Server Update:
Rexx and Otis are both new and run on the
latest software and new servers located in the PNW
region and connecting to Kennewick c-Bridge. This
is a substantial improvement over the original servers.
We will update Bridget and Wes soon.
West side servers will be the last to be addressed as we
have limited time and resources. Our
Talkgroup Picker lists
the talkgroups that are available on our MMDVM servers
as well as our repeaters.
If
you are a member of
PNWDigital, please join our
MMDVM IO Group.
Only members will be provided access
to our MMDVM servers. Be sure to include your name,
call sign, location and radio ID number(s) in your
subscription profile so we know who is requesting
access and can set-up credentials.. Peter
is an open public MMDVM server but with limited
talkgroup deck into our network.
Members may request server access by Emailing
pnw-mm-servers@pnwdigital.net. Please let us know that
you are a member of PNWDigital.net and your call sign,
other additional
information also be included if you wish to share it. The tech team
will respond to your request.
If
you receive your credentials, please to not share
them. Refer anyone, even a person who you know is a
member, to our MMDVM specific IO sub-group page: www.pnwdigital.net/mmdvm/ (this
page). |

Bridget was
our first MMDVM
server portal
deployed to access
the PNWDigital network
directly. We
chose to use
"people" names to
easily distinguish
the new servers from
our repeater
city/site names. We
have since expanded
our portals to
include other talkgroup decks as
well as in-state
hosting of our
servers by way of a
single VM hosting
multiple instances
of the MMDVM
servers. Our
effort now is to
perfect and publish
this multiplexing
approach much the
same was we did for
W6SS's
single instance
method.
We are also using
groups.io to
discuss and update
or efforts.
The PNWDigital MMDVM
project is a package
of programs made up
by many smart people
who have developed
the necessary moving
parts. Vance,
W6SS created "ipscbuild",
which enabled most
anyone to be able to
deploy the Python
programs without
major experience
with Linux and
Python. The
goal has since been
to stack up multiple
"Bridgets"
(MMDVM-IPSC
services) onto a
single low cost
virtual machine
provided by a major
data center VPS
hosting company.
And doing so in a
way that the common
man can duplicate it
with little
experience in Linux
and Python.
Our multiple use or
stacking of
instances was
created by Dylan
KI7SBI with his
implementation
of Docker for the
multiplexing.
Dylan's first
Dockerfile
is what we call
Suzy, which
is our MMDVM server
tailored for the
east side users (of
Washington).
We will ultimately publish
the scripting and
documentation much
the same that W6SS
has done with his
ipscbuild
script.
We also have a
public portal (Peter)
available for
non-Members. Anyone
is free to try it
out or just use it
to test out their
MMDVM Client
set-ups. See
our
MMDVM
Matrix
to determine which
talkgroups are
available via Peter.
We have 2 servers
for Peter, one in
Bremerton and the
other in Spokane.
|
| PNWDigital's MMDVM servers are
now private for our
members use only.
We have deployed a public server called
Peter for limited use
by non-members.
Do NOT release any MMDVM server credentials OTA or
otherwise. Refer members to our
Wiki for that information. Non-members
should only have access to
Peter which is openly shared on the Web for
it's ability to demonstrate our project to
interested groups as well as to provide some contact
to PNW from the outside on talkgroups that are not
otherwise available via Brandmeister.
All portals have DNS addresses available.
Please use them rather than the older IP addresses.
We will be moving the servers around the state and
any moves made will be transparent to our users if
users use the DNS addresses.
Be sure to put TG 9 in
your Rx group for all channels in your zones
for the MMDVM server
annunciation.
Be sure not to put
your hotSpot on any repeater output or input/output
frequency as it likely will result in looping and
render the server useless and busy out a timeslot on
the c-Bridge. WWARA and our community codeplug
now support
suggested
frequencies (and
pairs) for power
digital devices such
as hotspots.
Typical client devices used on PNWDigital are the
"spots";
open,
ZUM and
Nano or just Google:
this for wider MMDVM information. |
This
particular project is
based on the great work of
multiple folks going back 4
years or so. All software is
open-sourced and available on
GitHub by
Cort, N0MJS
and his crew of supporters. Also
kudos to and for the fine
assistance of Corey N3FE, one of
the USA Brandmeister admins who
initially shepherded our efforts at
PNW DMR. Also to Vance,
W6SS for being the one who coded the
installation script
(still used by our
Dockerfile) and explained
how it worked, which is instrumental
to enabling Linux neophytes to be
able to install and manage their own
MMDVM projects. Dylan
KI7SBI, who put this project inside Dockerfiles to enable multiple MMDVM
servers to reside on a single VM.
and Finally, Albert, WB7AWL who
provided the Pi-Star image that
supports the MMDVM to IPSC linkage
for FM repeaters to connect directly
to our c-Bridges.
The
partner programs used are: dmr_utils,
dmrlink,
hblink and
Docker (set-up by
KI7SBI)
Running on Debian 8.9/64 at DO SFO
as well as well as CoLo'ed
machines located in Washington.
