![]() ![]() Other times, the requirements are more nuanced and political. Occasionally, we provide mass coverage, reaching large populations in a single country. However, we also work with clients who have more bespoke transmission requirements. MW (or AM) radio receivers are universal across the globe, meaning audiences need only the simplest of equipment to hear the content.ĭaily, we broadcast on medium wave into the Middle East from sites in Europe and Oman. The signal is transmitted better at night, so will provide a much wider coverage after dark. Encompass uses medium wave radio to deliver a combination of local, national and international radio services. Medium wave provides a higher quality of audio to the listener than shortwave, but over shorter distances. Every year, we even put on special broadcasts to reach expeditions in Antarctica – reaching anywhere else on the planet is easy by comparison! Ultimately, our goal is to provide the best listener experience possible, and we take pride in the fact that we can get clear, uninterrupted radio broadcasts into almost any part of the world. This ensures our clients maintain a strong signal strength using the best frequencies, delivering “loudest on the dial” results. Our Schedule and Frequency Management Team not only coordinates radio frequencies with international regulatory bodies but also selects the best global transmitter site to use for each region of the world. We work with some of the world’s best renowned international broadcasters to target ‘lifeline’ audiences, particularly in remote regions of the world where access to other forms of media is either unavailable or tightly controlled. ![]() Will surely want to keep up with beacon developments by reading the latestīeacon History.Encompass uses shortwave to deliver content to the millions of listeners around the world that use the most basic, inexpensive and widely available radio receivers. If you find the beacons useful, we hope you will support those who The FAROS program or Skimmer which posts information to the Reverse Beacon Network. Of when various beacons can be heard at your QTH, you will want to learn Have a computer and a computer-compatible radio and would like a record If you want to know where to point yourĪntenna or decide which beacons are the most interesting to you, you can Or use your computer and one of the Programs Which shows the currently transmitting beacons by frequency, Which beacon is transmitting at any particular time, one can either refer Signal may indicate a path with excellent propagation for stations using The beacons are running one hundred watts to a vertical, even a weak beacon Some beacons may be heard at too low a signal strength to catch the call.īecause the beacons transmit at known times, it is easy to know whichīeacon one is hearing without actually copying the CW callsign. Not every ham operator can copy calls at twenty-two words per minute and Of the various beacons to figure out where the band is open, but in practice, Or which band has the best propagation to a particular part of the world.Ĭan simply listen on the beacon frequencies and copy the CW callsigns International Beacon Network addresses the second of these possibilitiesīy insuring that reliable signals are always on the air, around the clock,įrom fixed locations worldwide." With three minutes of listeningįor the beacons, one can find out either where a particular band is open Wrote, "There are at least two possible explanations for an apparentlyĭead band: 1) propagation is poor, or 2) no one is transmitting. The new controller and radios will gradually replace the old equipment over the coming months. In 2015, a new controller design was implemented for use with new Icom IC-7200 radios. The transmitter used has been the Kenwood TS-50s for the past 20 years.Īnd is described in detail on the Beacon Controller page. The NCDXF/IARU International Beacon Network-Part 1 The NCDXF/IARU International Beacon Network-Part 2 The NCDXF/IARU International Beacon Network-Update These articles have a lot of interesting details about the background and history of the beacons. Three articles about the beacons appeared in QST and are reproduced by permission of the ARRL. TheĬurrent system of 18 beacons began operation in 1995 and has been in continuous Over the next few years the network was expanded slowly. So successful that the IARU proposed a world wide network of beacons operatingĢ4 hours a day. The first beacon began transmissions from Northern California in 1979 and was The entire system is designed, builtĪnd operated by volunteers at no cost except for the actual price of hardware Help both amateur and commercial high-frequency radio users assess theĬurrent condition of the ionosphere.
