But to minimize interference to other stations on 790 AM, KNST uses a directional antenna at all times and reduces its power to 500 watts at night.

Weekdays begin with a simulcast of KFYI's news and information show, The Conservative Circus with James T. Harris.

During the evening drive, The Afternoon Addiction with Garret Lewis can be heard both on this station and on KFYI in Phoenix.

Weekend shows focus on health, money, law and technology, some of which are paid brokered programming.

Syndicated weekend programs include Bill Handel on the Law, The Kim Komando Show, Sunday Nights with Bill Cunningham and an Arizona gardening and home repair show, Rosie Romero's Rosie On The House (originating from its flagship station KTAR-FM in Phoenix).

In the 1970s, 790 KCEE was a full service station, playing middle of the road music and airing NBC Radio News.

KNST was the radio flagship station for University of Arizona men's basketball and football play-by-play from about 1984 until 2004, when the broadcasts moved to all-sports KCUB, branded as "1290 The Source".
