Hellschreiber beacon project
- This web site describes a low power beacon system to be used for propagation and performance tests on the lower bands. The beacon offers CW (on-off keyed) modes and FSK modes; the traditional Morse ID mode, and Feld-Hell, another highly noise immune CW mode.
- A program to decode morse code (CW) via sound card to text. It can work as narrow-band sound DSP-filter also. No additional hardware required — you need only receiver and computer with a sound card. Can integrate with AALog logger.
