Usually the timing problems are related to "bounce-back" on fluttery/weak signals... signals that usually aren't all that copyable anyway, so it doesn't affect communications in general. But go kerchunk an in-band linked system 10 times fast and see if you get all ten kerchunks on the other end, etc. You'll see it. Subtle, but "not right" from an engineering standpoint. No big deal. Just not as "elegant" as dedicated links... Whatever works. I wouldn't trust a Public Safety Officer's life to it, but for ham junk... sure, why not? :-) -- Nate Duehr, WY0X n...@natetech.com
