Xpress is sent over CNN. The frequency varies by cable company because
CNN is on various different cable channels. The receiver is made by MACOM
(of San Diego I think) which takes a 9600 baud serial signal straight off
of some part of the CNN signal. I don't know if MACOM sells these receivers
separately, but enough disgruntled customers are probably out there that a
net news article mind find a used one.

I wrote software to decode the signal on a Sun workstation but never did
anything with it.

The thing I dislike most about Xpress (outside of having to pay a monthly
fee if I want the encrypted part) is the Copley news service which tends
to dominate the news feed. It is in my own opinion a pretty raunchy excuse
for a news company (including biased).
