The program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands. WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm.
[5] [6] The website takes its name from the popular amateur radio digital mode PSK31 and supports numerous digital modes, [7] [8] [9] but now the vast majority of digital modes recorded by the service are FT8 traffic. [10] Most traffic recorded on PSK Reporter is in the HF amateur radio bands but the platform also supports MF, VHF, and UHF bands.
VOACAP (Voice of America Coverage Analysis Program) [1] is a radio propagation model that uses empirical data to predict the point-to-point path loss and coverage of a given transceiver if given as inputs: two antennas (configuration and position), solar weather, and time/date.
SPLAT! (short for an RF Signal Propagation, Loss, And Terrain analysis tool [1]) is a GNU GPL-licensed terrestrial radio propagation model application initially written for Linux but has since been ported for Windows and OS X.
A waterfall display depicting several PSK31 transmissions at around 14.07 MHz. The green lines indicate a station that is transmitting. PSK31 or "Phase Shift Keying, 31 Baud", also BPSK31 and QPSK31, is a popular computer-sound card-generated radioteletype mode, used primarily by amateur radio operators to conduct real-time keyboard-to-keyboard chat, most often using frequencies in the high ...
It consists of 18 continuous wave (CW) beacons operating on five designated frequencies in the high frequency band. [ 1 ] [ 2 ] The IBP beacons provide a means of assessing the prevailing ionospheric signal propagation characteristics to both amateur and commercial high frequency radio users.
High frequency (HF) is the ITU designation [1] [2] for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
