In 1946 Henderson gave his daughter Thelma and her new husband George J. Volger the land and financial backing to start the radio station.

In 1946, through a special treaty coordinated between the licensing authorities of the United States and Canada, the frequency 860 kHz was assigned to Muscatine with the restrictions of a maximum power of 250 watts and operation only between the hours of sunrise to sunset.

Although KWPC did eventually receive permission to broadcast 24 hours a day (a provision added for national security reasons), the transmitter power output is not permitted to exceed 7 watts after sunset, and that is why the signal strength changes so noticeably at night.

Lee de Forest, the inventor of the “triode vacuum tube” and considered by many to be the “Father of American Radio,” was keynote speaker at the event.

Additional space was added to the back of the old farm house for the transmitter and the FM antenna bays were mounted at the top of the existing broadcast tower behind the building.

John was the son of well known Quad-City personality G. Laverne Flambo, who had been the executive director of Mid American Media which owned two Quad City radio stations.

“The Pirate FM,” as it became known, soon gained a devoted, fiercely loyal audience, as the station played lesser-known artists in a variety of genres... rock, jazz, blues and folk.

KFMH disc jockeys included Borderline Bob, Sean Tracy, Dirty Judy, John Obvious and Captain Steve.

In 1991 Flambo Broadcasting constructed a new and much taller tower in rural Wilton on which to relocate the KFMH antennas and increase the range of its signal.

The question was... “Would you be interested in purchasing Muscatine’s KWPC-AM radio station?” It was proposed that Flambo would sell KWPC, along with its buildings and property, while they retained ownership of KFMH and relocated those studios to Davenport.

John and Darlene Schwandke began operating KWPC on January 1, 1993 with renewed emphasis on local news and information.

Expanding the news department became a priority and included the addition of a state-of-the-art “mobile studio” which made it possible to provide instant remote broadcasting, even while driving, from anywhere within KWPC's coverage area.

The husband and wife team worked in partnership on a daily basis with John being responsible for sales, and programming and Darlene in charge of office management and accounting.

Muscatine Communications Inc. was considered a “family business” with son Warren active in advertising sales and the voice of John's mother being used on KWPC's daily sign-on and sign-off tapes.

Even though the operation studios are located in the Quad Cities, the frequency of 99.7 MHz remains licensed as a Muscatine radio station.

In March 2013, Steve Bridges launched 99 Plus KFMH as an internet station and picked up where it left off, playing rock, blues, and jazz.

KWCC is believed to be the first completely digital broadcasting facility to be built between Chicago and Denver, which was quite an achievement for a small town radio station.

W.P.W Broadcasting of Monmouth, Illinois, who already owned 15 radio stations along the Mississippi valley between Quincy and Dubuque, became the new owners of KWPC and KWCC on December 1, 1999.
