The FM signal has an effective radiated power (ERP) of 1,000 watts and covers the city of Nome and adjacent communities.
By day, it transmits with 25,000 watts and can be heard as far north as Barter Island and as far south as the Alaska Peninsula, with regular coverage of approximately 100,000 square miles (260,000 km2).
In addition to its local news, weather, public affairs and religious programming, KNOM broadcasts a wide range of music in various formats.
While serving at the Jesuit mission in the village of St. Mary's in 1959, Poole created a makeshift "radio station" by wiring 30 homes with speakers linked to the public address system.
After the Diocese of Fairbanks declared bankruptcy in February 2008, Busch (until his passing) and Schmidt worked toward incorporating the radio station as a non-profit entity independent of the Catholic Bishop of Northern Alaska.
In 2019, after an article from the Center of Investigative Reporting described Poole being allowed to retire at the Gonzaga campus after his abuse became publicly known,[6] KNOM's Board of Directors published a statement where they again renounce all of Poole's actions and commit to transparently carrying on with the mission of bringing news, inspiration, and encouragement to Western Alaska.
In the past, KNOM was operated primarily by volunteers who move to Nome and support the station in various ways as part of a year of service.
The station has also won 19 Gabriel awards, as well as honors from the Catholic Academy for Communication Arts Professionals (CACAP), the Alaska Broadcasters Association (ABA), and other organizations.
