# KFNZ (AM)

KFNZ (610 kHz) is a commercial AM radio station licensed to Kansas City, Missouri. The Audacy, Inc.-owned station broadcasts a sports radio format. Its studios and offices are located on Squibb Road in Mission, Kansas. KFNZ is one of the oldest radio stations in the Kansas City metropolitan area, going on the air in 1922.
KFNZ is a Class B regional station, with a power of 5,000 watts, both the daytime and nighttime, using a non-directional antenna on one tower. The transmitter is off Mission Road in Prairie Village, Kansas. Programming is also heard on the HD2 channel of KFNZ-FM.
Local sports shows are heard from mornings to early evenings on weekdays, with programming from Fox Sports Radio airing nights and weekends. Although the station had the slogan "The Football Channel" when it began in June 2003, it is currently the flagship station of MLB's Kansas City Royals, whose rights were reacquired by Entercom (now Audacy) in 2008. It is also the co-flagship station of the NFL's Kansas City Chiefs. The Kansas State Wildcats radio network is also heard on KFNZ.

## History
### Early years (1922–1967)

Effective December 1, 1921, the Department of Commerce, which regulated radio at this time, adopted regulations setting aside two wavelengths for use by broadcasting stations: 360 meters (833 kHz) for "entertainment" programs, and 485 meters (619 kHz) for "market and weather" reports.
The station was first licensed on May 16, 1922, as WDAF, to the Kansas City Star, for operation on 360 meters. The WDAF call sign was randomly assigned from a sequential list of available call letters. Currently most stations west of the Mississippi River have call letters beginning with "K". However, WDAF was licensed before the government changed the dividing line between W and K call signs. Prior to the January 1923 establishment of the Mississippi River as the boundary, call letters beginning with "W" were generally assigned to stations east of an irregular line formed by the western state borders from North Dakota south to Texas, with calls beginning with "K" going only to stations in states west of that line.
WDAF made its debut broadcast on June 5, 1922. It bounced around various frequencies, including 750, 730, 680, 820 and 810 kHz. It moved to 610 kHz in 1928, splitting time with station WOQ, before becoming the sole occupant of 610 AM in Kansas City. WDAF became an NBC affiliate just before moving to 610 kHz. It carried programs from both the NBC Red Network and the Blue Network up until 1930, when WDAF became a primary NBC Red affiliate.
WDAF increased power to 5,000 watts daytime in 1935, and 5,000 watts nighttime in 1940. In 1949, co-owned television station WDAF-TV came on the air. It was the second TV station in Missouri and the first in Kansas City. Like WDAF (AM), it primarily was an NBC affiliate, although it carried shows from other networks as well. WDAF-TV became a Fox affiliate in 1994.
In 1958, the Kansas City Star sold WDAF-AM-TV to National Missouri TV. In 1960, National Missouri TV merged with Transcontinent Television. On March 5, 1961, Transcontinent signed on an FM station at 102.1 MHz, which today is KCKC. Taft Broadcasting merged with Transcontinent in 1965, bringing WDAF-AM-FM-TV under its control.

### Middle of the road music (1967–1977)

Taft changed 610 WDAF to a full service middle of the road music format on April 30, 1967. WDAF carried news from the ABC American Information Radio Network, mainly owing to the company's very good relationship with its television counterpart. It became a secondary CBS affiliate in 1974, airing programming such as the CBS Radio Mystery Theater.

### 61 Country (1977–2003)

WDAF flipped to country music in February 1977, calling itself "61 Country". Although Kansas City had several country stations, WDAF programmed its country music in an uptempo way, as if it were Top 40. Taft Broadcasting owned it until 1987, when a hostile takeover put it under Great American Communications ownership. After a financial restructuring, Great American sold WDAF-TV and became known as Citicasters, owning AM 610 and FM 102.1 until 1997.
Entercom bought WDAF (AM) in October 1997. The FM was sold off in June, first to American Radio Systems, then Westinghouse/CBS Radio. (It is currently owned by Steel City Media.) Despite having as many as three full power FM competitors at various times, WDAF remained the top-rated country station in Kansas City. From 1992 to 1995, WDAF also held the Royals broadcast rights. In 2002, the station picked up the rights to University of Missouri football and basketball. David Lawrence, Phil Young, and Ted Cramer were among the longtime personalities on 61 Country, along with newscasters Charles Gray, Frank Haynes, and Caroline Rooney.

### 610 Sports (2003–2024)

In 2003, Entercom announced it would move WDAF to 106.5 on the FM dial, and would flip AM 610 to sports talk to compete against WHB. Beginning August 10, 2003, the country programming was simulcast on both frequencies until the new sports station was ready. At 2 p.m. on September 10, 2003, the station became KCSP, "61 Sports" (later "610 Sports"). Leading up to the premiere, Entercom had swiped Jason Whitlock, Bill Maas and Tim Grunhard from WHB, though all three have since moved on. The Jim Rome Show moved to KCSP in December. Kansas Jayhawk sports moved to KCSP in September 2006. Kansas City Royals baseball began airing on KCSP in the 2008 season. In 2011, KCSP beat WHB in the ratings for the first time. In 2012, KCSP dropped The Jim Rome Show in favor of expanding its local programming.

### 96.5 The Fan (KFNZ-FM simulcast)

On August 8, 2024, at 10 a.m., KCSP announced that it would begin simulcasting on FM sister station KRBZ beginning August 15, and rebrand as "96.5 The Fan". The FM side, which adopted the KFNZ-FM callsign, would become the new flagship station for the Kansas City Chiefs (which had been on WDAF-FM) and the Royals with the move. Some Royals games would remain solely on 610 AM, which would also take on the KFNZ call sign.
