* Build cabinet for #RCHWD site, must house computer, radios, power supplies, TNCs. Computer should have 2 serial ports and wireless network card. Computer obtained, build in progress.  Total count is 5 radios (1 6m, 2 2m, 1 1.25m and 1 70cm) and 6 TNCs (BPQ32 will be on all but APRS TNC, which will be linked to VM of Linux running Xastir for a digipeater/Igate).  The 6th TNC will be wired to "share" the 145.010 radio to give both BPQ32 service as well as a Linux based RMS gateway. '''***Update 5/11/09***''' Computer built on Dell, had problems with Linksys N card, transplated into IBM desktop, still getting inconsistant behavior with wireless card.  Going to return PCI card and locate Wireless Bridge.
