Amateur band beacon frequencies

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. The earliest record of radio propagation beacons goes back to World War II, when the German military operated propagation beacons on wavelengths of approximate 80 m and 10 m.

International Beacon Project Introduction

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.

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. Most beacons operate in continuous wave A1A and transmit their identification call sign and location. Some of them send long dashes to facilitate signal strength measurement.
