Here&#39;s what I&#39;ve collected so far to set up a node (maybe 2 if I can find another site):<br><br>1 2.4Ghz P4 computer (maybe 2 or more) running linux.<br>3 Digium TDM400 cards populated with 5 FXO and 5 FXS interfaces
<br>internet connectivity (dsl or T! at node sites and the colo facility I have rackspace in if I need a reflector - need hosting?)<br>1 FT-817/FT-857/FT-897<br>pots connectivity at most locations.<br>VoIP account as necessary
<br><br>I know I need a few arib boards but how do they compare to <a href="http://www.hamwlan.net/images/FXS-SIMPLEX-RADIO-V2.jpg">http://www.hamwlan.net/images/FXS-SIMPLEX-RADIO-V2.jpg</a><br><br>What else do I need?<br>
<br>What could I put up?&nbsp; the simplex vs duplex thing has me a bit confused.&nbsp; my experience with true duplex is in a linked system where if 2 people talk at once you hear both and cross band monitoring of my own transmissions
<br><br>I&#39;d like to put up a HF/VHF/UHF remote, maybe 2 that can be configured to linn between different bands and modes<br><br>a static way in by radio fixed frequency, maybe a repeater but I don&#39;t expect great coverage in these locations (linking from them is possible though)
<br><br>other things?<br><br><br>possible node locations include:<br><br>phelan<br>pomona<br>irvine<br>wilmington<br>downtown Los Angeles Telecom hotel (difficult to attach radio ports here but maybe a good place to interlink with IRLP/EchoLink/SkypeLink) 
<br><br><br>I&#39;d like to get building soon.<br><br>Eric<br>
