DSD+ Fast Lane 2.165 - Trunked P25 - Group Call Question

[AB9NN]

I am seeing Group calls scroll by on my event log and hearing no audio. I got P25 Trunking working last night and heard clear audio. Is the print-screen below something I need to be concerned about or are these just data calls or why might I not be hearing them?

 

[DaveNF2G]

This happens in my setup as well. I suspect that one of two things might be causing it.

1- The VC signal is not received as well by the voice following dongle as the CC signal is received by the control channel dongle.

2- The transmission was too brief for the reaction time of the software configuration.

 

[mtindor]

Definitely not #2, given that some of those transmissions are 11+ seconds.

It would be helpful to have screenshots of both FMP24 waterfalls both DSDPlus Event Windows whilst a call is supposedly going on. It could be that the group(s) are locked out. It could be that the FMP24/DSDPlus #1 copy is not configured properly to steer voice traffic to FMP24/DSDPlus #2 copy.

Of course, any screenshot needs to be clear. Nobody wants to look at tiny, low-resolution screenshots.

Probably not the issue here, Once my VC copy stopped decoding and started outputting odd messages (like DMR while on a P25) and acting incorrectly. I deleted the DSDPlus.bin file and everything started up normally again.. Nothing else I tried got it working properly.. Probably never duplicate the problem again.. but it's an idea.. for those that have tried all else..

Whoa!!! Thank you. Seemed to have worked instantly. Do you know why and what the function of that file is? Looked like it had a current date. A good idea to include deletion of that file in my start-up batch files? I start everything through shortcuts in a folder that point to batch files and use alternate icons that resemble radios, phones, etc...

That's above my pay-grade.. Just know it worked! Don't recommend deleting it unless all else fails....

Wondering if that a file that the system uses for IP routing between instances of FMP24 for the trunk following process? If so, and if that's getting corrupted at some point, and if it always rebuilds itself, then routine deletion would seem a logical preventative action. Like limiting the data in a database where the structure was known to have size limitations. I checked the download for DSD+ Fast Lane 2.165 and that file was not in there, so it must be created on the fly at some point. Given that it's not part of the original software I guess the risk is that it's some data file and deleting it deletes data gathered from other runs of the software.

You guys are messing up a persistent setting like polarity inversion, voice monitoring threshold or audio volume level and then fixing it by deleting the file that stores those settings...

 

[jets1961]

In my case it was the polarity. Hit p in the DSD+ VC event window and audio returned.

 

[AB9NN]

I am not the only one that has access to my computer. It may be that a keystroke was made that I was not aware of. Or perhaps I made a stray keystroke. With the file, it seems the keystroke would be stored and persistent. Deleting the file returns the system to a known steady state. Seems to be working fine after deletion. With that being said - I am quite sure it was put into the system for a good reason. To each his own as my Mother loved to say, I guess..

Damn, that did not work for me. My trunk setup was working good but now on Cap+ trunked, the cc side displays group calls and it seems like nothing is being passed to the voice side. While 2 fmp24 and dsdplus are open, I can tune to a con+ or P25 and it works good. Just Cap+ is the problem. Guess I will back up my freq, networks, sites and radio id files and rebuild DSDPlus.

 

[slicerwizard]

Does DSD+ know what the Cap+ RF channels are?

 

[dave3825]

The freqs for the cap plus are in properly I believe

Cap+, 8888, 1, 1, 462.4500, 462.4500, 0   
Cap+, 8888, 1, 3, 463.8375, 463.8375, 0   
Cap+, 8888, 1, 99, 464.6375, 464.6375, 0
Cap+, 8888, 1, 99, 464.9625, 464.9625, 0 
Cap+, 8888, 1, 99, 451.3000, 451.3000, 0

 

[slicerwizard]

So you have the correct LCNs for only 40% of the channels?

I had similar experience. On the CC DSD+ Event Log press '3' It'll decode DMR voice on the CC frequency unlike P25 PII TDMA. Do the same in VC DSD+ Event Log window. Cap+ puts the CC on a time slot and keeps the other time slot open for voice. Usually on Cap+ voce will follow CC unless traffic increases sending traffic to another frequency while it goes down the list of LSN's.

One other thing you can experiment with when no voice happens is to reset the wav out device in both VC and CC DSD+ Event log windows. Press'0' in both then it'll tell you it reset wave out device. Then in both windows press '3'. If that don't work then close all of it and then reload it all again. After all if you're using DSD+ FL it is an alpha version and still being updated throughout the year per the statement in the email we get from the DSD+ decoding king himself.

My final thought for you is your LSN's are not quite right. You have multiples of the same. CAP+ is 1,3,5,7,9 and so on.
You want

Cap+, 8888, 1, 1, 462.4500, 0.0, 0
Cap+, 8888, 1, 3, 463.8375, 0.0, 0
Cap+, 8888, 1, 5, 464.6375, 0.0, 0
Cap+, 8888, 1, 7, 464.9625, 0.0, 0
Cap+, 8888, 1, 9, 451.3000, 0.0, 0

If ANY of those have changed you wouldn't know because no bandplan is transmitted. That requires serious frequency search manually and it's time consuming (FCC Database will help). If that entity changed frequencies then DSD+ will lose the rest channel and will keep search through the frequencies in DSDPlus.frequencies file for that site. If it is on a active rest channel and a radio is on a channel with no frequency displayed you wouldn't hear anything. Again, a manual frequency search is required or FCC database query.
