- KOPB-TV abstract "KOPB-TV is a public television station serving the Portland, Oregon television market. It is owned and operated by Oregon Public Broadcasting. It broadcasts its digital signal on VHF channel 10.KOPB-TV originally signed on the air as KOAP-TV, on February 6, 1961. The call sign letters stood for "Oregon Air Portland", preceded by the K prefix the Federal Communications Commission uses when assigning call signs for stations west of the Mississippi River. It was a sister station to 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 Air Corvallis". KOAP was first housed at the campus of Portland State College, with the transmitter being located on Council Crest. KOAP-TV was a member of NET, or National Educational Television, carrying its programs. On April 30, 1962, KOAP-TV's FM sister service (KOAP-FM) signed on the air. By 1966, most local programs originated at KOAP-TV.Originally known on-air as OEB (Oregon Educational Broadcasting), the organization running the station changed its name in early 1972 to OEPBS (Oregon Educational & Public Broadcasting Service). The network was spun off from the state board of education in October 1981 and renamed Oregon Public Broadcasting. At the same time, the network moved to Portland, and KOAP-FM/TV became the flagship stations. On February 15, 1989, KOAP changed their call letters to KOPB, for both radio and television.OPB was a pioneer in HDTV. As early as March 5, 1997, OPB's experimental HDTV station transmitted a random-bit data stream. On September 15, 1997, OPB Portland was assigned the experimental call letters KAXC for channel 35. Then on October 11, 1997, at 4:37 p.m. KAXC became the first TV station in Oregon and one of the first on the west coast to transmit an HDTV picture. After experimentation ended, channel 35 was vacated. On December 7, 2001 KOPB-DT began operation on channel 27.".
