You wouldn't do it that way.<br>

Depending on your hardware, you can have several radios connected to the <br>
same AllStar box. There is no need for relays and more complication.<br>
Set up a remote base radio connected to the AllStar box. If the <br>
Internet goes down, link the repeater to the network with the remote <br>
base radio.<br>

Going down a different path, that isn't LOS:<br>
There are at least two companies making wifi cards for your favorite <br>
wifi router boards (RouterBoard - StarOS - Ubiquiti, etc.) that operate <br>
in the 420 - 450 MHz area. They are 5 MHz wide compatible (channel <br>
splitting - cloaking). I'm not saying you should use them as it *may* <br>
not be within the FCC rules for the US, but they are available. Please <br>
don't turn this into a "FCC rules" or "proper use of bandwidth" thread.<br>
