KMHD (89.1 FM) is a listener-supported, non-profit FM broadcast radio station located in the Portland, Oregon area. For the first twenty-five years of its operation, the station's studio was located on the Mt. Hood Community College campus in Gresham, Oregon, and the transmitter is located atop Portland's Tualatin Mountains. In addition to its broadcast signal at 89.1, KMHD also simulcasts locally on an HD channel, as well as through streaming audio on the station's website. KMHD's main programming is also carried on OPB-FM subchannel HD3 and on SAP audio channel 3 of OPB-TV digital subchannel 3.[2]

KMHD is among the oldest listener-supported Jazz radio stations in the United States.[citation needed]

Although owned by Mt. Hood Community College, the station has never been a part of the college's radio broadcasting educational program.


The station has been providing the Portland, Oregon community with jazz and blues since 1984, utilizing volunteer announcers - many of them prominent local musicians or broadcasters - almost entirely since its inception.[3]

In March 2009, the Mt. Hood Community College District Board of Education agreed to transfer of the station's programming, operational and fundraising responsibilities to Oregon Public Broadcasting.[4] The agreement was a response to a cut in state support. The transfer was approved by the board of education in mid-May and took effect on August 10, 2009, at 2:00 p.m.[5] Although the station's programming now originates from OPB's Portland studios, the station continues to use the same call letters and broadcast frequency, and continues to be owned by Mt. Hood Community College.

KMHD-HD2 (branded as "KMHD2") aired a college radio format, including blocks of hip hop, rock, metal, world, and indie music. After local radio station KZME ceased broadcasting on 91.5, KMHD began carrying them on their HD2 digital radio subchannel. KMHD-HD2 is not carried by OPB's FM or TV audio subchannels.[6]
