Licensed to Idaho Falls, Idaho, United States, the station is currently owned by Sand Hill Media Corp and features programming from Jones Radio Networks.

[3] KGVM-FM was owned by Golden Valley FM, Inc., until 1975, when the Federal Communications Commission approved after two years of delays a sale to Idaho Broadcasters, Inc.

The call letters were changed to KUPI-FM, which would hold for most of the next 36 years, except for between 1979 and 1988, when the station was KQPI-FM instead.

In 2011, a large frequency shuffle involving dozens of stations swept the Mountain West.

To keep the KUPI-FM country programming on 99.1, KSNA was relocated from one license at 94.3 to the other at 100.7, and the two stations also switched call signs; at the same time, KSNA shifted from CHR to adult CHR.
