Spektrum Technology

Tue Oct 25 09:56:24 AKDT 2005

So technically there could be cars, boats, planes and helo's all running in
the same vicinity with nary any problems of interference.

That would be great in developing a master plan for an R/C complex where
several clubs could support a site and with all activities in close
proximity.
