Wayne,

Give me the details of what you want to do, rural, city, distance, inside or 
outside buildings, what the guys in the shop do, etc.  Been in the business 
since Marconi, well since 67 anyway.  Help is on the way.

Only thing I can relate to it is cordless phones.  Years ago (circa
1994) I was in an industrial environment of concrete block, rebar, metal
roof, etc with lots of electrical noise.  A VP wanted a cordless phone
for roaming shop use.  To test, I brought in a early gen cordless I had
at home.  It got all of 20ft from the base before loosing it.  900MHz
phones had *just* come out, so I scored one that was returnable (Best
Buy had just come to town, wow.)  It worked for a couple hundred feet
from the base, but we returned it because the volume was insufficient to
hear the thing.

Since then, there are all the 2.4 and 5 GHz phones.  From what I
understand, the higher frequencies propagate further through
unobstructed air, but are worse then 900MHz at penetrating barriers.
ie:  unless you're in a pasture, the old 900 is often better.

I don't know what freq's the radios work on, but I'd guess they're
similar to residential cordless phones.

HTH,
