SDR Tx Software
Software Defined Radio Transmitter Software, written by Peter Martinez, G3PLX. Takes microphone input and generates the I/Q output drive for a quadrature upconverter forming the heart of an SDR Transmitter.
The software offers : One or two soundcard operation, Tuning / CW tone output, automatic microphone gain adjustment, LSB/USB/AM/FM modes, amplitude and phase balance.
SNDemo.exe Test your ability to detect CW or a tone in noise. Choose tone frequency
S/N ratio, CW message / speed and output filtering
Automatic signal detection and S/N measurement. Algorithms to automatically and reliably detect signals buried in noise,
while minimising the false alarms for auto detect systems
WSJT Logger Produces a log file of all WSJT Decodes, use for JT4 / JT65 beacon monitoring.
Install in the same directory as WSJT.EXE. The software works by looking for updates to the ALL.TXT file, extracting new data to the log file
