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.

Hello Chris ... after all this time, have you managed to make an analog web streammer work? ... could you give me a light in that direction?
Thanks!

Audio settings and other associated handsfree opitions
Richard W4JXA
A few years ago, when the application was in Beta tester mode, I listened to a presentation about what DVswitch would do. Most of those declared goals have been achieved. However, trying to use this application handsfree is almost impossible. Everything under "AUDIO SOURCE" still says "Not Implemented Yet"
Along with that, the TX screen button is way too small! Peanut, and Zello both have nice large buttons and both have the option to set up a non screen PTT. Great application for certain but please return to the Audio Source opitions and implement them. Otherwise I will only be able to use it for listening, and it's far too great an application to only use for RX 73 W4JXA Richard

Re: Location of the P25Gateway
Can I assume you tested it with your hotspot running Pi-Star. Are
you sure you disabled the firewall. I suggest for testing you use
the same port number are 10200 that way you know Pi-Star will allow
the port.

My Hotspot acts like the Gateway. It shows "Connected to 99539" and in about 3 minutes times out (I guess).

Comment By Steve a little over half way down the page. I have determined that the problem is accessing the P25Reflector server. It has a YSF reflector it that works fine. Ports look ok. Still digging into it. -- jb N4NQY

Re: Location of the P25Gateway
Sure, you can test on dvswitch.org port 43166 Dashboard at
<http://dvswitch.org/P25_DVSwitch/> That's what it's there
for.

Are you sure that it was P25 wide or narrow? Not YSF? URL?

It may be ok and the problem at the reflector, but there is so little to configure at the reflector. It does however seem to not be seeing traffic from the Gateway machine. Ports?? The look open.

Next step is reconfigure to go to a known good reflector (DVSwitch Test?). ?That will narrow down the location of the error. Just wish there were a few more error messages. After this I am going to try to document my eventual success. BTW I came across a post concerning adding txPortN and rxPortN, etc to the ini file to allow both Wide and Narrow P25. Did that ever come to pass? Curious, Wide is all I really want. -- -- jb N4NQY

Re: Location of the P25Gateway
That's rather odd. Mine worked first
go when I moved DVSwitch away from the machine running
P25Reflector. Just checked it now to be sure.
Is your reflector correctly listed in a hosts (either the main P25 hosts file or the private one) file on the gateway machine? If it's a public reflector, what's the TG number? On 6/1/21 2:50 pm, Jay wrote:

Gateway shows "linked at Startup to Reflector xxxxx" but disconnects shorty thereafter with a "no response from xxxxx, unlinking message.

I was using Hamvoip as I was trying to use a Pi4 (seems to be the only option currently for ASL + DVswitch, happy to be corrected there). I reinstalled with a 3b plus and the ASL Rpi image and installed dvswitch and setup the bridge, all is working now. I guess the extra Pi4 horsepower will have to wait for later.

Is the port number in the host file the same as the reflector? Are you sure the reflector is listening on the UDP port it think it is? (netstat -unap) Can your gateway connect to another reflector? Steve N4IRS

ASL->TGIF Prime

Justin Painter
Hello,
I have a Archlinux Hamvoip node that I pulled down Dvswitch from the repository and have ASL<->Prime TGIF working. I have the audio levels sounding pretty good after tweaking some on the Analog bridge gain settings. I do still have more delay in the ASL->DMR direction than I was expecting, in the 3000-3500ms range. It seems fine in the other direction (to ASL from DMR) When I say delay, I mean a transmission will key up on the ASL side and start talking and the first sentence is generally missed. I know I've got something set up wrong, but I am having trouble finding it! Thanks, AF5LW

Re: Location of the P25Gateway
As others have said, that looks like a
path (does the path exist?) or permissions issue.

Re: Location of the P25Gateway
Hi Jay, You might check the file location in the ‘ini’ file, but more likely, it is a permission problem. I change the ownership of the log folder to mmdvm:mmdvm, which usually allows the creation of the log file. Jeff WA3PNY
