Andrew, and all:

<yikes!> Sorry about the crummy spelling!

Thanks for the link. It looks channels 1, 6, and 11, are the best channel
choices for the maximum number of coexisting networks.

I agree it does not matter. In fact I imagine when we are operating in the
field, we should use channel 5 as the local network for general use (like
sending SMTP email to the Winlink mail server), and stick to 3 (or 1?) as the
rocket telemetry channel.

Well I guess that WiFi could be considered an experimental SS (spread 
spectrum)
mode in the eyes of the FCC. So in terms of fitting into a desired 
band-planned
region of the spectrum, we have put giraffes where the giraffes should be. :)
