Anyone decording it yet? I see quite a bit of mention of the mode and software on the web.
I've done quite a bit with digtrx. It has two modes, RDFT and Ham-DRM. The sstv people are almost exclusively Ham-DRM, using a protocol which pretty much guarantees that people monitoring the frequency will miss packets. The receiving station in QSO asks for resend of the ones it missed, but you can't do that, and you need a perfect decode or the file is corrupt or useless.
I don't know much about RDFT mode, because if this is indeed what the whacko Cubans are using, it'll be the first time I've ever heard it. It just isn't used much by hams in this hemisphere, at least not hams in any locations I can hear. I can practically guarantee it's more forgiving than Ham-DRM when high redundancy is selected.
1700 is kind of iffy for the Cuban stuff this far west when conditions are as wretched as they've been lately, but I'll give it a try.
