Welcome to DVSwitch
DVSwitch is a set of tools and programs related to provisioning and operating Amateur Radio digital voice networks.
Purpose
The purpose of DVSwitch is as follows:
1) Allows “local” networking during an outage of the regional national/international network server.
2) Allows a local network operator to “blend” upstream feeds from different Networks (capital N on purpose). These Networks can’t get their act together and learn how to play nice with each other (everyone guilty as far as we are concerned). They may not like people doing this, but the solution is to grow up and work with each other, and not keep trying to force people to take sides.
3) Allows local segregation of localized traffic with more flexibility.
4) Allows experimentation with linking and how it’s done (part 97 specifies experimentation and advancement of the radio art are a core part of amateur radio).

Mission Statement/Position
Our stated position is:
WHEREAS the Networks continue to be largely islands and are not working together to create a unified network of Networks.
WHEREAS no firm reason has been given by any of the Networks why a *competent* local network operator cannot make this work effectively.
(US ONLY)
WHEREAS 47 CFR 97 (Amateur Radio Service) specifies that a core component of amateur radio is experimentation and advancement of the radio art [97.1(b)].
BE IT RESOLVED the core group of US amateur radio operators and experimenters organized around the DVSwitch project, and in the spirit of USA 47 CFR 97 and its intentions, support the *responsible* and *thoughtful* use of digital voice networking tools to create localized networks that will interconnect to the national/international Networks, and will support users of its tools in order to do this in the most effective and sustainable way possible.

Re: DMR Timeout/Beaconing
#brandmeister
#mmdvm_bridge
Stefan, There is already a keepalive function built into MMDVM_Bridge, that's how it knows whether or not the connection has been lost or not. Looking at your logs, I see duplication of lines which suggests that you may be running MB in two instances. If that's the case, make sure that the two instances are using separate sets of ports assigned to the program. If you're intending to run one instance of MB, then check to make sure that you don't have any other instances of it running before you start it. Steve KC1AWV

DMR Timeout/Beaconing
#brandmeister

mi0pyn@...
Hi all,
I have a question about the DMR Network side of MMDVM_Bridge. On a test system I have running, connecting to the BM UK Master on the DMR side, I have an issue where the Master connection is dropped every 120 seconds exactly: M: 2019-04-25 17:51:14.327 DMR, Logged into the master successfullyBefore I start bugging the Master sysop, is there some heartbeat or beaconing that can/needs to be put in place to keep the connection alive? The time is exactly what I'd expect to see if there was a TCP timeout somewhere, but tracing that is likely to be very time consuming so I was wondering whether there was some way of enabling a heartbeat every 60 seconds or so. 73 Stefan MI0PYN

Hi Rob,
I am not sure what you want, but if you look here https://www.hubnetwork.uk/getting-started you will find links to resources etc. for setting up allstar on a Pi. Also have a peek at the RPG node link on that same page and you can see Peter's Video of his pre-made node ( lots more on his you-toob channel https://www.youtube.com/channel/UCWBDIDu7jYuvLRB4PLeO4RQ You can contact Peter (G7RPG) and he is always willing to help ad advise (in real time) if he is available :) the Hubnet UK is a great place to ask questions on this side of the pond too, you can get to it via echolink Node number 973498 (M0HOY-L) Once you have a node setup , making DVSwitch talk to it is not hard if you are not scared of editing config files :) Good luck, Neil M0KNC/MU0KNC

For context, this is the net referred to (doh! Hit send on the way to find post): I don't have a video, but one of the nets I run is starting at 8pm Eastern (0000h UTC) tonight if you are interested in listening in.

Yes it is weekly.
Also, when referring to something posting a while back that you are referring to, it is useful to have it in your email so others don’t have to search to understand context.
Best regards, Fred N7FMH

So is this net every Saturday night? or Second Saturday of the month?

Re: Audio stream of DMR talkgroup.
I would modify USRP_Audio to print the PCM values to either stdout or a named pipe and then you should be able to use the Lame encoder just as ASL does.

Re: Audio stream of DMR talkgroup.
I would like to try it without ASL, something like: MMDVM_Bridge -> Analog_Bridge -> USRP_Audio ->Lame ->Ezstream . Can't figgure out a working solution, what is the best way to feed the audio from USRP_Audio into lame or oggenc ?

Re: Audio stream of DMR talkgroup.
Jeff Lehman, N8ACL
You wouldn't even need to setup a public node if you didn't want to to use ASL. Set it up as a private node on your server and then viola.....no one could connect to the ASL node, but you would than have a dedicated audio stream and wouldn't even need to try to reconfigure AB or MMDVM to make it happen.

Re: Audio stream of DMR talkgroup.
Jimmy,
toggle quoted messageShow quoted text
I do it with MMDVM_Bridge -> Analog_Bridge -> AllStar -> broadcastify. I don't see why it could not be done with MMDVM_Bridge -> Analog_Bridge -> USRP_Audio -> Broadcastify. It would be a matter of understanding how the analog audio is process in ASL to send it to Broadcastify: outstreamcmd = /bin/sh,-c,/usr/bin/lame --preset cbr 16 -r -m m -s 8 --bitwidth 16 - - | /usr/bin/ezstream -qvc /etc/ezstream.xml it is like this: MMDVM_Bridge -> Analog_Bridge -> USRP_Audio -> lame -> ezstream -> Broadcastify. Hope this helps, 73, Steve N4IRS

Audio stream of DMR talkgroup.
Hello, I am trying to set up an audio stream of our DMR talk group for the internet, does anyone have any information on this? I am thinking this can be done with Analog_Bridge. Thanks alot Jimmy K3CHB

OBP does not have any concept of master or peer. Both ends are the same. There’s no difference.

OpenBridge Server?
Hi Everyone,
Been using dmrlink, hblink to establish our own standalone system like we used to have when we were on the c-Bridge. I have to say since we got everything setup we are quite happy and it's been fun learning the new scripts / software to make this all possible. I do have a question though. In light of what has happened with the BM DDoS attack's we are trying to break our system apart into public / private services. Our setup consists of a c-Bridge for all our DMR MARC feeds, a IPSC Gateway running HB_Bridge / IPSC_Bridge and a routing gateway that ties the IPSC Network and HBP (MMDVM) networks together. I have been reading in the form how the OBP can pull feeds in from the BM network and see that its function is to push/pull feeds from a server. I was wondering if HBlink can be setup as an OBP master to allow me push our internet network feeds from our routing gateway over to a secondary routing gateway that would only be used for public hotspots? I know this can be done with multiple HBlink instances but i was looking for a solution to route everything accross and not need to manage a 2nd rules file or another set of config files. Thanks, Ted/KE6YJC

Re: DV Switch Mobile
Hi Mark,
I am running a raspberry pi 3 and the app together. The rpi3 connects to other hubs to access the all-star network. If you want help setting up a rpi3 with the app them you can email me. I am listed on QRZ.com I also run MB7ILV and MB7ALV in the northwest.. 73, phil

Re: Bridging a P25Reflector and a YSFReflector?
Correct,
One MB and two AB (Transcoder) We are going forward with the change. No timeline yet but since MB is being worked on now it will be added. Steve N4IRS

Re: The digital side of DVSwitch Mobile
Steve That sounds like a fantastic platform, With work and travel I haven't been able to follow the progress of forums, This is something I'm very interested in learning more..Especially with my analog to digital project that I hope to start as soon as I wrap up a few other non-ham projects..Congratulations to you and the DV-Switch team on the progress and all of the time and hard work involved....Now for the important question? What kind of beer? Best Regards Rick n9umj
