Colorado net assigns idle AM to Triple A duty in Denver

By |

Colorado Public Radio has found a new use for the spare AM frequency that it couldn’t sell. OpenAir 1340 took to the air last month, bringing the Denver area a Triple A–format station featuring rock, folk and indie music ranging from the present day to rootsy influences. The station signed on Oct. 31 with the song “Colorado” by Denver band Paper Bird, an early indicator of OpenAir’s commitment to showcasing local music. CPR has already recorded more than a dozen local bands in its studios for broadcast on OpenAir.

AM: still used by several dozen pubcasters

AM radio uses the low frequencies where radio began, which have much longer wavelengths. While FM antennas are relatively small and mounted high on towers, AM’s longer wavelengths use the entire tower as an antenna, along with a network of underground wires that typically surround the tower in a circle as wide as the tower is high. Experts in the black art of AM facility design recommend that AM towers’ height be a precise fraction, such as one-quarter, of the station’s wavelength so that the tower will resonate with the frequency. Stations with lower frequencies tend to have higher towers. Old-timer KOAC in Corvallis, Ore.
