I've decided that this is the best piece of software doing what it does that I've seen. I am using it with Ubuntu 6.10. The PSK is superb, and I cannot get over how well it decodes even the weakest signals. I've tried MixW, PSKDeluxe, Digipan, etc. and this one is great. The RTTY is also very good. As easy, if not easier than Mix W. FeldHell seems also to work as advertised. The CW decoder is the best one I've ever seen and that includes CWGet. I really like the QRZ feature it has in the entry panel. Just right click a call, put it in the field, hit the button, and it will get all the info from QRZ. The rig control features so far are easy to use, via Hamlib, and I've been able to export my log to XLog with no trouble at all. This is a truly wonderful, stable, easy to use, piece of software and I'm very impressed!
