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: Stacato audio on DVSM

OK if I restart everything, from fresh reboot, with AB configured for ambe server, but ambe server not yet started. start amber server and restart AB So I am guessing that somehow the command echo 1 > /sys/bus/usb-serial/devices/ttyUSB0/latency_timer

Re: Cloud hosting
W8DSB ... does this mean you have all apps running in cloud. How do you access ASL node? DVSM -> DVS -> ASL?

So I copied from another location and replaced the DVSwitch.ini file and edited the two ports. And it is working now. No clue what caused the issue, but it is working again!

If all yuo want is ASL access, then use IAX protocol.
toggle quoted messageShow quoted text
Analog_Bridge uses USRP to connect to an analog client. That client can be ASL or DVS but not both. If you wanted to connect ASL to Digital Voice, you connect ASL via USRP to AB. If you want to add DVSM, you can connect to ASL via IAX. Steve N4IRS

Re: Analog_Bridge and Mumble server
Paul on6dp
Waldek, I have installed a mumble on my Debian, where HBLINK, Analog_Bridge and MMDVM_Bridge are also installed 73 Paul, ON6DP
De : main@DVSwitch.groups.io <main@DVSwitch.groups.io> De la part de SP2ONG Waldek
I like various radio amateur experiments. Currently running a test Mumble server which I connected via the python3 script from Analog_Bridge. Generally, the transmission works both ways, although I think that the script is very "raw" and requires work on it to work optimally. For end users exist client application for PC/MacOS or Android.

The local Mumble server uses the authorization based on the CERT key generated by the user and only the server admin can allow joining the channel where there is access only, for example, listening to audio from a DMR or a channel that allows you to transmit and hear via the Mumble <> AB / MB> DV bridge Has anyone tried or is having a working connection from the Mumble server to Analog_Bridge? 73 Waldek

Maybe I'm not being clear, you are showing 2 USRP connections to AB. It's either / or. Either DVSM or ASL not both.

Correct. The problem I have with the diagram is it is showing both
connections to AB. That may confuse someone trying to connect both
DVSM and ASL at the same time.

I showed DVSwitch at both points as one is using USRP (with port #'s), the other is using (iaxclient) as entrance points. (OPTIONS) For what I am doing now, I am using only the USRP direct into the Analog Bridge.

Aaron Groover
Good morning everyone. Just had a pretty simple question. I haven’t tried it but it’s worth a shot. Is there any possible way to have 2 dmr networks on the switch? For example BM on slot 1 and TGIF on 2.
Is that possible or would it be best to use HBlink and use my own server?
