a shared-time arrangement, it could broadcast unlimited hours during the day but had to divide nighttime operations with Chicago's co-channel WBBM. KFAB was originally on the NBC Red Network. But it became a CBS Radio Network affiliate the week of January 5, 1932. Beginning in 1934, KFAB and WBBM synchronized their transmissions via a telephone line that ran from the WBBM transmitter outside Chicago to the KFAB site near Lincoln, thus allowing simultaneous nighttime operation and providing a nearly coast-to-coast CBS signal on their shared frequency. In March 1941, as part of the implementation of the North American Regional Broadcasting Agreement (NARBA), KFAB and WBBM were shifted to 780 kilocycles. Move to Omaha In 1944, KFAB moved to 1110 kHz, giving WBBM unlimited use of 780 kHz. WJAG in Norfolk, Nebraska was concerned that KFAB's operation on 1110 kHz would cause interference to its signal on 1090 kHz, so KFAB's owners paid the cost of moving WJAG to KFAB's former frequency of 780 kHz. KFAB relocated to Omaha as part of the frequency swap, originally with 10,000 watts, and switched to a directional nighttime pattern to limit interference to WBT in Charlotte, North Carolina. WBT had previously operated full time with a non-directional antenna, and, concurrent with KFAB's reassignment to 1110 kHz, implemented a nighttime directional pattern in order to jointly protect KFAB's signal, with both stations primarily directing their nighttime signals north–south. A few years after moving to Omaha KFAB increased its power to 50,000 watts. From its beginning KFAB has delivered a wide variety of programming, including news, weather, sports and farming reports. It became Nebraska's first 24-hour radio station in 1951. In the 1960s and 1970s, legendary newscaster Walt Kavanagh became famous for his school closing announcements during bad weather. The parents of nearly every school aged child in the area would listen intently as Kavanagh reported which districts were cancelled and which were not on snowy mornings. In 1948, while still an undergraduate at the University of Nebraska-Lincoln, Johnny Carson worked at KFAB writing and doing shows. In addition to Carson, KFAB was and continues to be the home of some of the state's most popular personalities, including Lyell "Mr. Football" Bremser, Ken Hedrick, John Coleman, Walt Kavanagh, "Texas" Mary, Gary Sadlemyer, Kent Pavelka and Jim Rose, most if not all have been inducted into the Nebraska Broadcasters Hall of Fame. .
