WPTT (1540 kHz, "92.9 FM") is a commercial AM radio station in Hartford, Wisconsin, serving the Greater Milwaukee radio market. It airs an adult hits radio format and is owned by Tomsun Media LLC, which is operated by David and Connie Stout. The radio studios are on North Main Street at Summer Street in Hartford.

WPTT is a daytimer station. Its transmitter is co-located with WTKM-FM's tower, on West Waterford Road. WPTT is powered at 500 watts using a non-directional antenna but must go off the air at night to avoid interference. AM 1540 is a clear channel frequency, reserved for Class A stations KXEL in Waterloo, Iowa, and ZNS-1 in Nassau, Bahamas. Programming on WPTT is heard around the clock on 200-watt FM translator W225CP at 92.9 MHz.

The station signed on the air in 1951; 73 years ago (1951). Its original call sign was WTKM. In 1973, it added a sister station, WTKM-FM at 104.9 MHz. Both stations played polka music with other full service radio features of news, weather, talk and local high school sports. Greater Milwaukee has a number of residents who trace their history to Poland and other Eastern European countries where polka music is popular.

Most of WTKM's programming was simulcast on both the AM and FM stations. However, on Sundays afternoons, the AM station aired separate German Language and music programming called "The Voice Of Germany." Each weekday afternoon, for Catholic listeners, the station recited "The Holy Rosary".

On December 1, 2009, WTKM 1540 separated its programming from WTKM-FM 104.9. The AM station launched an oldies format, as "Cruisin' 1540". Cruisin' played hits from the 1950s, 60s and 70s, including The Beatles, The Beach Boys, Motown and more.

In 2017, a Sunday afternoon polka music show was added that had been airing on sister station WTKM-FM. Cruisin 1540 also kept many of its full service elements of news, weather, talk and high school sports.

On September 1, 2017 at 1 p.m., WTKM signed on an FM translator at 92.9 FM. The AM station changed its call sign to WPTT, and flipped to an adult hits format leaning towards upbeat songs as "Party 92.9". Key artists include Madonna, Michael Jackson and Lady Gaga. 92.9 W225CP has been approved by the FCC to move their antenna and change the city of license to Milwaukee as of 5/24/24.

WPTT broadcasts on an FM translator owned by Tomsun Media, LLC.
