I don't notice the low volume issue when listening live, only the recordings and only on certain ones. Mainly "HCEC" Harris County Emergency Corp group transmissions where they will at first sound some sort of "buzzer-horn-alert"- sound before the voice transmission begins. Kind of like an Amber Alert Sound on your cell phone. Live is fine, playback of recording is very low to begin with just after the Horn sound. But I can live with it. Not a real big deal.

I need to learn more about this and if I were wanting to use DSDPlus Fastlane to listen to a Trunking P25 Phase 2 talkgroup. I hate to mess with the file settings and configuration that we have created for the VFD site that I currently pull up. Maybe you just create new files for the new site in question?If you go in your directory and open the groups file, you can give the tg's listed in there the alias to match what's in the db. Alias text goes in-between the double quotes at the end of each line.

If you open the radios file, some NXDN systems auto populate an alias for each radio. They are easy to spot as there will be an asterisk before the quotes as seen here.
NEXEDGE48, 0, 0, 9001, 50, Normal, 1, 2019/10/23 9:56, *"HCEC-1"
If you wanted to give a certain or all radios a permanent alias, you can do so in between the quotes but need to remove the asterisk. So if 9001 was Tower Ladder, it could look like,
NEXEDGE48, 0, 0, 9001, 50, Normal, 1, 2019/10/23 9:56, "Tower 19"
Of you ever do a P25 system, the tg data for p25 can be download in dsdplus groups format.
I have to ask, Cy Fair Vol Fire Dept. P25 system. Is that correct, that the school district has its own police force there? And they operate on a FD P25 system with Jersey Police also?
P25 is different and easier. For that you just enter the control channel and DSDPlus builds all the freqs. Plus, you can download the tg's and sites from Radio Reference. They download to your pc and all you do is copy the data into the sites and groups files. Dsdplus does the rest.
You can by all means keep everything separate by copying the contents of your dsd folder, then create new folder and name it dsd 2 what ever and paste the contents in there. Then just remove all the NXDN stuff from the groups and freqs files, or delete groups and sites and replace with what you just downloaded. Just like starting over.
Then if you wanted to try a smaller P25 system, start with maybe this one Houston Independent School District (Project 25) Trunking System, Houston, Texas

I actually have a few DSDPlus folders and also use multiple pc's at the same time and use Teamviewer and Onedrive.

Pretty neat Dave. I've been playing around with it. I did make an exact copy of my original folder. DSDPlus 1p101 called it DSDPlus1p101-p25. Removed all the NXDN Stuff. Checked decode P25. The Houston Independent School District map shows tower/towers range outside my area since I'm in Atascocita, Harris Co, Texas. I just put in a cc from RadioRefference and it started decoding. I need to play around with it but beginning to see the capabilities of this DSDPlus program. Is it possible to setup 1 particular Talkgroup on a simulcast site, without having to hear all the traffic on that simulcast site? On SDRTrunk you can just "Mute" the talkgroups you don't want to hear. I would probably need to use more than one dongle?

Two ways with the latter being the quickest but all dependant on your long term preference for that system.
After you have downloaded all the tg's in the DSDPLus formatted tg's in the database, and paste it into your groups file, open it up and use either notepad (Windows) or Notepad++.
This is from my groups showing a normal tg that will play vs a tg thats locked out. Just change the Normal, to L/O,. If you have OCD like me, and want to keep all your commas in a row, I believe it's 6 spaces before L/O, . Fastest way to use this method is to use find and replace in either program mentioned above. Find Normal and Replace with L/O. Do them individually on every tg you want to block.

Or, the fastest way, set the priority of the tg's of interest to like 60. then when running DSDPlus, click in its window to focus. Hit T or t to adjust the monitoring threshold.
T/t Adjust voice monitoring threshold
Default is 50, so any new unknow tg's detected will operate at 50. So if your on 60, and there is a new tg, you will not hear it. So if you have interest in hearing any new tg's on the system, the first method above would be the better option. Others may have other suggestions as well but that's how I handle those.
Capitol T goes one way and lowercase t goes the other.
Thank you Dave. I'll study your suggestion awhile and see if I can follow your instructions. slow process for me. 70 years old and a mini stroke 3 weeks ago but I'm bouncing back pretty quick. I appreciate your patience.
These are all the active DSDPlus keys you can play with after clicking the DSDPlus event window. If you play with B, it gives like 4 different choices as far as what it will display so if you have no interest in seeing every radio that affiliates or leaves a site, you have that option. You can also have it not display anything lower than the threshold you set for your tg's of interest.

If I just wanted to listen to one particular Talkgroup on a simulcast site could I do that by using the IR Channel Activity window and clicking on the Talkgroup when it appears in the window and putting it in HOLD mode? Or spacebar. Would this block all other traffic except for what was on HOLD?
I don't usually hold on tg's but just tried with the spacebar and it seemed to work. I usually use the threshold settings. Today I trying to clean up my dsd directories. To many unfinished projects over here..
I like to listen to the specific Constable Precinct # Talkgroup that patrols my neighborhood and area. Hold with spacebar seems to do the job. Appreciate it Dave and good luck with that cleanup.
If there is a possibility that you might want to hear other traffic, I would use the priority to single out the one talkgroup. For example, set it for Priority 5 and others above 20. Set your threshold at 10 and you would only need to bump it up above other groups to hear them.
The problem with Hold is that you need to have the group active or hand edit the Groups file.

With SDRTrunk, on a P25 Simulcast site where the frequencies involved would require 2 dongles to cover it all, shouldn't the same be required with DSDPlus Fastlane on that same P25 Simulcast site? SDRTrunk seems to automatically load all of the dongles plugged in and uses them as needed. How would you use and setup the DSDPlus Fastlane program for the second dongle? Appreciate it, still learning DSDPlus Fastlane but definitely liking it so far! Also not real clear on the DSDPlus.frequencies file. Should all of the frequencies listed on radioreference for a particular Site be added to the DSDPlus.frequencies file? Normally about 4 or more frequencies one being the CC which changes from day to day on some sites, and by doing that what does that allow the program to do? Automatically search those frequencies for the control channel on startup? Appreciate it

If the site spans 2.4mhz or less, you can use one dongle. Unless your using an airspy or sdrplay which cover larger areas of bandwidth. I have nooelec dongles and run them @ 2.56mhz in sdrtrunk. I also have my airspy mini in there running at 6 mhz covering two systems simultaneously.
Sdrtrunk stays tuned to the control channel and allows any voice channel within that 2.4mhz to be heard. Dsdplus monitors the cc for activity. When it sees a voice grant on another freq, the dongle tunes to that freq for the duration of the call. When the call is done, the dongle returns to the control channel. I was on a site the other day listening to voice calls that were 5 mhz away from the control channel.
The fmp24-cc bat file basically opens a dongle (numbered by default)(which is why I use i0 which will open first available dongle) and sets a tcp port for it to output on. Then the 1rbat opens dsdplus for that same port. Second dongle is a copy of the first bat file just with a different port set to output. I have run a total of 4 instances out of the same directory at once. I really need to set up my second monitor again.
P25 freqs do not go into that file as those are all managed but the program. All other digital freqs do go in the freqs file.
