WSPR (pronounced "whisper") is an acronym for Weak Signal Propagation Reporter. It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT.
A large-scale beacon project is underway using the WSPR transmission scheme included with the WSJT software suite. The loosely coordinated beacon transmitters and receivers, collectively known as the WSPRnet, report the real-time propagation characteristics of a number of frequency bands and geographical locations via the Internet.
WSJT versions up through 7.06 r1933 (referred to as colloquially as WSJT7) and earlier were aggregations of previous versions, and as such WSJT7 contained 16 different modes (FSK441, JT6M, JT65 variants A - C, JT2, JT4 variants A - G, WSPR, and a preview of JT64A).
Data can include object Global Positioning System (GPS) coordinates, non-directional beacon, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data.
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) 5290.0 kHz: South ...
Jonathan Campos, Samuel Lilley, Danasia Elder and Ian Epstein, the crew who died on board American Eagle Flight 5342, have received honorary awards from their airline.
I know nothing about Esperanto, but I am a radio amateur familiar with WSPR and WSJT. WSJT is a computer application developed by K1JT, Princeton Nobel Laureate Joe Taylor and associates. WSPR is one of many protocols WSJT can decode. "Anon's" guess above is correct.2002:6167:78C9:0:0:0:0:1007 22:25, 28 March 2023 (UTC)
Fldigi (short for Fast light digital) [4] is a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem.The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB or FM transceiver to the computer's headphone and microphone connections, respectively.
