My PSK modem has a patch (which I've done) for jitter. I havent got far
enough to test it out yet though.

Hmm - I'm not even sure of the status of IO-26 - I saw one post that said it
was not yet operational, and the weekly AMS bulletins are a bit quiet about
it. I've also seen different frequencies quoted for it!
