World Wide Routing for DSTAR

Hello to the group,

The gateway is now turned on and now we can play around with routing. But here is the catch.

The routing is a new world wide routing system call ircDDB (built by the Germans). It will route to both D-Star system that joins the world wide routing scheme.

The two D-Star systems that can handle routing are the US ROOT, which is made up of only ICOM and one Home brew system; and the Multi-Trust Servers that the Europeans built with the help of a few here in the US. There system is made up mostly of Home Brew and some ICOM systems. Of course the DARPA gateway (KJ4NYH) is built under home brew network (Multi-Trust Server). So with the new routing scheme we can now route to US root or anywhere else that has the same system.

More US gateways are joining this new routing method because it’s faster than the US ROOT routing.

You can view the dash board at http://ircddb.net/. Look for Gateway KJ4NYH on the dash board with a green light that means it ready for routing.

So what can or where can we route to? Well you can route repeaters/area gateways and also call signs that are placed in the UR Field, i.e. W4AES is the gateway for Orlando, FLA so my UR field will look like this—> /W4AES C.

Give it a try and see what will work. Just check out the dash board and look for US calls.

GMSK DSTAR Repeater Hardware $100

New GMSK DSTAR Repeater Hardware Project $100

The two photos below are of the new GMSK Modems that will act like a digital repeater controller. They are able to pass D-STAR signals. These two cards will enable the local repeater to connect to other internet based DSTAR Gateways and reflectors. Will W4WWM is in the process of programming the PIC Chip with new Firmware.
