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.
With a small hardware modification, TYT MD-380, MD-390 and MD-UV380 handheld transceivers can be flashed with a custom, free, open source firmware [12] to enable M17 support. In July 2024, a US-based company Connect Systems, Inc. released the CS7000-M17, being the first commercial off-the-shelf handheld transceiver with native M17 support.
MacLoggerDX is a full-featured amateur radio contact logger for macOS with Transceiver control, Rotor control, Callbook lookup, QSL handling (Hardcopy / LoTW / eQSL / Club Log), DX Cluster and spotting, and basic contesting support. It also works with WSJT-X to control the transceiver while making digital contacts, etc. HamLogBook by K6REA
The primary software for this method is developed by Jonathan Naylor. An example of a repeater system using this technique is the addition of D-STAR to the Yaesu DR-1X repeater by attaching the UDRC and a Raspberry Pi computer. [28] Icom D-STAR equipment Transceivers—D-STAR and Analog FM Capable:
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.
The TNC connects to the terminal and a radio transceiver. Data from the terminal is formatted into AX.25 packets and modulated into audio signals (in traditional applications) for transmission by the radio. Received signals are demodulated, the data unformatted, and the output sent to the terminal for display.
HackRF One is a wide band software defined radio (SDR) half-duplex transceiver created and manufactured by Great Scott Gadgets. It is able to send and receive signals. Its principal designer, Michael Ossmann, launched a successful Kickstarter campaign in 2014 with a first run of the project called HackRF. [1]
Members of the ham radio activity group at RWTH Aachen University designed and developed DAPNET from scratch as a modern software approach. [ 1 ] As of March 2018, over 90 transmitters were already in permanent operation, and the coverage area included parts of Germany , the Netherlands , Belgium , and Switzerland , [ 2 ] with Raspberry Pi ...
