History
KOPB-TV originally signed on the air as KOAP-TV, on February 6, 1961.[2] The call sign letters stood for "Oregon Agricultural Portland", preceded by the "K" prefix the Federal Communications Commission uses when assigning call signs for stations west of the Mississippi River.[3] It was a sattilite station for KOAC-TV in Corvallis, Oregon, whose call letters—carried over from KOAC-AM, which received them in the mid-1920s during its early years broadcasting as an AM radio station—stood for "Oregon Agricultural College" (Oregon State University's original name). KOAP-TV was first housed in a leased building at what is now known as 2828 SW Naito Parkway, with the transmitter being located on Council Crest.[3]
