List Of 50 Kw Am Radio Stations In The United States

List Of 50 Kw Am Radio Stations In The United States – The Georgia Farm Radio Network (GFRN) is the state’s largest, longest-running agricultural radio network featuring Georgia agriculture and farming news, opinion, market and product information. We offer seven radio programs every weekday, which are broadcast on over 70 radio stations across the country.

We’ve been doing this since 1965, so we know the agriculture industry in Georgia. We’re part of the Georgia Farm Bureau, the state’s largest agricultural agency, which means we’re at the heart of the industry.

All programs on the Georgia Farm Radio Network are hosted by GFRN News Director John Holcomb or Damon Jones.

GFRN’s first news program focuses on the multi-billion dollar agriculture industry. GFRN Ag News has the latest commodity news, market trends and USDA news. We cover the news that matters to the nation’s agriculture industry, from the nation’s capital to Atlanta’s Gold Dome to the latest news straight from the field.

Daily information covering various types of Georgian agriculture. At the show, students will read data and other interesting facts about Georgia’s number one industry.

John Holcomb, the newest member of the GFRN family, joined the network in 2017. John was born and raised in Rocky Face, Georgia where he grew up on a small family cattle ranch. John is a graduate of the University of Georgia, where he majored in digital journalism and advertising. In his spare time, he enjoys kayaking, road biking, spending time with friends and family, and watching the Dawgs “like in the yard.”

Damon Jones joined our staff in 2011. Damon was sports director at WGXA-TV when he joined the staff of GFRN and the Georgia Farm Monitor. He learned a lot about Georgia farmers and the state’s agriculture during his travels, producing stories for radio and television.

Our partnership between the Georgia Bureau of Agriculture and the Georgia Open Channel News Network provides us with resources, veteran broadcast talent and presentation quality that is second to none in the business.

We deliver reliable daily agribusiness news to your station that your community can use from journalists you know and trust. Georgia Farm Bureau has been in farm radio broadcasting since 1965! Ask your local Office insurance agent about co-op financing opportunities. Medium wave (MW) is part of the medium frequency (MF) radio band used primarily for AM radio broadcasting. The spectrum provides approximately 120 channels with lower sound quality than FM stations in the FM broadcast band. During the day, reception is limited to a few local stations, although this depends on signal conditions and the quality of the radio receiver used. Better signal propagation at night allows signal reception over greater distances (within a range of about 2,000 km or 1,200 miles). This can lead to increased interference as many channels have multiple transmitters operating simultaneously around the world. Also, amplitude modulation (AM) is often more affected by various electronic devices, especially power devices and computers. Powerful transmitters cover larger areas than in the FM broadcast band, but require more power and longer antennas. Digital means are possible, but they have not yet reached the mother.

From the 1920s to the 1950s, MW was the dominant radio band in broadcasting until FM, with better sound quality, took over. In Europe, digital radio is becoming more popular and gives AM stations the ability to switch if a frequency is not available in the FM band (however, digital radio still has broadcast problems in many parts of Europe). Since the 2010s, many European countries have disabled or reduced their MW tariffs.

The term is historical, dating back to the early 20th century, when the radio spectrum was divided into long-wave (LW), medium-wave and short-wave (SW) radio bands based on wavelength.

In Europe, Africa and Asia, the MW band has 120 channels with carrier frequencies from 531 to 1602 kHz, spaced every 9 kHz. Frequency coordination avoids the use of adjacent channels in an area. The entire allocated spectrum, including modulated audio, is between 526.5 and 1606.5 kHz.

And 10 kHz channels. The maximum of 1610 kHz is used only by low power stations; this is the preferred domain for automated traffic, weather and tourist information services.

Because the sound spectrum is transmitted twice on both bands. This is fine for talk and news, but not for high fidelity music. However, most stations use an audio bandwidth of 10 kHz, which is not hi-fi, but enough to be listed frequently. Most stations in the UK use the 6.3 kHz bandwidth.

In the case of AM, it depends largely on the frequency filters of each receiver, how the sound is produced. This is a big disadvantage compared to FM and digital modes, where the reduced volume is more objective. Increased audio bandwidth causes interference on adjacent channels.

The wavelength in this band is sufficient for radio waves not to be blocked by buildings and hills, and to follow the curve of the Earth and spread beyond the horizon; this is called a ground wave. Practical ground wave reception for powerful transmitters is typically 200 to 300 miles, with longer distances in highly conductive soil and longer distances in salt water. The ground wave continues to reach low frequencies of medium waves.

Medium waves are also reflected from layers of charged particles in the ionosphere and can return to Earth over greater distances; this is called a space wave. At night, especially during the winter months and during low solar activity, the D layer of the lower ionosphere disappears completely. When this happens, MW radio signals can easily be received hundreds or thousands of miles away because the signal is reflected by the high F layer. This allows for very long distance broadcasting, but it can also interfere with remote local stations. Because of the limited number of channels available in the MW broadcast band, the same frequency is retransmitted to different broadcast stations hundreds of miles apart. In the evening of good weather propagation, the weather signals of the remote station may interfere with the signals of local stations on that circuit. In North America, the North American Regional Broadcasting Agreement (NARBA) allocates certain channels for nighttime use in areas of extended air service by a few specially licensed AM broadcast stations. These channels are called pure channels and must be declared with a maximum power of 10-50 kW.

Initially, broadcasting in the United States was limited to two wavelengths: “tertainmt” was broadcast on 360 meters (833 kHz), and stations had to switch to 485 meters (619 kHz), which broadcast weather forecasts, crop price reports , and other governments. report. .

This arrangement had many practical problems. Early transmitters were technically dirty and virtually impossible to precisely synchronize their intended frequencies, and if (as was often the case) two (or more) stations in the same part of the country were broadcasting at the same time, the resulting interference meant that. normally nor could it be received to hear clearly. The Commerce Department rarely intervened in such cases, but left it up to stations to enter into voluntary time-sharing agreements among themselves. Adding the third length of the “tertainmt”, 400 meters,

In 1923, the Department of Commerce realized that as more and more stations applied for commercial licenses, it was not feasible to broadcast all stations on the same three-wave length. On May 15, 1923, Secretary of Commerce Herbert Hoover announced a new band plan that allocated 81 frequencies, in 10 kHz increments, from 550 kHz to 1350 kHz (expanded to 1500, 1600, and finally 1700 kHz). Each station would be assigned a frequency (although usually shared with stations in other parts of the country and/or abroad), so it would no longer have to broadcast weather and government reports on more tertainmt frequencies. Class A and B stations were divided into sub-bands.

In the United States and Canada, the maximum transmission power is limited to 50 kilowatts, while in Europe there are medium wave stations with daytime transmission power up to 2 megawatts.

The Federal Communications Commission (FCC) requires most AM radio stations in the United States to turn off at night, reduce power, or use a directional antenna array to avoid interference at night, only in long-distance air—due to propagation. (sometimes referred to as ‘jump’). Stations that close completely at night are often called “day stations”. Similar regulations apply to Canadian facilities operated by Industry Canada; However, daytime timers no longer exist in Canada, with the last station leaving in 2013 after moving to the FM band.

Many countries have shut down many MW generators due to cost reduction and low MW inventory usage. These include Germany,

Large toll networks remain in the UK, Spain, Romania and Italy. In the Netherlands and Scandinavia, some of the new, well-run stations started low-power services on old high-power frequencies. This also applies to former coastal pioneer Radio Caroline, which now holds the 648kHz license used by the BBC World Service for decades. As the MW band decreases,
