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: DR2 X connection options
In addition, the DR2X don't work with MMDVM modems, only the DR1X works without modification and MMDVM modems. The background is, as far as I understand, you cannot switch the DR2X to 9k6 mode (DISC in/out) anymore at the remote connector, with the DR1X this was possible. But I think, in principle, it could be possible. Inside the DR2 there are two main units from the FTM400 as I know, which have the option to work in 9k6 mode. Maybe you can use a FTM400 display unit for setup of the two internal TRX for 9k6 mode operation. WIth the original repeater control that don't work with the DR2X (DR1X yes). I assume YAESU that they deliberately removed this option (DISC in/out) from the DR2X.

Re: DR2 X connection options

Hmmm, I'll think about those offers ;) Meanwhile, is there a suggested way forward to implement DMR on a Tait? Hate to reinvent the wheel. I've tackled several MTR2000 conversions with both KC slide in card and external MMDVM modems, and once running they are truely amazing systems. Thanks!

I then tried the iPad and it was producing audio as well, although the button was briefly red, and the received audio was several seconds behind that from a hotpot. At least I may have a work-round. 73, David GM8ARV -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: david-taylor@... Twitter: @gm8arv

No audio from Windows DVSwitch dashboard
I'm a beginner with DVswitch, but I have it installed on a Raspberry Pi (on top of a working OS, I didn't use the .img), and it's working correctly both from a phone and from the Python program on a Windows PC.
However, when I press the RX Monitor button on the dashboard on this same Windows PC, the button turns green, but no audio appears. Using the same Firefox audio from the BBC Radio service is fine. I am using Firefox, but no audio with Chrome or MS Edge either. I've attached the Analog Bridge status in case that helps. I'm stuck on knowing how to chase this further.
