Gary,
Give me a DMR TG (BM) and a YSF Reflector IP and Port. I can spin up a quick bridge as a demo.

Hi Steve,

thanks for for your reply. I looked at the MB ini in the wiki and there doesn’t appear to be away to adjust the audio levels between YSFN and DMR. I look at Analog_Bridge and spotted a gain adjustment. Is it possible to use AB to bridge YSFN to DMR?

As far as our looping audio from DMR it doesn’t seem to be tied to any one person. If fact during our weekly net it happened on someone checking on a DMR repeater.

This is going to be one heck of a group. If this runs true to form, The conversations We are looking forward to between groups will yield quite a few ideas for improvements to existing products and some new goodies. We are looking forward to speaking with existing and prospective DVSwitch users. Mike and I will be available Thursday through Saturday. Come by and say hi. I'm honestly thinking of having a whiteboard. ;)

I've seen the same behavior with the WW6BAY YSF room connected to a DMR TG via a BrandMiester-provided link.  The audio coming from the DMR side into the YSF room is "overdriven" and clipping.  I've tried to contact the Brandmiester people to see if there is any tuning possible but I've never received any response.

That sounds promising. I’m not sure how Brandmeister has us bridged on their side but DMR coming into our YSF reflector is about 30% louder then our YSF audio and DMR users report we’re to soft on the DMR side.

What Steve said. The fewer steps you use, the better off you'll be. I haven't needed to adjust gain when connecting like digital modes using DVSwitch.

Gary,
You really don't want to use Analog_Bridge in a YSFn to DMR bridge. You will loose audio quality. You should not need a gain adjustment using MB to bridge DMR you YSFn. Since that type of bridge is the easiest to setup, give it a try.

It turns outthere were in fact 2 instances running, I didn't realise that the daemonised service was enabled by default and I was testing with an instance running inthe foreground.

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

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:

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.
