Disagree, but it's only semantics. We've got some DSP code here at work that'll kick an MT8800's ass any day of the week, upside-down, and sideways. And it'll do it on 336 phone lines AT THE SAME TIME. Last I checked, it will decode down to at least -31 dBmV and twist and skew numbers are better than the 8800. Standard voice falsing tests also perform better. And we didn't even write it, it's off-the-shelf DSP code from a vendor. But it wasn't cheap. So, we're not going to find that code or hardware in any ham projects, ever... (Actually I guess you could... they're relatively old AT&T DSP's, available on the open market, and the company that made the code is also out there... somewhere...) Maybe your idea is better phrased as something like this: "For low-budget jobs, dedicated circuits designed in the 1980's still do a better job than hobbyist level software DSP in PC's." :-) Nate WY0X
