Download MixW 2.19. It is easy to install, free and you do not need much of a processor. It uses your soundcard as the modem and an HF radio to gather the signals. Your computer processor is the microcontroller, so to speak.
There are numerous sources for the engineering behind RTTY digital signal processing. Interesting stuff and it is a good place to start for young electrical engineers. IEEE usually covers this topic very well and their subscription rates for students are very low. What kind of HF radio do you have?

What methods/algorithms were used, what procedures has the best results ? Is it possible to implement a decoder with a microcontroller or does it have not enough resources ? 73 Sven
