RTCM's don't care what the frequency of operation is... just that one<br>
transmits and one receives.<br>
<br>
Pretty much like duplexers don't care what radios are connected to<br>
them... nor does Asterisk care what equipment is on the other side of<br>
the URIx ... COR/COS, Audio in, Audio out, PTT and Ground.<br>
<br>
It's up to you to figure out which radio gets what connection ;-)<br></blockquote><div><br></div><div>I'm pretty sure it doesn't care what antenna is connected either. <br></div><div><br></div><div>But this doesn't answer my question. Permit me to rephrase. Again.</div>
<div><br></div><div>Two split-site repeaters. Each repeater receiver has its' corresponding transmitter on a geographically distant site (that's what a split site repeater is you know! ;)</div><div><br></div><div>
The sites are linked with outdoor wireless ethernet 802.11an</div><div><br></div><div>Site "A"</div><div>6m TX<br></div><div>2m RX</div><div><br></div><div>Site "B"</div><div>6m RX<br></div><div>2m TX</div>
<div><br></div><div>Do I need two RTCMs or four?</div><div><br></div><div><br></div><div>Steve</div><div><br></div></div>
