Usually a WSPR station contains a computer and a transceiver, but it is also possible to build very simple beacon transmitters with little effort. For example a simple WSPR beacon can be built using the Si 570, [5] or Si 5351. [6] The Raspberry Pi can also be used as WSPR beacon.
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.

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.
For a low-power transmitter you can use Raspberry Pi with unipager [5] and MMDVM-modem [6] installed, and to make the coverage area several miles, a radio amplifier needs to be added to its output. [7] The coverage area of the transmitter can be up to 20 km (12 miles), depending on the terrain and the height of the antenna.
WSJT-X is a computer program used for weak-signal radio communication between amateur radio operators.The program was initially written by Joe Taylor, K1JT, but is now open source and is developed by a small team.
The Raspberry Pi Zero v1.3 was released in May 2016, which added a camera connector. [40] The Raspberry Pi Zero W was launched in February 2017, a version of the Zero with Wi-Fi and Bluetooth capabilities, for US$10. [41] [42] The Raspberry Pi Zero WH was launched in January 2018, a version of the Zero W with pre-soldered GPIO headers. [43]
PACTOR is a radio modulation mode used by amateur radio operators, marine radio stations, military or government users such as the United States Department of Homeland Security, and radio stations in isolated areas to send and receive digital information via radio. [citation needed]
