Adventures in Callsign Routing

Callsign routing has been around since the earliest days of D-Star. It has also been little used. However, with the proliferation of Pi-Star based hotpots, callsign routing and D-Star have been given new life. Your Pi-Star installation includes a piece of software called ircddbgateway. It truly is a gateway to a whole new way of looking at D-Star.

The first piece of the puzzle is to get comfortable with callsign routing. I invite you to give me a direct call on my D74A HT. To do that, you’ll need to configure your radio with a memory that is setup to use your Pi-Star as a gateway. While that is outside the scope of this article, the general idea of the D-Star configuration (using the ficticious callsign N0TME) is:

 R1: N0TME B ; For a B (70cm) module
R2: N0TME G ; To use as a gateway
MY: N0TME ; My callsign

Now for the fun part. Normally, you’d use CQCQCQ as the destination callsign. This is the standard if using a repeater or a reflector. But, you COULD put a callsign in that destination field. Put “K2DLS P” in the destination and if I’m around, I’ll answer. Note that the P identifies my portable and must be in the 8th character position of the destination (UR) field.

There are also destinations that are not individuals, but are Smart Routing Groups. Try DSTAR1, for example. That is a very active routing group operated by the folks at QuadNet and it offers a lot of multiprotocol connectivity. There is even a net where users check in from D-Star, DMR, and Fusion and everyone can hear everyone else! Be sure to disconnect when you’re done (DSTAR1 T).

You can also configure your own legacy Starnet group on your own Pi-Star for you and your friends to chat on. This can be found on the expert menu for ircddbgateway. We’ll talk more about this in a future post.

In the meantime, I’m waiting for your call.
