KISU-FM COVERAGE MAPS
Pocatello & Vicinity
91.1
The real coverage of KISU's 91.1 transmitter allows a traveler in a car to listen to this frequency almost all the way to Dubois going north on I-15, but the signal trails off if traveling east of I-15. To the west, motorists can hear KISU quite well all the way to Arco, and west on the interstate to just east of the Rupert area where another station finally interferes. The map is fairly accurate in reflecting coverage to the south, although a car radio will draw in the signal to Downey and going up the Malad hill. Low geographical areas are a problem to the south. Going east, the map is fairly accurate, as the mountains restrict signal extension.
Idaho Falls & Vicinity
91.3
The real coverage of KISU's Idaho Falls translator is far different than the map indicates. Coverage is pretty good north to Rigby, and actually about 20 miles to the west towards the INL site. To the south this frequency is easily acquired on a car radio to about 10 miles south of Blackfoot. The map showing coverage to the east is fairly accurate.
