KLTH (106.7 FM, "The Eagle") is a classic hits formatted radio station located in the Portland, Oregon, area and broadcasts at 106.7 FM. KLTH's studios are located in Tigard, Oregon and its transmitter is located in Portland's west hills. It is currently under ownership of iHeartMedia, Inc..
KQIV (also KQ4 and FM107) was a short-lived but popular progressive rock FM radio station in Lake Oswego, Oregon, that operated on 106.7 MHz. The station was owned and operated by Willamette Broadcasting Company, Inc. (Walter J. M. Kraus, President) and signed on at 10:15 P.M. PDT on September 15, 1972.
The original KQIV offices and studios were located at the Lake Oswego Elks Lodge (#2263). Members of this historically conservative organization frequently crossed paths with the station's hippie disc jockeys and creative people.
The KQIV transmitter was located at Outlook, between Oregon City and Carver. An American Electronic Laboratories (AEL) FM-25KD transmitter fed 24 kW into a Jampro JSCP eight element antenna yielding an ERP of 100 kW. The antenna was mounted on a 200-foot tower based at an elevation of 800 feet.
Both the "Q" and "IV" in the station's call sign alluded to four-channel quadraphonic sound. Although KQIV was widely reported in the local press to be the second quadraphonic broadcast station in the world and the first to be designed and built to be quadraphonic, those reports were based on erroneous information. KQIV established its quadraphonic identity and "Rockin' in Quad" branding on its anticipation of being selected as the exclusive FM station in the Portland radio market to field test the Dorren Quadraplex System, invented by audio engineer Louis Dorren. About a month before KQIV went on the air, the FCC suspended further testing of Quadraplex due to a concern that the system used a subcarrier component not permitted under its regulations.
KQIV continued to identify itself as a quadraphonic station in the hope that Quadraplex testing eventually would be permitted. Meanwhile, the station broadcast music from phonograph records encoded in various quadraphonic matrix formats.
In 1974, operation of KQIV was turned over to Brotherhood Broadcasting Company (Roy Jay, President) which changed the station's music format to urban contemporary, branded as Soul 107. In 1975, the KQIV offices and studios were moved to Milwaukie. Ongoing financial difficulties led to the court-ordered liquidation of KQIV, which went off the air on June 18, 1976.
Following the demise of KQIV, 106.7 MHz remained silent in the Portland area for nearly 14 months. On August 1, 1977, Communico Northwest Corp. began operating KMJK (Magic 107) on the frequency with studios at "Magic Manor" in Lake Oswego and its transmitter in Portland. KLTH uses the same license as KQIV. On June 29, 1979 KMJK changed their format to top 40 (as "Magic 107"). In July 1981, KMJK changed their format back to soft AC (as "Magic 107"). In August 1982, KMJK changed their format again to top 40 (as "Magic 107"). On April 13, 1987 at 6 AM, KMJK changed their format to classic hits (as "Classic Hits 106.7"). On September 1, 1989 KMJK shifted its format to classic rock (as "Classic Rock 106.7"). On February 19, 1990 KMJK changed their format to hot adult contemporary (as "106.7 Magic FM").
On January 25, 1991 KMJK changed their call letters to KMXI and rebranded as "Mix 106". On December 30, 1991 KMXI changed their format to oldies as "Oldies 106.7".
On July 7, 1993 KMXI changed their call letters to KKBK and changed their format to classical (as "K-Bach").
On March 17, 1994 KKBK changed their call letters to KKJZ and changed their format to smooth jazz as "Smooth Jazz 106.7".
On February 1, 2002, KKJZ changed their call letters to KLTH and changed their format to adult contemporary as "Lite Rock 106.7, K-Lite". On January 9, 2006, KLTH changed their format to 1960s and 1970s oldies as "106.7 K-Hits." Although most of the songs played on the station does cover the 1960s and 1970s (of which makes up a majority of its library), they also expanded its scope to cover the 1980s as well, given its competition being Adult Hits KYCH, which was the previous outlet for the Oldies format prior to KLTH's debut. Specialty programs on KLTH include "Saturday Night Fever", a weekly classic Disco shows and Casey Kasem's "American Top 40: The 70s" on Sunday mornings.
KLTH was sold to Clear Channel Communications along with KXJM on April 1, 2009 from CBS Radio. KLTH co-existed with sister classic hits KQOL, who Clear Channel had operated prior to the transaction. Both stations co-existed until May 6, 2009, when Clear Channel switched KQOL to Classic Rock, moving many of the KQOL listeners over to its KLTH, saying "Welcome 105.9 listeners."
Shortly after the move, on August 17, 2009, the name was changed to "Oldies 106.7" with a logo identical to CBS Radio's WODS in Boston, but since 2010, it has been replaced by a more modern logo. In the May 2011 Arbitron PPMs, KLTH became the number one station in the Portland area radio rankings, overtaking sister station KKCW.
On August 1, 2014 at 5 PM, KLTH shifted their format to classic hits and rebranded as "106.7 The Eagle".
