color=#0000ff size=2>While we're (marginally) on the subject, does anyone have
thoughts (or good references) on FEC design for use with AFSK over FM? FEC
using convolutional coding and/or concatenated Reed-Solomon coding with baseband
modulation is pretty straight forward (or well-studied anyway), but things get a
little more murky with AFSK. I haven't found any reference on the subject
yet. Seems like you'd at least get different types of errors than with
baseband modulation.</FONT></SPAN></DIV>

can tell you from painful experience, it won’t work. The DECnet preamble
