Re: Looking for a better way to bridge YSF to DMR

YSF narrow, or YSF wide? If YSFN there's no need for the DV sticks, as YSFN is AMBE. If you're using YSFW, which is IMBE, then you'll want the sticks since software vocoders seem to have a tough time making the audio quality something you want to listen to.

Now, that being said...

There's a couple options here. Number one is you can try YSF <-> MMDVM_Bridge <-> MMDVM_Bridge <-> DMR. Connect one MB to the YSF reflector, and one to Brandmeister. Also, make sure the ports on the two MB instances are set to send/receive to each other. I think you may need YSFGateway between MB and the YSF reflector, but it's been a while since I've set it up... Number two is YSF2DMR, but that's outside the scope of DVSwitch. Both of these options will work for YSF narrow.

If you're using YSF wide, you'll need to put Analog_Bridge in the middle, so that the data to/from DMR gets transcoded from IMBE to AMBE and vice versa. That's where you'll need the DV sticks.

The looping thing, it might be caused by someone with two personal hotspots running on the same frequency in close proximity to each other. This is a common occurrence on Brandmeister, where someone has a hotspot in their car and one at home, and you get looping audio when that person's car pulls back into their driveway. Checking the ID that's transmitting when you experience the looping audio may give a clue as to the offending hotspot.

Looking for a better way to bridge YSF to DMR

Gary Mackey <Garymackey@...>

I've been searching the group and  Wiki section and finding a wealth of information almost to the point of information overload :-). I'm trying to find out if there is a better way to bridge YSF to DMR vs our current configuration. A way that would give us audio level control between DMR and Fusion and visibility into the number of DMR connections would be idea.

Our current configuration is WiresX Room 40557 (Ohio-Lnk)  that is bridged to YSF 48038 (Ohio-Link) using an OpenSpot (original). Our YSF reflector is being bridged for us by the BrandMeister team to TG31399.  Our WiresX room is running MS server 2018 and our YSF reflector is running on Debian. Both servers are hosted at the same location. This configuration has been in place for about 1.5 yrs now.

Over last 4 to 5 months we're started to experience randomly what sounds like looping audio from the DMR sides. I've uploaded a short video clip so you can hear what I'm talking about.

Some of the time this looping will clear on its own, most often we have to restart our YSF service to get it to stop. If your listening on the DMR TG side you don't hear looping. The looping is only head by the WiresX and YSF users. We have  ~25 repeaters/nodes connecting via Wires-X and ~30 connecting via YSF. Some of the local DMR repeaters carry us as a static TG. No visibility on how many are connecting on DMR side, and no information on how the Brandmeister team has us configured on their side. I only provided them with the DNS name for our YSF server and it magically was bridged.


I'm open to any suggestions. I do have a couple of the NW digital ThumbDV USB sticks.

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.

Hi all,

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 17:53:24.545 DMR, Logged into the master successfully
Before 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.

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

Hi David,

 

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.

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.

Alexander DC5AJ
 

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.

Steve N4IRS
 

Jimmy,
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

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

Hi Everyone,

Been using dmrlink, hblink to establish our own standalone system like we used to have when we were on the c-Bridge.

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.
