DSD-NEO help

[Marco192]

Hi guys,
first of all thanks to everyone working on this and other projects that allow all of us to have these decoding programs!

Hopefully someone can help me with an issue I noticed when testing dsd-neo:
when trying to listen to a DMR trunking network dsd-neo will not stay on the control channel. It finds the channel in the csv file, it decodes the parameters of the channel but it continues on to next channel in list (and so on in a loop. Am I missing something, some new command?

It probably works as a Uniden scanner, if it cannot detect any ongoing conversations it will continue to the next control channel in the list until it finds TG activity.

But perhaps you have another issue that it doesn't let you monitor any TG's you have programmed in a list that it should follow and skips all conversations that you at the same time can monitor with a scanner on that control channels site? You have the correct LCN numbers set to each voice frequency in the channel list?

It's not a problem that it will not follow, it's a problem that i will not park on the control channel.
It's a system that I now well, and have been listening using both dsd++ and dsd-fme. In dsd-fme it works as it should detecting calls and following them to the channels in the list.

It creates a log file, does it say anything suspicious? The t parameter are used for hangtime of TG's in trunked mode but hangtime for scan in non-trunked mode. In trunked mode it starts up by reading the channel list and then needs LCN values and also a TG list so those probably needs to exist and formatted properly.

What happens if you only have one frequency in the channel list and use non-trunk mode?

Thanks for the ideas and suggestions. I tried all of them and more.
I checked and double checked everything (channel list, group list, hangtime) - Nothing helps. Even when a call comes the "scan" continues, it is not following the call. This is my command, maybe someone can spot an error
dsd-neo -fs -i tcp -U 4532 -T -C bin\dmr_t3_chan_cn1.csv -G bin\group.csv -N -Z 2> NUL

I will take another look in its source code but when I looked at delay times I only found those two and it only had that t timer for a control channel in non trunked mode when it lost the sync and couldn't see any for a control channel in trunked mode.

Does it stay a second or two on the control channel, to be able to decode a couple of superframes to check for activity, or it just skip it as if it doesn't recognize the data? If you run it in non trunked mode and have all voice channels in the channel list, will it then stop on conversations?

when in trunking mode it does decode the control channel and it displays basic parameters and even call grants. But it will not stay on the CC or follow the call. Even when it hits the voice channel during a call it will not stay on the channel.

if it's not in trunked mode it stay on the manually tuned channel, it does not scan/hunt and it does not follow the call.

if it's not in trunked mode it stay on the manually tuned channel, it does not scan/hunt and it does not follow the call.

In conventional mode it should scan the channels in the channel list and if it detects a carrier it should at least wait for the time set at t before it continues to scan.

I assume that NEO are something that you compile yourself to get an executable file. Did you get any errors in the log from the compile process? How do you run the program, in native Windows, Linux or emulator window?

I am using a Windows version downloaded from dsd-neo github. I did not compile anything myself.
I don't know if the developer is here on the forum to try to replicate this issue. I have not found anything wrong in using the program, it just does not work in trunked mode.
dsd-fme works fine, so I will be sticking with it for now

I downloaded DSD-NEO out of curiosity and have the same issue as you when trying to follow a NXDN 48 turnked system that I have monitored for years with DSD+. It is continuously scanning instead of following the voice calls. Since I know zilch about this or the FME version I wondered if I was just doing something ignorant in trying to set it up.
