WSJT-X
Software/Weak SignalWSJT-X if a software that offers specific digital protocols optimized for EME, meteor scatter, and ionospheric scatter, at VHF/UHF, as well as for LF, MF, and HF propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals more than 10 dB below the audible threshold. Popular modes includes FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, and WSPR ... / ...

Morse Code Beacon Keyer
Technical Reference/Beacon keyersThis circuit stores a morse code message as bits in an EPROM chip, the message controls a relay that keys a CW morse code transmitter. An Arduino processor can also be used in place of this circuit, that eliminates the need to build the circuit and program an EPROM. ... / ...
