The Synchronized Beacon Project (SBP) is an effort to deploy coordinated beacon transmitters on 50 MHz using a one-minute transmitting sequence of PI4, CW, and unmodulated carrier. Since modern beacon transmitters are multi-mode and frequency-agile, beacons that normally transmit on other time-multiplexed modes such as WSPR can take part in the ...
The network operated on 14.1 MHz and the beacon format remained unchanged. [3] In 1995, work began to improve the existing beacon network, so it could operate on 5 designated frequencies on the high frequency band. The new beacon network used Kenwood TS-50 transceivers keyed and controlled by an upgraded beacon controller unit.
These beacons transmit only their single-letter identifier in standard CW (A1A) using Morse code. The following call signs and frequencies of cluster beacons were reported between September 2007 and November 2008 in the Numbers&Oddities newsletter, [ 8 ] Utility DX Forum [ 9 ] and ENIGMA-2000: [ 10 ]
Because the propagation on 10 meters can vary drastically throughout the day, propagation beacons are very important to gauge the current conditions of the band. With some differences in each ITU Regions and also from country to country, the beacon sub-bands fall between 28.100–28.300 MHz. ITU Region 1 is generally 28.190-28.225 MHz and ITU ...
9A5ADI has established a QRPp (very low power) CW Beacon 9A5ADI/B on 5288.8 kHz running 100 mW into a 15 m long wire. It is located in Vinkovci (JN95jg). The transmission sequence is as follows - 10 seconds tone, v v v, callsign, power, locator, room temperature and pressure.

Signalling by keying the carrier directly, a.k.a. continuous wave (CW) or on–off keying, currently used in amateur radio. This is often but not necessarily Morse code. A2A Signalling by transmitting a modulated tone with a carrier, so that it can easily be heard using an ordinary AM receiver.
