Sine Wave Generatorupdated
- Freeware windows Wave Generator use the sound card's output as sine wave output. A built in sweep algorithm is used by audio hackers to measure frequency repsonses of their amplifiers
- Freeware windows program that allows you to store configuration of your audio mixer in a settings file, and to restore the mixer to
that state whenever you want. Useful for digital mode operations where different dsp programs may require different audio in and out settings.

- Audio voice keyer Microphone input, speaker output Live microphone enable
Record/play audio from twelve memories
Display text of recorded audio
Transmitter keyed via serial (com) port
Loop (with variable delay) audiooutput
- A freeware program to dig out weak signals buried in noise, functionally similar to the excellent FFTDSP of AF9Y, but with the added bonus of real time audio filtering of the incoming signals. Just point and click with the mouse, and the selected signal will stand out from the QRM and noise.

430MHz ATV transmitter
- ATV transmitter on 430MHz band used with special transmitting tube named 5894 for final stage. Run about 10W average for TV signal and 20W at synchronous peak. Final stage control gird modulation works well for NTSC color video signal and good at audio as well.
Rig to Soundcard Interface by M0UKD
- Practival project that contains two isolation transformers, one for AF from the tranciever to the line in on a soundcard, and one from the audioout of the soundcard back to the mic / data input of the radio. Both of which are variable inside the interface via two preset resistors.
