Here's what I've collected so far to set up a node (maybe 2 if I can find another site): 1 2.4Ghz P4 computer (maybe 2 or more) running linux. 3 Digium TDM400 cards populated with 5 FXO and 5 FXS interfaces internet connectivity (dsl or T! at node sites and the colo facility I have rackspace in if I need a reflector - need hosting?) 1 FT-817/FT-857/FT-897 pots connectivity at most locations. VoIP account as necessary I know I need a few arib boards but how do they compare to http://www.hamwlan.net/images/FXS-SIMPLEX-RADIO-V2.jpg What else do I need? What could I put up? the simplex vs duplex thing has me a bit confused. 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 I'd like to put up a HF/VHF/UHF remote, maybe 2 that can be configured to linn between different bands and modes a static way in by radio fixed frequency, maybe a repeater but I don't expect great coverage in these locations (linking from them is possible though) other things? possible node locations include: phelan pomona irvine wilmington downtown Los Angeles Telecom hotel (difficult to attach radio ports here but maybe a good place to interlink with IRLP/EchoLink/SkypeLink) I'd like to get building soon.
