In 1948, WRGB took on secondary affiliations with the three other networks in operation (CBS, ABC, and DuMont). At the time of the announcement, the station only broadcast for 28 hours a week. On January 4, 1954, it moved from channel 4 to channel 6 to alleviate interference from WNBC-TV (then known as WRCA-TV) and Boston's WBZ-TV, and increased its radiated power approximately fourfold to 93,000 watts. WRGB dropped its secondary affiliations when WCDA (channel 41, now WTEN on channel 10) and WTRI (channel 35, now WNYT on channel 13) took the ABC and CBS affiliations respectively. From 1939 till 1957, the station's studio were located on Washington Avenue in downtown Schenectady. In 1957, WRGB moved to its current studio on Balltown Road on the line between Niskayuna and Schenectady; the old studio is currently occupied by Schenectady County Community College.
