DSD+ LRRP

[Trooper_Dean]

Hello folks,

I have a problem with the LRRP. I see that DSD notes down that there is some activity going on with the LRRP but LRRP doesn't decode that data. If you know what I mean, it would be best to see the picture that I attached. Please tell me how to fix it, I would be really grateful!

You're using the free version. The Fast Lane paid version supports a lot more LRRP types (but NOT all, and no guarantee it supports yours). If you know what you are doing and are capable of capturing "raw audio" of the LRRP data, you could theoretically send it to dsdplusfastlane@gmail.com. And IF it can be figured out and isn't already supported with the Fast Lane version, it may be supported in a future Fast Lane version. But that is not going to help you since you are using the ancient free version.

Estimado Sr. Trooper_Dean.
Particularmente yo le hago muy poco caso a los datos que aparecen en la ventana de eventos del DSDPlus, en mi archivo CC.bat le pongo el comando de la verbosidad en 4 (-v4) para que me de la máxima información, para el caso del protocolo LRRP presto atención a los protocolos de formato de paquetes de datos (DPF) y punto de acceso al servicio (SAP), hay muchas combinaciones de estos con datos GPS, un ejemplo de ello es el siguiente:

2018.05.18 19:39:55 -DMR slot2 BS DATA DCC=3 Data Header DPF=[2:UcData] Tgt=100 Src=104 Conf=0 SAP=[3:UDP Comp] Blocks=3 Pad=4 Last= 0 secuencia=0

En las enviadas dos últimas líneas aparecen los datos de latitud, longitud, velocidad y azimut, en este ejemplo falta el grupo fecha hora de cuando la estación móvil su posición.
Espero que te sea útil este dato.

Hello guys, thanks for the advice. Got the Fastlane but I have a problem with it running. I am not a tech guy so I can't get it running alone with its SDR software. I tried to run in with the SDR Sharp as I did before, but I got this error. How to fix it? I don't need trunking, so could it work in SDR Sharp?

Just run dsdplus.exe all by itself. Then use the menu system to set things up. That commandline switch is no longer valid -- and you shouldn't be using the same commandline "tuning" switches for all signals anyway. The tuning is absolutely unique to the signal you are trying to monitor. So if you have a batch file that always sets the same tuning parameters, you are going to make signal capture of most signals worse.

No need to do any tuning it all or use any tuning parameters if you are monitoring a good signal to begin with. If you are trying to gather info from a signal with a 5 db SNR you need to find another signal. Maybe you can tune a 15 db SNR signal to be a little better with the tuning params. But if you are doing things right and are monitoring 20 db+ SNR signals, you'll never need to use tuning parameters.

Hello guys, I have a problem. I can't get Fastlane to work with SDR Sharp or alone either. I tried everything but nothing from both side. Can somebody please tell me or send me a video of how to do it, step by step? I just need DMR. I tried selecting VB cable but it's not an option. DSD+ worked flawlessly for me before.

I may have missed it. What SDR are you using? Examples include RTL-SDR, Airspy, SDRPlay, HackRF, etc.

 

[mtindor]

Control --> select PASSIVE DIGITAL MONITOR

Then exit DSDPlus. Then start DSDPlus again. Then navigate to the INPUT menu and select your VB Cable

I don't think there's any need to exit/restart.

I don't think there's any need to exit/restart.

I don't think so either. I'm sure the author doesn't intend on one having to do that. But I could have sworn that at some point over the years when I switched from CC/VC Monitor to Passive monitor, the expected inputs still didn't show up in the Input section -- and that I exited DSDPlus, restarted it and suddenly they appeared. Impossible? Maybe. Defies logic? Yes. But hey, I figured it could not possibly hurt anything so I added it in there. The OP was already having issues, and was wanting somebody to provide him with a step-by-step video (huh?!!!). I figured let's just nip this one in a bud.

A mí me ha ocurrido en alguna ocasión, especialmente si he tocado algo en las configuraciones del audio, al final nunca está de más reiniciar las herramientas, tanto el DSD como el SDR.
