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. They can be found on LF, MF, HF, VHF, UHF, and microwave frequencies. Microwave beacons are also used as signal sources to test and calibrate antennas and ...
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.
PSK Reporter is an amateur radio signal reporting and spotting network and website started by Philip Gladstone in 2014 which allows operators to see where their radio signals are being received. [ 1 ] [ 2 ] The platform works by collecting digital signal reports from software clients such as WSJT [ 3 ] and FLDIGI, [ 4 ] then mapping them to ...
An amateur radio net, or simply ham net, is an "on-the-air" gathering of amateur radio operators.Most nets convene on a regular schedule and specific frequency, and are organized for a particular purpose, such as relaying messages, discussing a common topic of interest, in severe weather (for example, during a Skywarn activation), emergencies, or simply as a regular gathering of friends for ...
The amateur radio service is unusual in the fact that it is regulated by international treaty. Worldwide amateur allocations are determined by the International Telecommunication Union [3] (ITU), which allocates global radio spectrum and satellite orbits, [4] develops the technical standards that ensure networks and technologies seamlessly interconnect and strive to improve access to ICTs to ...
These islands of intense ionization are called "sporadic E" and result in erratic but often strong propagation characteristics on the "low[er] band" VHF radio frequencies. The 6 metre amateur band falls into this category, often called "the magic band", will often "open up" from one small area into another small geographic area 1 000–1 700 km ...
160-meter band refers to the band of radio frequencies between 1.8 and 2 MHz, just above the medium wave broadcast band.For many decades the lowest radio frequency band allocated for use by amateur radio, before the adoption, at the beginning of the 21st century in most countries, of the 630-and 2200-meter bands.
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [1]
