[App_rpt-users] d-star?

Mon Aug 13 05:29:56 UTC 2012

I guess my reply to this never made it.  I'm not suggesting,
recommending or endorsing a TRBO to DSTAR Bridge, patch or intertie.
Merely mentioning that it would be nice to use the local slot on my 8400
linked into allstar NOT $star.  As others paved the way before I did,
I'm finding that using allstar to link analog machines via private WLAN
seems to be a great way to build a system.  Having a TRBO node would be
nice.  

Allstar has been so nice I'm considering dumping echolink connects all
together since 98% of them sound horribly OVERDRIVEN and just crappy.

And yes the folks at dmr-marc, dci and trbo6 don't want analog on their
systems.  My machine is linked to others in the state for emcom so being
able to tie analog to digital is a good option to have.  

Connecting an XPR4550 to a URI on a digital channel sounds NASTY.  Tried
it, the only way to go would be via IPSC which probably isn't going to
happen.

FROWN on it?  I kid you not........

I run 2 of the Hawaii MotoTRBO and 1 of the Las Vegas MotoTRBO.....

The first time I hear a interconnect from D-Star they all go dark.....

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.
