pop and jitter at the start of transmissions from DMR

Patrick Perdue
 

Hi:

This is nothing new, but I'm trying to figure out where it's coming from.

At the start of each DMR transmission, when listening on Allstar, there is a small pop sound. I've been on some other Allstar nodes that appear to be using a similar configuration, though I don't know for sure, which don't exhibit this behavior. This occurs regardless of whether or not I am using hardware or software AMBE vocoding.

Perhaps related, but maybe not, lately, at the start of DMR transmissions, there is sometimes severe jitter for about the first second of audio, then everything is fine for the rest of the transmission. This is a problem if someone quickly keys to give a callsign, then unkeys again. Perfectly understandable with a DMR radio, but these very short transmissions end up completely broken on the other side of Analog_Bridge.

This could very well be attributed to the Brandmeister server I'm using. I'll investigate this some more. It may even be an ASL issue. This bridge is off-site, connecting to a larger Allstar node on a VPS, but directly connecting to the private node hosting the bridge through iaxrpt suggests that the connection to my larger node is not the problem.

I'm using the latest versions of MMDVM_Bridge and Analog_Bridge from Github as of this writing. Analog_Bridge.ini is all defaults, with the exception of txTg and AGC setting ,which are not relevant to this set of problems as far as I can tell.

Raspberry Pi 2 running ASL and DVSwitch, ThumbDV via AMBEserver. I also tried using a direct serial connection to the dongle from A_B, which worked about the same as using AMBEserver as far as I could tell. I have also tried playing with the jitter parameter of MMDVM_Bridge, but ended up setting it back to 360.

Hi, Ray.

Version 8 was reported to be no longer active.  Since v9 is out. And it's not viable to keep both versions.  Also, v8 had an old DVSwitch.

You can't upgrade via OTA from v8 to v9. Since it's got deep changes.  It must record image v9.

Greetings.

Re: ASL <> DMR <> YSF inquiry? #mmdvm_bridge

Steve N4IRS
 

A one to many configuration uses "like" modes. DMR, YSFn, NXDN are like modes since they are all AMBE. P25 and YSFw are like mode since they are both IMBE. D-Star stands alone. Any time you want to bridge to a different mode, you will need a transcoder,
We are working on example configs now.

I installed the new A_B yesterday morning, and enabled AGC. What a difference! Very smooth, and gets through analog a lot better with certain radios.

Thanks for the great work.

[Edited Message Follows]

We just posted some changes to the components, here is the. changelog.  Several of these changes will require significant doc for you to use so more to come:
AB:
  • Add AGC update including new settings
        • In AB.ini you can now set usrpAgc to adjust the threshold, slope and decay of the AGC
        • "Threshold" specifies AGC Knee in dB if AGC is active.( nominal range -160 to 0dB)

        • "Slope" specifies dB reduction in output at knee from maximum output level(nominal range 0 to 10dB) 
        • "Decay" is AGC decay value in milliseconds ( nominal range 20 to 5000 milliSeconds)

