It cannot be Class D because the, If the available classes are B and D, then the Domestic Class will be Class B. As early as the 1930s, debate raged in Washington, D.C., and in the U.S. broadcasting industry over whether continuation of the clear-channel system was justifiable. WQIK-FM is unusual in the radio industry as a station that has kept its original call sign and format for more than half a century. That proposal was finally taken off the FCC's docket in the late 1970s. While Cumulus owns three sports stations in Oklahoma City, 98.1 WWLS-FM and AM 930 WKY have mostly local shows on weekdays while 640 KWPN carries mostly syndicated programming from ESPN Radio. [5], One station, KOB in Albuquerque, New Mexico, fought a long legal battle against the Federal Communications Commission (FCC) and New York's WABC for the right to move from a regional channel to a clear channel, 770 kHz, arguing that the New York signal was so weak in the mountain west that it served no one. Nearly all these stations in the United States, Canada and The Bahamas broadcast at 50,000 watts, with several clear-channel stations in Mexico going as high as 150,000 watts and XEW in Mexico City operating at 250,000 watts for over 80 years. The rules adopted in MM Docket 87-267 allow existing unlimited-time Class B (formerly Class II and III) stations to voluntarily reclassify their. Classes "I-A" and "I-B" still mandate a minimum efficiency of 362.10 mV/m/kW at 1 km, whereas Class "I-N" is permitted to use the lower Class B minimum efficiency of 281.63 mV/m/kW at 1 km. Now that the Clear Channel has gone private, the company wasted little time in identifying 55 radio stations to sell. [citation needed]. The AM band frequencies are divided into three categories: Clear, Regional, and Local channels. Downgraded to class B in 2011 to make room for co-channel sister station. Clear-channel stations, unlike all other AM stations in North America, have a secondary service area; that is, they are entitled to protection from interference to their nighttime skywave signals. Once the construction permit becomes licensed as Class D, then any licensed daytime record will be changed to Class D also. Its studios are located along the West Loop Freeway (I-610) in the city's Uptown district. They are: The Domestic Class (or class of the station with NARBA set aside 37 Class I-A frequencies and 27 Class I-B frequencies. WVLN 740 AM is a radio station broadcasting a sports talk format. Gradually maximum power was increased to 50,000 watts: additionally there were some short-lived experiments with 250–500 kilowatt "super-power" operations. These were for the most part Class I-A. (Western clear channels, such as 680 in San Francisco, had been "duplicated" in the eastern states for many years.) Some of the original NARBA signatories, including the United States, Canada and Mexico, have implemented bilateral agreements that supersede NARBA's terms, eliminating among other things the distinction between the two kinds of clear channel: the original "I-A" and "I-B" classes, and the newer, U.S.-only "I-N" class, which are now all included in class A. When two figures are listed, the first is daytime power, the second is nighttime. WWWE is co-owned with WAEC in Atlanta, Georgia. The system exists to ensure the viability of cross-country or cross-continent radio service, and is enforced through a series of treaties and statutory laws. Radio fans (and staff at those stations) often affectionately call such stations "flamethrowers" or "blowtorches" because of their high power, and boast about their reach by a combined state and provincial count of their coverage area. KFNN (1510 kHz) is a commercial business news formatted radio station licensed to Mesa, Arizona, broadcasting from studios located in North Scottsdale, Arizona, on 1510 AM, and simulcast on 105.3 FM. In 1987 the FCC changed its rules to prohibit applications for new "class-D" stations. Mr. Roe was the original licensee and died in 1984. The system exists to ensure the viability of cross-country or cross-continent radio service, and is enforced through a series of treaties and statutory laws. The licensees of clear-channel stations argued that, without their special status, many rural areas would receive no radio service at all. There were 61 daytimers in Mexico in 2015.[8]. Owned by Golden West Broadcasting, it broadcasts a Christian format. It is a non-commercial, listener-supported radio station owned and operated by the Montrose Broadcasting Corporation, a non-profit organization founded by W. Douglas Roe. These classes are A, B, C, and D. Generally, all U.S. records will have both a Domestic Class and a Region 2 Class. Classes of AM stations are defined as follows: If you don't want to use the easy way to determine the station's domestic class (via the AM Query), here's the steps to follow to determine the class. Some of these stations are what was once known as the "clear channel" stations; others are not. WMAC is a commercial Class B AM radio station in Macon, Georgia. Daytimers (also known as daytime-only stations) are AM radio stations that are limited to broadcasting during the daytime only, as their signals would interfere with clear-channel and other radio stations at night, when solar radiation is reduced, and medium wave radio signals can propagate much farther. The following two tables show all of the class-A stations in North America. There exist exceptions, where a former Class B station was elevated to Class A, yet it maintained its previous antenna system, or made only minor changes thereto. In October 1941 the FCC's engineering department presented a report on a complete reorganization of the clear-channel service; the report considered the possibility of "some 25 superpower stations of 500,000 watts or more, strategically located to provide maximum service" (as Broadcasting described it), and suggested that stations would have to be relocated away from the east and west coasts in such a scenario, as coastal stations waste energy over the oceans. Such stations are allowed three manners of operation after sunset; to sign off the air completely until sunrise, reduce power (sometimes dramatically, to only a few watts), or switch to a nighttime-only frequency (such as the Detroit area's WNZK, which broadcasts on 690 during the day, and on 680 at night). There are two fields in the CDBS database and the AM Query search results that involve the class of station. We found 58 FM radio stations and 40 AM radio stations in the Clearwater, FL area. Another group of stations, formerly known as class II stations, were licensed to operate on the former "I-B" clear channels with significant power at night, provided that they use directional antenna systems to minimize radiation towards the primary stations. The system exists to ensure the viability of cross-country or cross-continent radio service, and is enforced through a series of treaties and statutory laws.
