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 ...
Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1]: 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. [2]
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 ...
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 ...
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]
The International Beacon Project (IBP) is a worldwide network of radio propagation beacons.It consists of 18 continuous wave (CW) beacons operating on five designated frequencies in the high frequency band.
In turn, propagation maps characterize the propagation channel between arbitrary pairs of locations. Radio maps can be used in a large number of applications, especially in the context of wireless communications. For instance, network operators can use radio maps to determine where to deploy new base stations or how to allocate frequencies.
This map shows all the countries that currently have an official Amateur Radio presence on 5 MHz / 60 m, whether it be by WRC-15, Article 4.4, Special Individual Permits, Trial and/or Emergency Basis, or any combination of these. The 60-meter band or 5MHz band is a relatively new amateur radio allocation.
