KDHT-FM (107.1) was Denver’s Hot 107.1 and then Jack FM, from late 2009 to early 2014. If you went from hit radio to dance beats to a Jack FM playlist on the same dial position, you rode along with this station.

History

The KDHT calls took effect December 15, 2009, on the Bennett-licensed 107.1 facility, matching the “Hot 107.1” branding after KONN-FM. In March 2012 the station moved from rhythmic Top 40 into a dance-oriented format. Later that year, after a brief “Pot 107.1” stunt, it became an adult-hits station under the “Jack FM” brand. In March 2014 it flipped to alternative rock as “107X,” and three days later the call sign changed to KXDE.

This page covers only the 107.1 MHz era of KDHT. Other KDHT uses, on 92.5 and 95.7, have their own pages.

KONN-FM (107.1) was the Top 40 station on 107.1 FM in 2008 and 2009. If you were into hit radio in Denver then, you may remember it as “One FM” and then “Hot 107.1.”

History

After KSYY-FM flipped to Top 40 as “One FM” on February 7, 2008, the FCC call sign became KONN-FM on February 29. The station started with a rhythm-based hit-music sound and later moved toward a more mainstream Top 40 mix. In April 2009 the branding became “Hot 107.1,” and on December 15, 2009 the calls changed to KDHT-FM.

KSYY-FM (107.1) was “Sassy 107,” a soft adult contemporary station that moved toward Denver listeners in the mid-2000s. If you had a soft-rock office radio around 2006 and 2007, this may have been your station.

History

The call sign became KSYY-FM on March 20, 2006, as the station moved toward Denver-market service and went with a soft adult contemporary sound. In February 2008, it dropped that format and relaunched as a Top 40 station branded “One FM,” shortly before the calls changed to KONN-FM. The earlier call sign was KSIR-FM.

KSIR-FM (107.1) was the call sign on 107.1 FM from 1993 until 2006, the longest of the easy-listening years for the facility now known as KFCO. If you left an easy-listening station on in the 90s, you may have been parked here.

History

FCC call-sign history lists KSIR-FM starting April 26, 1993, following KSIR. The station stayed in its easy-listening era for much of this period. As the facility was repositioned toward the Denver market, the calls changed to KSYY-FM on March 20, 2006.

KSIR (107.1) was the call sign on 107.1 FM from 1991 to 1993, part of the long easy-listening stretch of the facility now known as KFCO. If you tuned in for easy listening east of Denver in the early 90s, you were listening to KSIR.

History

FCC records show the facility changed from KKDD to KSIR on July 1, 1991. It stayed in its easy-listening era until the call sign was adjusted to KSIR-FM in 1993.

KKDD (107.1) was the first call sign of the 107.1 FM facility east of Denver that is now KFCO. If you remember easy listening on 107.1 in the late 80s, this is where that story starts.

History

The facility signed on in 1985 as KKDD and was associated with easy-listening programming. FCC call-sign history shows KKDD stayed in use until 1991, when the calls changed to KSIR.

One facility, many call signs

FCC Facility ID 35023 later used the calls KSIR, KSIR-FM, KSYY-FM, KONN-FM, KDHT-FM, KXDE and KFCO. Each has its own page in the archive.

KDHT-FM (92.5) was a Denver-area FM station in the late 80s and early 90s that mixed folk, Americana and adult album alternative. If you liked your radio a little off the beaten path in that era, this was one to hunt for on the dial.

History

The 92.5 MHz facility had operated as KYOU. After a power increase and a move toward the Denver market, it took the KDHT calls on February 17, 1989. Under programmer Ira Gordon, KDHT built an early folk, Americana and AAA hybrid. In early 1993 the station was sold to Premiere Radio Networks, and 92.5 moved to a new-country format as KZDG, ending this KDHT era.

• KDHT: February 17, 1989 to early 1993
