Welcome to DVSwitch
Purpose
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
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: DStar on DV Switch Mobile
Derek William Haden <facebook@...>
As I understand it (Could be wrong) you have to enable DStar in DVswitch, and you will need a DV dongle, because the emulator is fine for DMR, but not for DStar.

Re: The audio in DVswitch App mobile, with 4G/LTE is distorted.

Okay, thanks, Steve. I have the VODAFONE competition in Spain.
I have tried it with several mobile phones and with the latest versions of MMDVM_Bridge and Analog_Bridge. If I am in the same Cedula of the Vodafone tower, it doesn't happen, but if one is in movement, it begins to happen that distortion of the audio only in RX, in TX the audio is emitted well.

Re: The audio in DVswitch App mobile, with 4G/LTE is distorted.
I might suggest that the issue is with your carrier and signal to 'tower channel' To me, it seems obvious that your signal is either misreported by phone/tower and it is narrowing the bandwidth to your detriment. OR you are on a congested 4g segment doing the same which is more likely, especially if you are using a 3rd party lease like 'straight talk' etc.. because you are 3rd/4th tier priority for bandwidth. It could be something else, but that pops out at me. I would not
adjust your system.

We will test but I can tell you both Mike and I use it on 4G/LTE
daily.

EA5GVK Joaquin
If I force the mobile phone to use the 3G network, you can hear the audio on the DVSwitch all right.
But if I use the 4G /LTE network the audio starts to sound good, but after a few seconds it is distorted. I have already tried it on different phones. I have also tried it with both emulated and physical ambe and it is the same. Last version mmdvm_bridge and analog_bridge, as well as the last version mobile app.

Re: P25 to DMR issue
It worked because it ALWAYS TX to RX and RX to TX.

Do,

It always, TX to RX RX to TX. If you still get a error from MB, Start AB_P25 ONLY netstat -unap Look for AB, it will show you the ports AB is listening on For TLV it should be 34103 Now stop AB Start MB run netstat -unap Look for MB for TLV it should be 34100

Well, no jou! It gave me the same error again. Ports are set but still not good.
I have reached my miniscule knowledge of Linux. I'm going to step away from it and hope a fresh look will help. I feel as though I am Missing something very obvious but it hides in the dark! Not giving up though. Thanks for the assistance WB5EKU

Mike and I have discussed it and you may see it at some point in the
future. It's on the ever growing stack of "round toits"

Re: P25 to DMR issue
I had entirely too many instances of AB_P25 and AB_DMR running.
All shutdown now, I will kill MMDVM_Bridge then start everything fresh. Thank you for spending so much of your valuable time on this. It is appreciated. Hope to meet you in person some time, lunch will be on me. I'll let you know how this starts up. I did find a couple of typos in the bridge.sh script to start it.
