That same year, the call letters were changed again to the current WTEN when the station moved to VHF channel 10. By this time, the market had expanded to cover not only east-central New York, but also large swaths of southwestern Vermont and western Massachusetts. Not only is this market one of the largest east of the Mississippi River, but much of it is very mountainous. UHF stations have never covered large areas or rugged terrain very well. When the FCC allocated two additional VHF channels to Albany, Hudson Valley sought and received permission to move to channel 10.
