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.

There were tlv and usrp entries that were similar....messing with those, but so far, no increase in DMR audio into the TG. This is a setup of two analog VHF and UHF repeaters with the intent of adding a DMR talkgroup through a cloud server. It works, but DMR audio coming out to the TG from the repeaters are very low.

Re: DVSwitch Server (and Pi-Star Hotspot) Dropouts When Network Watchdog Expires
#mmdvm_bridge
Joe Hussey
Appears to be fixed in DMR mode by changing Jitter Value from default 360 to 1000 (See DVSwitch MMDVM_Bridge.ini [DMR Network] and P-Star Configuration > Expert > MMDVMHost > DMR Network). Have not found a work around for other modes (YSF, etc.).

YSF to NXDN with YSFn & YSFw
Bill N2WNS
I'm looking to bridge YSF to NXDN but I'm looking to support both YSFn and YSFw. There are Yaesu radios can't send WIDE until it receives a WIDE signal and I want to make sure I can support that. Does someone have an example of this? I'm thinking that I have to use AB for this.

DVSwitch Server (and Pi-Star Hotspot) Dropouts When Network Watchdog Expires
#mmdvm_bridge
Joe Hussey
DVSwitch server (and Pi-Star Jumbo Hotspot) experiencing dropouts that coincide with "network watchdog has expired" error reported in MMDVM log files. Dropouts appear to be random. Any suggestions on a cause, where I should look next or a possible solution?
This "may" have coincided with my recent change in ISP (new router, etc.) from AT&T to Starry Internet. Log extracts:

Yeah, Sorry I had just got home from work and noticed it was down. It should be connected to 3104 but it's not showing anything on the dashboard. I connected to the node and did a transmission and nothing came over DMR. The Brandmeister dashboard shows the ID connected

Re: DMR bridge to Allstar - Loose DMR Master connection

Hello Wayne from Wellington New Zealand.
I have the same loss of DMR Master connection when using DMR Plus IPSC2. It stays connected for some hours or days but sometimes disappears from my DVS dashboard. I use the DVSM [* & 0] function to establish it again. Funny thing is that it appears to still put traffic to the New Zealand IPSC2 server even though the dashboard says it's not connected. NXDN, D-Star and YSF do not go missing except for an internet "blip" when I sometimes need to reconnect all of them. DVS is such excellent software and if drop of DMR Master is the only thing wrong then I live with it. There might be a fix sometime or it's caused by bad net from time to time and nothing to do with DVS. Here is my dashboard: http://zl2tws-dvs.ddns.net Best 73 and good DV to all. John ZL2TWS

Then I wonder if it's just a DVSwitch Dashboard display issue and the web interface is looking for the initial handshake vs a retry

I went back 5 days on the logs and the last entry on 3102 was Nov 18 18:39:58 dmrxbm Master 3102[908289]: Connection of MMDVM Host system 310022399 (3.144.15.211) removed Prior to that everything was fine and you didn't lose connection at all. since that time you have been connected to 3104 and never skipped a beat there either, other than one simple service restart I did over the weekend, and you were connected right back within 30 seconds. As I see it there was no issues at all.It never lost connection except for the time I restarted a service and when you moved it from 3102 to 3104. I never even saw it on 3103. Corey N3FE I have zero record of you on 3103
