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.

First amateur radio satellite OSCAR 1, launched in 1961 Simple OSCAR beacon signal, 1962. The first amateur satellite, simply named OSCAR 1, was launched on December 12, 1961, barely four years after the launch of the world's first satellite, Sputnik I. The satellite had to be built in a very specific shape and weight, so it could be used in ...
This beacon is the main beacon for the South African Amateur Radio League located at SARL HQ in Johannesburg. The beacon and a number of other South African stations are running WSPR mode for experimental purposes. (WSPR is configured as Dial Freq USB 5287.2 kHz TX Freq 5288.7 kHz, which is within the channel allocation)
Nexstar has agreed to purchase WBNX-TV 55 from the Winston Broadcasting Co., meaning Channel 55 will again become the CW. The CW set to return to Channel 55 as Fox 8 parent company Nexstar buys ...
The CW covers just over 98 percent of television homes in the United States, with network affiliate over-the-air coverage in all of the top 100 Nielsen-ranked markets. [1] Stations are listed in alphabetical order by city of license. A blue background indicates an affiliate originating as a digital subchannel.
The single letter beacons can be classified into two groups, "cluster beacons" and "channel markers". A beacon "P" exists in both groups. A third group, called FSK beacons, is now extinct. The following sections list the beacons active as of December 2007, according to published listeners’ reports.
