[NLRS] Re: hsmm and msmm

[Ray J]

 it sounds like the 900mhz stuff gets through trees and stuff better 
than the 2.4 ghz stuff... better for long haul the way i have read stuff..

 but .. remember.. The first 6 or 7 channels of the 802.11b stuff is is 
in the amateur band... so there is already alot of consumer and higher 
end stuff available...

I thought something like this would be cool to play with...but I already 
have to many irons in the fire..
