KPSZ's studios and offices are located on Locust Street in Des Moines along with Saga's other local stations (KRNT, KSTZ, KIOA, KOEZ and KAZR).
National religious leaders heard on KPSZ include Adrian Rogers, David Jeremiah, Joyce Meyer and Jim Daly.
Using a brokered programming model, hosts buy blocks of time on KPSZ and may use their shows to seek donations to their ministries.
It uses a directional antenna with a six-tower array to protect other stations on 940 AM, a Canadian and Mexican clear channel frequency.
This was a risky format in the post war era when network dramas, comedies, soap operas and game shows were very popular.
KIOA stayed competitive with the "big three" (WHO, KRNT, and KSO), in the Des Moines market and waged a spirited battle with its main competitor in the MOR format, KCBC.
In March the station moved its studios and offices out of the Onthank Building and into the old Tromar Ballroom at the corner of 5th and Park in downtown Des Moines.
KIOA tried to stay competitive, but with Stauffer Communications' KRNQ coming on air with a top 40 format as well, it was apparent that a change needed to be made soon.
KIOA fell to the middle of the pack as far as ratings went and some long term personalities left or took jobs off the air with the station.
In 1993, the station was purchased by Saga Communications and moved to its present location at 1416 Locust Street in downtown Des Moines.
[7] The station never took off, and in February 1999, it went back to simulcasting KIOA except for the morning drive time, which featured Don Imus, syndicated from New York City.
"The Big Ticket" carried Sporting News Radio network programs, local talk shows with personalities such as Larry Morgan and Steve Deace, and I-Cubs, Drake Bulldogs, and Nebraska Cornhuskers games.
In its early years, KPSZ had a block of locally programmed Christian music from 3-7 p.m. weekdays, hosted by Doug Griffin.
On weekend, KPSZ airs Don Thompson's "Music and Memories," as well as "That Good Ole Gospel Sound".
Late nights, KPSZ carries programming from Singing News Radio, a Southern gospel music and talk network.
