Harold:

I love that word "any" especially when it is contained in the FCC rules :-)  
This would indicate that FM used in conjunction with R/C would be legal then; 
All they appear to be concerned with is occupied bandwidth. Cool :-)  Am I 
reading that correctly?

If so, anyone out there have a commercial Motorola or General Electric Two 
way radio that's type accepted for 27.255 ?  Drop me a line privately if you do 
:-)

BTW, what were these high power radio control links authorized for in the 
first place? Knowing that, I could approach some of those users for some old 
equipment :-)
