On February 27, 1971, both transmitter towers used by KOIN-FM and KOIN-TV—the main tower and the auxiliary tower—collapsed during an ice and wind storm. The two KOIN (AM) towers, located on the same property, were not damaged. Nine days later, on March 9, 1971, KOIN-FM and KOIN-TV returned to the air when a temporary tower was erected on the site of the collapsed auxiliary tower. During those nine days off the air, CBS programming was provided to the Portland market (and, by extension, most of Oregon) by independent station KVDO-TV in Salem (Oregon Public Broadcasting later purchased KVDO and moved the station to Bend as KOAB-TV). In 1978, a production company, MIRA Mobile Television, was founded.
