Amateur radio beacons
Beacons are specially constructed amateur radio stations whose sole purpose is to transmit a predefined signal at a specific time on a specific frequency. A special type of beacon called a time beacon broadcasts the time. Operating frequencies are The purpose of the beacons is two-fold; to provide reliable, frequency-stable reference points, and to assist commercial and amateur operators in assessing propagation conditions. The system was designed and built by volunteers and continues to be operated by a group of volunteers.

Radio beacon - Wikipedia
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.
Sveta Bilyalova. Age: 30. A young, loving beauty with a flexible body and a delightful smile offers an unforgettable meeting with the most vivid impressions.
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.
In navigation , a radio beacon rarely electromagnetic beacon is a kind of beacon , a device that marks a fixed location and allows direction-finding equipment to find relative bearing. Radio beacons transmit a radio signal that is picked up by radio direction-finding systems on ships, aircraft and vehicles to determine the direction to the beacon. A radio beacon is a transmitter at a known location and transmits a continuous or periodic radio signal with limited information for example, its identification or location on a specified radio frequency.
