Re: DStar on Cloud Server

Patrick Perdue
 

How is the latency between your AMBEserver and the cloud VPS?

I ran a setup like that for a while, where pings were only about 2/4 MS between my home internet connection and the VPS, and all was fine. However, on another connection where latency was around 20 MS, things started to become choppy after a while. In my case, I was transcoding ASL/DMR, so not quite the same thing. I got better results running Analog_Bridge on the machine hosting the AMBE than connecting AMBE to a remote Analog_Bridge, even though I was just turning the packets around to the VPS again anyway.

All,

I have used W8RIK's excellent install document to set up an image on a cloud server. Works great on DMR, YSF, NXDN and P25. When I connect an ThumbDV/ambeserver on a RPi at my home, everything seems to work ok on all modes. Audio sounds good on all modes, including DStar. However, over time (20 minutes), the audio becomes choppy. The ambeserver rpi has the latency code installed. Anyone have success with this approach? Advice??

Re: Access to a Fusion FCS room #dmrlink

Steve N4IRS
 

If I remember correctly, at this time you can auto connect to a FCS room. (When YSFGateway starts) but you can not dial a arbitrary FCS room. This will be changing.

I note that FCS is enabled in YSFGateway.ini. Not sure if this is new. 

does this mean that MB can now connect directly to FCS rooms?

Seems to have done it. Thanks!


Re: Overdriven P25 audio

Steve N4IRS
 

I would try turning down the audio coming out of the DMR Analog_Bridge in the [USRP] stanza:
usrpGain = 1.10 
Change it to 1/2
usrpGain = .60

retest.

Re: FM Repeater to DMR Talkgroup? #best_practices

Weller Rudolf
 

Hello David,

that's a very interesting idea. I tried private nodes twice now, but it doesn't really work. I think my rtp.conf has the wrong configurations for nodes 1999 & 1998.

DMR to analog seems to work. When I press the PTT on the DMR device, I can hear the CW output and an acknowledgement sound from the same device, but no sound whatsoever from the FM device. No red LED signal on the UriX either... When I press the PTT on the FM device instead, nothing happens at all, and DTMF sounds aren't recognized either.

When I enter "rpt cmd 1998 cop 4 1998" directly into the Asterisk-shell, I can hear the sound from the DMR device and - with 1999 - also in the FM device. So the UriX seems to work. The startmacro in my rpt.conf is *31998.

When I enter "rpt cmd 1998 ilink 3 1999" into the Asterisk-shell, I can speak from DMR to FM, not the other way round though.

When I enter "rpt cmd 1999 ilink 3 1998" into the Asterisk-shell, neither DMR nor FM work. All I hear is a rogerbeep in the DMR device.

Maybe someone can help, cuz I'm at my wit's end.

Just write a script to do what you want, test it and drop it into /etc/cron.daily. Make sure the script does not have a extension (.sh)

If you are deliberate about keying up and waiting a second or so to speak I usually don't see the problem.

Re: FM Repeater to DMR Talkgroup? #best_practices

David Martin
 

Hi Rudolf, Mike, 
I would suggest ASL with two 'private' nodes say 1999 & 1998 one connects to the URI the other USRP (Analog_Bridge).
Connect 1999 & 1998 at startup in asterisk. 
There is no ASL involvement the only permanent link will be to DMR through MMDVM_Bridge.

Just a thought or two

Hey Mike,

I didn't necessarily wanna set up an ASL node. Are there other options? I was hoping to get a connection simply via MMDVM and Analog_Bridge, without an extra node. My problem with an ASL node is that it keeps a permanent connection, and I just wanna transmit to a talk group when analog FM is spoken. Kinda like a real radio device.

A COR signal is no problem, I have a Motorola GM360 connected to the URIx Interface

Thanks for the help

Well, your only looking for ideas. Stick around for everyone to read and comment.
I would imagine you might also be able to pipe from a sound fob to the usrp.
Never done it, but I think it would be worth exploring.
