Thanks Eric,
It will be for experimental purposes mainly with a fairly low duty cycle. I was
looking at the UHF 470Mhz band because I can get radios cheap for those freqs.
I am not sure about the seperation I am not interested in large power
outputs, I am looking at 5w max.

You have the basic idea. If someone has 10 radios, they use 10 IDs. The
radios need not scan all groups - only those 10 used in their company. I

LTR is good for businesses, contractors, etc, but it does have

In a good system the difference in access time should not really
