PSK-31

I have been reading a lot about PSK-31 and; I think, digipan for windows. Is there a linux alternative that has all the features of digipan? One of the latest issues of QST talks about a kit for PSK-31 on 80 meters, once again they mention needing the windows software. Is anyone using a linus alternative, I don't do windows at all, not even a little bit and hate to start buying windows software this late in the game. joe
