I guess I incorrectly assumed that it would be a receive only station
unless it was coordinated with others. We have a whole bunch of Igates
in our small town but we share RF transmit load. Most are receive only
but one is transmit/receive and one is dedicated to transmitting WX info
only. So far I haven't found any problems with this arraignment and a
couple of advantages. The biggest advantage to having so many receive
only Igates is that if one internet connection (or radio or antenna)
goes down we have total redundancy. 

Forget where but UI-View does have an option to turn off Igating from
the Internet to RF.

Ditto.
