Hi all,
I'm busy scraping together money for a D-STAR radio. Someone has
loaned me a dongle, and I've been playing around with that. I'm
reading up on D-STAR as much as I can. I have a couple questions:
I've read about the various Trust Servers, and I'm curious how it
all works. I read that there is such a thing as a "multi-trust"
gateway, which can't communicate with a gateway using the K5TIT
Trust Server. I also read that there is some work-around so that
Japanese stations and US stations (and presumably stations on
gateways in other countries that use the K5TIT Trust Server) can talk.
Is there a list somewhere of the other major Trust Servers, and what
countries they serve, and whether they have agreements with the
K5TIT Trust Server? Mainly I'm just curious about which gateways I
can talk to, and which I can't. (I heard about the unique situation
in France.)
My next question concerns D-STAR reflectors. I know that reflectors
are made possible by DPlus, thanks to Robin AA4RC. I presume that
these reflectors are just computers in server rooms with good
internet connections, and that a reflector doesn't have to be
connected to an ID-RP2C repeater controller. I'm curious, is there a
list of who sponsors and pays for these reflectors? It must be
expensive to keep a colocated server going, and I would like to know
whom to thank.

The K5TIT USTRUST is the primary trust server with the majority of
gateways around the world, it pretty much only supports Icom and G4ULF
gateway implementations. (400+ see http://dsync.dstarusers.org/)
The multi/Xtrust is a group of trust servers that have a smaller group
of gateways but are open to more gateway implementations (including
all on K5TIT plus others). (See http://uktrust.xreflector.net/multiTrust.php)
K5TIT and the Multi-Trust do not interoperate or update each other.
The Multi-Trust was seeded with K5TIT registered callsigns initially,
but you must now register on each independently.
K5TIT is setup to allow callsign routing information to be transferred
to and from the Japan Trust which runs an older version of the
software. Japan gateways do not use DPLUS, you must use callsign
routing.
IRCDDB has the mechanism to update individual station location
information (what repeater was station w1xyz last on) -- see http://ircddb.net
The K5TIT USTRUST does reflectors and linking using Robin (AA4RC)'s
DPLUS software (including DPLUS for gateways and reflectors, DVTOOL
for DVDongles, and the DVAP device ... it also supports the DVAR
Hotspot)
The Multi-TRUST could run DPLUS but mostly uses DEXTRA and a variety
of clients to accomplish the same effect as DPLUS (It has equivalents
to DVTOOL, Hotspot, etc.) You can find the software on the Yahoo!
group pcrepeatercontroller in the files section.
The DPLUS Reflectors are listed here:

The Dextra Reflectors are listed here:

Most of the reflectors are self financed and sometimes the bandwidth
and server space are donated but a thank you note (and/or
contribution) would be helpful. Not all reflectors are in data-centers.
