[App_rpt-users] d-star?

[Stephen - K1LNX]

There's a 26 pin jack on the back of the MOTOTRBO radios, so it  could easily be hooked to a URI (well at least on the XPR 5550, which is what I am running, not sure about other models. I think the 4550 has it as well). And I am also unsure if the audio is present in digital mode, it's not on the repeaters, but unsure about the mobiles. It should be though, there are several software packages out there that actually depend on a radio being connected. 

Native bridging? I don't think that will be easy. There's a product out there that will allow you to hook a radio to it and then bridge it to the TRBO network, but it's not cheap (about $2,600). Motorola is also very tight lipped about their protocol. I am working on getting accepted into the developer's program, but if I do get in I have to sign an NDA and I don't think I can make anything I potentially create open sourced because of it. I think there are people that have done what I describe above though, seems like I've heard some chatter about it. Believe me.... I would LOVE to see a "chan_trbo" or better yet a "chan_dmr" and be able to link both Hytera and MOTOTRBO together in a app_rpt box, but the nature of the closed IPSC protocols for both may prevent that from happening. It's not impossible, the protocol could easily be studied with a packet dump, but would probably take some serious code to make it all work. 

The bigger problem with all this is that the MOTOTRBO network operators (DMR-MARC, DCI, etc) may frown on such an installation. This is the reason I have not pursued this myself yet, there is a strong (and rightfully so) belief to keep the network all MOTOTRBO. 

Wishful thinking anyhow....

How about a similar connection to a mototrbo system.  That would be cool!

I know this is probably old hat to most, but I think I have the world's most connectable allstar server :).. 

I've now got a B and C module of D-star (via freestar*) that I can connect in, my own experimental XRF reflector, I can cross link analog to digital, etc.  What's most amazing is HOW GOOD IT SOUNDS, when the D-Star audio comes into the allstar server.

I just decided that I didn't want to do the rptdir thing, so I'm using chan_dstar and the dextra_client.. And it really sounds good.  I'm scratching my head as to why this was so frowned on in the beginning of time (not from the allstar guys, but the d-star guys).

Anyway, I think if I had everything connected up, it's like 2 full duplex repeaters, a full duplex IRLP connection, and a d-star gateway, but 2 simplex bases, one for d-star one for allstar.. Good think I had a whole bunch of 25W dummy loads :).

since I got everything working, I just figured I'd share. while it wasn't brain dead easy, it wasn't too difficult either.
