You have learned to untangle and reshape the fabric of reality in harmony with your wishes and music. British Columbia Wireless Amateur Radio Network.Skills: Choose three of the following: Any skills of your choice Spellcasting Level: 1.If the idea of running Mark, KB9KHM's windows based "hotspot" linking software for a permanent repeater installation doesn't thrill you, never fear, Dextra is here! (This is a very close basis of G4ULF's project) The retrofitted repeater system should be tuned for maximum 3 KHz deviation for best bit error ratio. (As pointed out for the simplex hot spot use, most 9600 baud "data ready" radios will work.) If you build or convert your existing repeater system, you can also keep backwards compatibility for repeating analog.Īll you really need are direct (varactor or varacap) drive to transmit the GMSK data, and a discriminator output for receive. An Icom D-Star system one radio module, RPC controller and gateway runs about $3,000. Satoshi's project has caught a lot of attention ( and some flack), because you can construct the node adapter for about $75. So you can get by with a mini-hotspot board, and just one PIC. Now KB9KHM's HotSpot software can emulate that. His blog is a running log of development of a D-Star repeater that links to the worldwide dplus network running on homebrew components and standard UHF FM rigs.ĭuplex use of the node adapter used to require two 18F2550 PIC chips running his code, instead of the one. I suggest taking a look at David, G4ULF's blog. Most of the bugs have been worked out, and the official non-stripped down Satoshi, GMSK node adaptor board can be used to make or convert an existing repeater for D-Star, with the capability to talk back to gateway servers for interlinking. Mark, KB9KHM developed some windows software so one can use the node adapter as a simplex node to talk back to the gateway server of other D-Star repeaters. In the QST article it was talking about using Satoshi's board as D-Star Simplex Hot Spot. There was a tid-bit about this in the July 2009, QST, Eclectic Technology column by Steve Ford. I have also written about Satoshi's GMSK node adapter. This of course is less than ideal as it's a carrier activated system, left open to intermod and such. In the past I've written about a passive D-Star capable repeater using a couple Maxtracs.
