreement with WWTD-LD. After a brief period of inactivity starting March 15, 2024, operations resumed on the WWTD-LD multiplex on June 27, 2024.

Frequently Asked Questions
Why did WMDO-CD change channels so many times?
The station moved frequently to accommodate the digital signal launches of larger stations (like WRC-TV and WNVT), to resolve signal interference issues, and as a result of FCC spectrum reallocations.
What is a channel-sharing agreement?
A channel-sharing agreement allows two separate broadcast stations to share a single 6 MHz digital channel, each maintaining its own distinct programming and identity on different subchannels.
Did the WMDO callsign come from Telemundo?
No. The callsign was derived from the station's co-ownership with WMDO radio (1540 AM) under Los Cerezos Television Co.
How much money did the station make from the FCC auction?
WMDO-CD received $58,231,415 during the FCC's 2016–17 spectrum reallocation auction in exchange for going off its own dedicated signal.
What happened to the station's programming during its silent periods?
During periods when the station had no authorized facilities, such as after the WDCO-CD agreement expired, UniMás programming was moved to a subchannel of WFDC-DT to maintain service.
