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.
A radio propagation beacon is a radio beacon , which is mainly used for investigating the propagation of radio signals. Currently most radio propagation beacons use amateur radio frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and receivers.
