Hey, here's a problem I just ran into. In fact, it reproduced a couple of times now. So probably once a year, I scrub and reset my p25data file. So I started up FMPA/DSD+ with the usual batch scripts to monitor a local P25 system (which is very busy.) It was running for about 5 minutes when DSD+ appeared to lock up. (It actually didn't but it lost its network sync with FMPA.) The DSD+ application is definitely not responsive. I have to use task manager to kill it. So it's getting stuck somehow.

I relaunched everything and it ran for about 15 min before doing the same thing. It's been running for about another 15 min and it's (so far) running fine. The last time it failed, FMPA was still running and I only launched the 1Ra script to confirm it was a DSD+ issue. It started up and initially complained that another instance was still running but then it kicked off and started to decoding fine.

No other changes were made, so I'm not sure what's happening with DSD+ here. If you guys can think of any debug procedures then let me know. I did create a debugger dump with the first crash but no symbols for DSD+ and it didn't reveal anything useful. (User mode crash dump.)

And yes this is with version 2.523 and there are no file sync issues.

One minor note: with the initial run, I did notice the activity window text get all out of sync. The frequencies were filling up so fast that a few channels (the UI text) were overwritten by the new frequencies. I don't know if a UI issue would cause any of this... but thought I'd mention it.

2.523 question
Has the NXDN GPS decoding been removed from DSD+ ?
Trying to work on a few things and I am not seeing the GPS string (usually in teal or dark green) not populating in the data output window.
and not showing in the RAW data window even though I have the radio pulsing every 10 seconds trying to figure out if the code was changed or not.

Thanks

Not changed or removed, did you check the DSDPlus.LRRP folder and see if it is loading/receiving, are you sure the agency is still sending it OTA?

it's my radio(s) and yes, I have I have it turned on.
And I see the GPS data burst on SDSharp, but it is not decoding it, nor when set to auto, and no I don't see it when I am keyed up either.
Use to when I was debugging it for APRS use on the NXDN WW CORE, right now working on getting the nx-5600 working on 6m and Business band for a customer..

November 2024 is the last time it recorded GPS from my radio when doing a test.

You do have NXDN 4800 and or 9600 selected?

Is anything populating in the file DSDPLus.LRRP?

Do you have data/voice following on and or do you have data calls set to L/O by chance?

Combined CC/VC is greyed out on mine. Yes, all formats are enabled.
signal is 9600 NXDN.

The X in FMPX means either Fmp24, Fmpa or Fmpp.

So when your radio tx gps, do you see it on Fmpa?

I am not near any of my stuff today but I wonder if it needs to be in combined for it to do the keep data.

What are you using for the SDR dongle? You might need to start FMP24 and DSDPlus using a batch file with info in it.

Sorry I missed the PS with RTL-SDR.

If you are using a RTL-SDR as you say, you should be using FMP24
I am and works fine with SDsharp, but when I run FMP24 cant find device.

In the past, DSD+ use to decode the GPS and print it to the screen in the monitor box, hence why I am asking for guidance on this.
Never used any of the other modes, just basic sniffing and CC monitoring of NXDN CC stuff. And the occasional ham nxdn projects I work on with NXDN.

currently testing NXDN on 52.525 from Central Florida. so If you hear the nxdn96, copy it to me, let me know what you see and if you see the GPS string transmitting also.
