I just made my first WSPR transmission on 630 meters and am absolutely amazed at the results with such a simple and cheap set-up. I waited until another Texas station started his evening receive session thinking no one further away could possibly hear what I have as a transmitting station.
Nine stations heard that inaugural transmission including one in the Cayman Islands. 
I'll post full details on the set-up on my blog tomorrow but it was dirt-cheap to get on this band with what's turned out to be a decent signal - again, much to my surprise.
Can't wait to learn what you're using.
