I enjoyed a drink and a meal with Justin, G4TSH on Monday evening. One of the things we talked about was some software called MMVARI. This software to decode RTTY has the ability to decode a number of streams. Ideal if you're running a pileup from a DXpedition. Or, for those of us at home, to have a display of RTTY activity across a portion of the band.
You can see it in action from CE0Y/I2DMI in this video
From some quick googling around it looks like the software can be integrated into the N1MM contest logging software for RTTY contesting. I know one DXpedition group who are planning to use it too...
Haven't downloaded this and tried it out myself, but it definitely looks of interest.
