The Norcal Digital Amateur Radio Club is a small club formed in part to set up a "fill-in" D-Star Hotspot at the foot of Mount Diablo, which rises 3,849 feet above sea level just east of the San Francisco bay .  While the area is fortunate to have a D-Star repeater up on the mountain (the Mount Diablo Amateur Radio Club W6CX port C), there is an area just south of the mountain where coverage is poor to non-existent.  At best, we get R2D2 nearly all the time in this area.  We are close enough to the mountain that intervening hills and peaks get in the way or cause multi-path. NDARC was formed to set up K6DDV to provide D-Star Hotspot coverage for this area.

Currently, the Hotspot software consists of G4KLX DStarRepeater and ircDDBGateway.  The PC is connected to a gmsk modem (sometimes called a node adapter) which interfaces with an analog FM radio. 

The G4KLX software supports DPlus/REF, DExtra/XRF and DCS linking.  An ircDDBGateway has been defined, allowing Callsign Routing.  The software also supports CCS callsign routing. 

More information about this approach to extending the  D-Star network is available at http://www.k6jm.com/dstar.
