Rick, When did MixW become free? We, for years, have been able to download it
for a trial period of no more than a couple of weeks, then it stopped working,
until paid for. Its been a few years, but I think it was around $60.00 about
3-4 years ago, still a good bargin, since it works so well, and has many
different modes. Its logbook though, cannot even start to compare with
DXKeeper, nor its spotting section with SpotCollector. It does have an
interface that works well with DXLabs, and I used that for a couple of days
(checking out some digital modes) about a year ago.

Subject: Re: [digitalradio] RTTY decoding
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?

Hi folks,
I'm a student and interested in RTTY decoding principles. 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 ?
