 Stations broadcasting on channels 52 to 69 were required to vacate those channels by December 31, 2011, and all analog television transmitters (primarily low-powered (LP), and Class-A low-powered (-CA) stations, and also broadcast translator (TX) repeaters in rural communities) were required to shut down by September 1, 2015.On April 24, 2015, it was announced that the conversion date for standard LPTVs and translators still broadcasting in analog had been suspended until further notice, due to economic problems that might have arisen from the then-upcoming spectrum auction; however, Class A low-powered stations were still required to convert by the original deadline date of September 1, 2015.After the auction's completion in 2017, the FCC announced on May 17 of that year that all analog low-power stations and transmitters must convert by July 13, 2021.
