Starting with this issue is a snapshot in time (1985). AM was still KING in Wyoming but FM was coming on.  In the 90s broadcasting became a commodity with stations changing ownerships regularly. Callsigns also changed so remember, this report uses what was in effect in 1985.

Pre-WW2 stations were few and a breed apart.

1. - 1930 [KSPR] Became KTWO in Casper, when combined with TV ownership in 1959 only to be split again. Original callsign was in KD sequence [as in KDKA Pittsburg], but replaced by owner selected KSPR. Noteable was news director Pete Williams.  After starting as Wyoming legislative reporter, his career would lead to Assistant Secretary of Defense for Public Affairs for then  Assistant Secretary of Defense Dick Cheney during the first Gulf War and currently is the Supreme Court correspondent for NBC Washington Bureau. He followed a path set earlier by KTWO legislative reporter Steve Cook in the 70's, who left to become press secrtary for Rep Teno Roncalio. Steve is now VP for Public Relations, National Association of Realtors. Between them was KTWO legislative reporter Phil Nobel, who put KLEN FM on the air in Cheyenne in September 1983. Other fixtures at KTWO were Jack Rosenthal and Bob Dallas Price who is still seen around the station. At 50 KW Clear Channel KTWO served much of the state in daytime and at night covered the western United States.

2. - 1934 KWYO in Sheridan, starting in Bob Carroll's furniture shop. In 1985 ownership included Sen. Malcom Wallop.

3. - 1938 [KVRS] KRKK in Rock Springs

4. - 1940 KFBC in Cheyenne, part owner Larry Birieffi announced University of Wyoming sports from 1947 to 1986.

5. - 1941 KPOW in Powell, chief engineer William McManus saw a lot of service in western Wyoming including Jackson FM stations. For fifty years a feature on KPOW was the cowboy songs of Roy Barnes, died 2004.

After WW2 a number of stations started up, mostly low power community service allocations.