      • Add reloadDatabase remote command
        • This command (issued from dvswitch.sh) will cause AB to reload its internal database of users from disk.  This is normally done once every 24h
  • Add menu command (does not popup menu on mobile)
        • Like the "macro" menu for DVSM/pyUC, the menu command loads a transient menu into the client. 
        • Unlike the "macro" command (which now popups up immediately) the menu command just loads the menu
        • This command is most useful in conjunction with the OnRegister macro
  • Support USRP ping back (NAT keep alive)
        • Allow AB to respect a reverse keep alive from the mobile client for some NAT situations
  • Multiport transmit to support better bridge creation
        • This requires a full post all by itself, but the quick description is that a comma delimited list of transmit ports is now supported by AB and MB
        • The main purpose of this is to support better bridge architectures
        • Other uses include logging and streaming 
  • Allow macro variables with substitution
        • Again a single change that requires a full post.
        • Variables are now supported in the macro section of AB.ini
        • The variables are substituted by the shell before command. execution
        • The variables allow for much more concise command line strings
        • The variables make for much more readable macro definitions
        • Less dedicated scripts will. be needed as the macro definition can be defined in the section alone
        • Variables are exported to the environment and be used by client scripts for context
  • Better ini parsing error messages
        • When an error. is encountered in the parsing of the ini files, a better error message is. generated to. help diagnose the problem
  • Add warning if call not found in database (DSTAR)
        • DSTAR/ircddbGateway is picky and wants a valid callsign to operate.
        • This warning tells you that a call can not be found in the database that matches the DMR ID/CCS7 provided in "gatewayDmrId"
  • Add name lookup and metadata export
        • Metadata exported from the USRP interface now includes the first name and callsign of the DMR ID
        • The information comes from the database file loaded by "subscriberFile"
  • Change default transferRoot to /tmp
        • Change the default so that users who fail to set this parameter still function as expected
  • Make tune command able to invoke macros
        • The dvswitch.sh tune command/AB now supports invocation of AB macros using the same syntax (*) as DVSM/pyUC
dvswitch.sh
  • Inherit dir names from environment
        • Along with the variable support in AB, dvswitch.sh can now use AB_DIR, MMDVM_DIR and NODE_DIR from the environment
  • Use awk and not jq
        • On small machines (older Raspberry Pi) using jq would choke on large database files (DMR)
        • We moved bac to using awk which performs MUCH better and does not choke
  • Change ASL validation to a more visible node
      • Allow several commands to execute without ABInfo being present.
  • Add download and validation of user database files.
      • Support new AB commands reloadDatabase, AGC settings, etc
MB:
  • Change DMR networks on the fly.
        • The DMR tune command now support network selection.
        • The tune syntax. is PPPPP@AAAAA:###:OOOO
        • Where
          • PPPPP is the password for the DMR server
          • AAAA is the. FQDN (ip address) of the server
          • #### is the port that the DMR server is listening on
          • OOOO is any options that may be needed (XLX and DMR+)
  • Comma delimited set of transmit ports for each mode.
        • This will take a whole post to describe!  Maybe even two
        • The transmit ports in DVSWITCH.INI now take a comma delimited list of ports
        • These ports will allow you to set up single instance bridges with like mode partners with greater than two networks
      • NXDN remote command error silence (Just a bug fix)
      • DSTAR remote command was dropping into END_TX case. (just a bug fix)
  • Better error message for dvswitch.ini file parsing.
        • When an error. is found while parsing the ini files, a better error message is generated
  • DMR support for talker alias. DVSWITCH.ini has a new tag (TalkerAlias) in the DMR section.
        • This setting will be transmitted to the network on each transmission and can include your name, rig, location, etc
  • P25 Soft Id transmit and receive
        • Still a work in progress, but it is functional on decode
  • YSF split of narrow and wide TLV export to support transcode.
        • Wide mode YSF packets can now be sent to its own list of transmit ports using TXWidePort
        • This is independent of the narrow transmit ports
        • This allows you to transcode one side of YSF while keeping the other format free from conversion
  • YSF uses the latitude and longitude from MMDVM_Bridge.ini for the GPS location.
        • All transmissions will include GPS locations from the MB.ini file if non-zero
  • DSTAR slow data fix DSTAR ini file addition: message
  • Force MB to begin transmission if we did not see one (FCS bug)
  • Make MB return MMDVM and not _Unknown


Re: Changelog

Wow! Good job. Thanks


Re: Changelog

HL5KY
 
Edited

Thank you for the great work.
 
Here I have some issue with the new update. After updating binaries, I can't transmit on DSTAR. Connecting DSTAR reflector seems to be ok, as I could hear the other's voice. Pressing PTT made it red but no real TX was carried out. And in about 5~10 seconds, it became unregistered.
 
Please find the attached files, a part of MMDVM_Bridge.log and the result of './dvswitch.sh show'. As you can see, after pressing PTT, it changes to DMR by itself.
 
Joe, HL5KY.
 
p.s. TG450 is a static TG.

You dont need Hblink in between. 

Here is the working sample config:
MB.ini
[DMR Network]
Enable=1
Address=3103.repeater.net
Port=62031
Jitter=360
Local=62033   >>>> make sure change this, it will interfere with your first MB instance if NOT change.
Password=passw0rd
Slot1=0
Slot2=1
Debug=0
 
[System Fusion Network]
Enable=1
LocalAddress=127.0.0.1
LocalPort=0
GatewayAddress=ip or dns ysf reflector
GatewayPort=42000  >>>port YSFReflector

DVSwitch.ini

[DMR]
Address = 127.0.0.1             
TXPort = 35103                  
RXPort = 35100                  
Slot = 2               
[YSF]
Address = 127.0.0.1             
TXPort = 35100                  
RXPort = 35103                  
FallbackID = your id      
ExportTG = your TG               
Slot = 2 

Log in to BM self care and set the talk group.

73, Eric             


Re: ASL <> DMR <> YSF inquiry? #mmdvm_bridge

Steve N4IRS
 

The one to one bridge was the first method we came up with. What always bothered us was the complexity of a one to many bridge. Mike came up with a elegant "simple" way of making that happen. It is pretty much limited to "like modes" in this case, DMR, YSFn and NXDN which are all AMBE. Everything we do is to add power to the "partners" As we have said over and over "With great power, comes some complexity" (with apologies to Stan lee)

Re: ASL <> DMR <> YSF inquiry? #mmdvm_bridge

Andrew,
I would suggest you wait a few days. We just updated to allow MB to bridge or connect to all like modes in a single instance of MB. We are putting a document in the next few days.
It will look something like this:

ASL <-> AB <-> MB <-> DMR
               | <--> YSF

(best I can do with ASCII graphics)

that is echolink. suggestion change your time on sunday to like 2 am monday morning to reboot and that should alleviate your problem.  I run mine on a raspberry pi 4 and never rebooted unless I make a change in the system.
