DSDPlus2p523

[dave3825]

What bat files are you using to start both fmp24 and DSDPlus?

Post the message saying it can’t find the dongle.

Post what windows device manager show the dongle as under usb devices.

if i launch dsd+ first, I get this error when i launch FMP24.
FMP24 launches I get this

Like I said, I don't use the other items even though I do have another RTL-SDR I can plug in, but all my basic tests, have been just dsd+ and sdsharp and I get all the data I need.

heres 52.525 in NXDN 12.5

Also,



What antenna is the dongle connected to and how close is the transmitting radio to that? Gain can be set to 0.0

DSDPlus - What's this error?

I am parked dead om my local simulcast' CC but DSD+FL isn't messing with it. I can recieve and decode other p25 systems further away. I have in the past managed this system just fine, I'm at a loss after countless hours reading threads here and Googling. Any comment is welcome.

Dave; Again, as mentioned, I have never used FMP (whatever), only dsdplus.exe. Nothing else.
been using DSD+ for years, and since the last few updates (Fastlane) I have not played with the GPS till
i got my 5600 and doing some testing for a customer use FAfo setup here.
Antenna, stock antenna at 0 db with sdsharp. (see my previous photos)
The radio is in low power, and on a GP5 Triband up 35 feet, so no it's not getting radiated like mad.
The radio sits on the floor with a remote kit (KCH-19 head) sitting on my desk and the deck 4 feet away from the PC on the floor.

Still, 2022 I was getting GPS from my 5700, 5800, nx-800 on a trunk system, all worked fine while I was ironing out the APRS via NXDN issue
which by the way, the GPS is wrapped in the Data stream and hard to pluck out of the NXIP stream from the conventional repeater, so
the idea of APRS with NXDN got nixed. HOWEVER, I was able to decode the Voice and GPS while transmitting (GPS would show up in GREEN) while going through the NXDN Trunk system at 4800 baud, AND even on simplex.

This time, I am trying 12.5 or 9600 baud since the 5600 only does 12.5 NXDN on low band.

Hope this clears up things.

Are these not your pics?







How are you feeding signal to DSDPlus?

I am guessing he is using SDR# and virtual audio cables to connect to DSDPlus. Then when FMP24 is started, it cannot find a SDR. It also would explain not having a single SDR choice and all the other greyed out options


Assuming you have all your files updated, main programs and base files.
Close ALL your SDR programs, not just DSDPlus related. Airspy/SDRSharp, etc

Have the RTL-SDR plugged in.
Start FMP24 via the batch file provided in the DSDPlus Base Files called FMP24-CC
You should see the program start using the one SDR
Start DSDPlus with the batch provided called 1R
They should communicate with each other.
You then can enter the frequency you are trying to monitor. The signal should

Looks that way.



He says he never used FMP24, but posts pics of it in use.

Antenna, stock antenna at 0 db with sdsharp. (see my previous photos)

Have not seen any pics of sdrsharp's spectrum or settings, let alone at 0 db. But do see FMP24 running with gain maxed out while keying up the radio.





While it may have worked for OP in the past using sdr# and cables, for to get the most out of DSDPlus FastLane and enjoy all of its features, its best to use it the way it was intended with one of its included tuners (FMP24, FMPA or FMPP). Not with sdr# and virtual cables

 

[cg]

and if a radio was keyed up close to the SDR, it would not be out of the realm of possibilities that is no longer working

A gain of 49.6 is WAY too high.

Keep it between 16 an 28.

Dave and others, not a greenhorn with DSD, I just do not use FMP, yes I HAVE IT IN THE DIR, but no, I don't use it.
You pointed that out in the picture cause you said to try that, just saying.
Would be nice if you showed where your side of this conversation with GPS decoding on your dsd+.

Setup recap:
SDSharp with VAC feeding DSD+, been doing this for 15 years, again not a greenhorn.
The view of sdshrp is on another screen but just to clear the air, here is the screenshot.

RADIO HAS GPS VIA PTT as shown in previous comments with photos of GPS on PTT enabled.
As you see, OTAA paints, and the monitor window shows it


BUT there is no GPS decoding from .523
SO Is the Firmware from Kenwood broke, or is the latest version of DSD+ broke?




SHORT OF going back to 2020 (2.242) versions of DSS+ to see where gps was broken, I wanted to see if anybody else is seeing the same thing.
I have tried all 6 of my radios including my 5400 (700/800 portable) and DSD+ is not decoding the GPS.
Photo of my 5600 KCH-19 display from Friday. So yes, GPS is working.




SO, here is the end game, IF GPS is NOT being sent, then I have a problem with Kenwood's release of 5.24 F/W and have to get with tech support to get this resolved.
IF you guys are saying you can see GPS from YOUR Kenwood radio, and with the latest version FW and DSD+, then show your settings versus armchair QB'ing.

Any no, RTL-SDR is not blown, because I can copy FT8 on 20m with it just fine.

Your right, so show your settings.

For Dave:

Just FYI


My UID 3274, that was decoded with DSD+ using SDSharp, monitoring the NXDN48 Trunk Site I was control channel watching while keying my radio on the bench. BEFORE 2p523 update.

Any example files to go along with this would be helpful, but then again, I may only use it 1 time just to figure out why GPS is NOT decoded.

Your input will be looked at. Again, I don't use FMPx for scanner stuff, just basic DSD and SD#, working on getting my NXCORE and other functions FUNCTIONABLE for ham radio uses..

Are all 6 radios using new firmware?

Photo of my 5600 KCH-19 display from Friday. So yes, GPS is working.

By no means a radio expert, but, while the gps in the radio is showing where it is, could there be an issue with the radio transmitting that info?

SHORT OF going back to 2020 (2.242) versions of DSS+ to see where gps was broken, I wanted to see if anybody else is seeing the same thing.

I have not seen any reports of it not working. Lrrp.exe has changed maybe 3 times between 2.242 and what your running today, 2.253.

Using Sdsharp and virtual cables adds more crap and possibility of problems to the equation. Quite possible a setting in either got bumped or something.



In all honesty, since your using other software not related to DSDPlus (sdrsharp and virtual cables) (which both have settings that could have changed) and radios with updated firmware, I myself would try what @cg suggested in post 69. That eliminates any issues sdrsharp and vac could have. And you would have an instant answer.

 

[dave3825]

Just to add to the above, should you try FMP24 with DSDPlus to rule out vac or sdsharp issues, after you click on FMP24 window to enter the freq, which is referred to as focusing , keys G/g is gain. One increases and the other decreases. If you’re going to key up the radio, at least set the gain to 0.0.

 

[TheButcher]

Your right, so show your settings.
View attachment 184251

No point sharing my gain settings. My situation signal strength will be different to yours.

Gain settings are not inside FMP24.cfg. They are set / stored inside your .bat file.

BTW, no reason to modify stock fmp24.cfg file. Nothing is to be gained here gps wise or other.

Justification: Too much gain introduces interference. You want the inverse bell-curve to occupy roughly 2/3 of the scale. Yours is at the top and overloading hard producing IMD etc.

You do run LRP.exe for GPS, right ?

Gain settings are not inside FMP24.cfg. They are set / stored inside your .bat file.

They can be adjusted in FMP24 using G and Shift G for up/down
