WSJT
Weak signal ham radio communication
The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation. ... -

AVR beacon
A hamradio beacon project on an AVR MCU
AVR beacon project utilizes a new approach to RF signal generation using SQDDS method (making RF signals directly from the software, based on a pre-calculated periodic bit-sequence). It is mainly used by the hamradio operators to set up various radio beacons for different purposes, mostly for radio waves propagation discoveries. CW (continious waves, Morze code) is a main modulation mode. Other modes like PSK and FSK are planned to implement in the future releases. User can enter any ASCII text to send it to the air. Transmission rates and modes are configurable from the input text. ... -
