Amateur band beacon frequencies

For example, the 4U1UN beacon in New York is currently off air while renovation work is being completed to the roof of the United Nations building where it is housed. Each beacon transmits in turn — a second sequence every three minutes. Once they have sent their sequence on, say, 14 MHz, the beacon moves up to 18 MHz and repeats it and another beacon takes up their slot on 14 MHz. All you have to do is just listen on the beacon frequencies and copy the CW callsigns of the various beacons to figure out where the band is open to. Because the beacons transmit at known times, it is easy to know which beacon is transmitting without actually knowing Morse code. The beacons starts to transmit at W, before stepping down to 10W, 1W and mW in one-second steps. You may be surprised but it is very easy to hear some of the beacons transmitting at mW — which is 1, th the full power of Watts!

Beacon Update

An amateur radio propagation beacon is a radio beacon , whose purpose is the investigation of the propagation of radio signals. Most radio propagation beacons use amateur radio frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and receivers.

These beacons help both amateur and commercial high-frequency radio users assess the current condition of the ionosphere. The entire system is designed, built and operated by volunteers at no cost except for the actual price of hardware components, shipping costs, and so on. The first beacon began transmissions from Northern California in and was so successful that the IARU proposed a world wide network of beacons operating 24 hours a day. Over the next few years the network was expanded slowly. The current system of 18 beacons began operation in and has been in continuous operation ever since.
