Been reading much hullaballoo on the RTTY reflector about a new program by David, G3YYD, called 2Tone. According to people who are much smarter than I, its decoder beats MMTTY hands down. I have no experience with it but am not one for ignoring a better mouse trap, so to speak. Anyone in the club have any experience with it? Since I’ve heard nothing about it here I figured not but it never hurts to ask.
When I get the time I’ll download it and try it out, perhaps side-by-side against MMTTY (the only true way to tell which is better). The NAQP RTTY next weekend might be a good test, if I can manage to download it and figure it out.

G’morning, Pat:
I have been using/testing 2Tone for a bit. I use it in the Additional Rx Window when enabled from the DI Setup. I have not observed that it beats MMTTY hands down in every situation, but that in some situations it does decode better than MMTTY and in some situations MMTTY decodes better than the 2Tone. And, since I have not done any detailed comparison between the two decoders, I can’t be any more specific than that. For trnasmitting, this was developed as an AFSK tool, not providing FSK capability, however, when used only as an additional RX window, you still transmit in the basic MMTTY environment so FSK is not an issue. I believe that I saw something lately that he has incorporated a pseudo-FSK capability, but I have not tried it out.

Thanks for the additional info, Ken. I had missed that 2Tone is for AFSK, but do understand that it must be used alongside a RTTY program like MMTTY. I’ll give it a whirl and see what happens. I’m concerned about computer resources so that’s something to keep an eye on. I read on the reflector that 2Tone’s benefits are most apparent with S3- and below signals, and that above those signals both programs decode about the same. That would make sense from the perspective that a relatively “strong” signal should be decoded well by any decent software.
At my station, since I have no antennas with gain, I deal with a lot of S3- and below signals (I’m one myself) so perhaps it will be of some benefit.
