KADO-CD
KADO-CD is a low-power Class A family and religious television station in Shreveport, Louisiana, broadcasting locally on UHF channel 40.
While KADO had voluntarily applied to the Federal Communications Commission for digital channel UHF 40, the station's management estimated the cost of digital transition to be between $150,000 and a quarter-million dollars, a prohibitive cost for a small low-power broadcaster. The station was licensed for digital operation on June 3, 2015.
