This could more than DOUBLE the reliability of the local tactical situation
by actually reducing collisions at the inputs of digipeaters.

Though it does require the RGATE to be AT THE HIGH LOCATION.  But as the
internet more and more reaches every hill and mountain top shack, this is a
future potential we should be prepared for.  And it comes for FREE with this
IS-to-RF RGATE mechanism.
