None of the files have been changed except for fmpcc.

Run cc. Run FMPvc. Run vc. The FMP window for the control channel is showing the signal strength etc but the 2nd FMP window is not tuning to any frequency when a talk group is active.

I'm also not seeing any of the small blue windows that show the audio signal. I've followed all the instructions on downloading all the required files. Although for a P25 system I followed these steps:.

Joined Jan 6, Messages The good thing about P25 for us radio enthusiasts is that the information and frequency for the voice channels can be calculated from data sent out by the control channel.Forums New posts Search forums.

Voice channels do appear in the event log, but I would like to get an history of CC and SCC frequencies when I am monitoring new sites.

That would be really useful for new sites identification. Thanks, Tikev. Per the notes. D66 Current site: Last edited: Sep 5, Your frequencies can be found in the dsdplus. I was assuming you were using DSDPlus as an -rc instance and an -rv instance for following the site. If running normally it may not show P25 CC's.

I'm new to the fastlane, So I'm sure others may have better wisdom I love it though! I believe it is in the log. You just have to find the right one. Check every log and event file it's there unless it was erased or logging was never started. I want to know if I can have it somewhere in my logs instead of making a print screen every time I want to save the data. You could also look at Unitrunker, it has a special window which displays every site frequency and the number of hits associated with each frequency.

Open the new file with notepad. Copy the line below here everything but without the quotes.There are multiple versions of the USB SDR, but this is the straightforward way to get the device working for digital trunking systems. Note: These instructions do not include steps to decode encrypted radio communications.

It was discovered that the modification typically allowed moderate reception of frequencies between 50 MHz to 1. Before we continue, there are also many questions about shortwave receive. Other systems can also be tracked. This is a simplified guide of how to use one dongle to trunk digital radio systems in the UHF band. The device requires special drivers and software that must be configured in order for this to work.

You can expect about 15 minutes to half an hour to get up and running. In addition, this guide is for a Windows system only.

Linux based systems may differ in setup. Setup typically requires administrator privileges.

Ignore any information about drivers failing to install. The driver should be listed as WinUSB 6. If you successfully install the driver, then close the driver installation software and go on to the next step. Download the latest version of Unitrunker. Install it to your computer. Run Unitrunker and select the plus sign to add a new receiver. Next, copy the configuration settings in the image below. You will see talk groups, which means your software is properly working.

This is the digital voice decoder software. Be sure to use the latest version. You will also need to go to your audio control panel and click on recording devices.

Set the VB cable device to be the default recording device. Wait a few seconds for talk groups to appear. Change this value, until you get it working!

Thread starter EricCottrell Start date Sep 9, Status Not open for further replies. EricCottrell Member Database Admin. There is no defined control channel and a slow rate data steam SACH is used for control information.

Very dry reading. There are three types of systems possible with IDAS, a single site system, a multisite system linking mutiple sites together, and a intersystem system linking multiple mutisite systems together. Site Ids have a range of 1 to with reserved values of 0 and to LTR style Repeater numbers are used with a range of 1 to LTR style radio ids are used with the home repeater portion replaced by a subgroup prefix with a range of 1 to This is tied to a home repeater on single site systems.

The prefix of 0 is used as a filler or to indicate a user from another system on a intersystem system. The group portion has a range of 1 to for normal groups with 0 used as a filler. A home repeater will send a burst of data every 2 seconds or so. It is quite sparse on a single site system with just an Idle message. A site in a multisite and intersystem system will send the Site Id and Adjacent Site information. A multisite and intersystem site will also have a collect repeater that will send a burst of data every 2 seconds or so.

The main traffic on the collect repeater will be registration of radios as they roam between sites. Voice traffic can be carried on the collect repeater if all the other repeaters at the site are busy. DWR messages are used.DSD for Raspberry Pi. Attach Keyboard and USB sound card 5.

This is why I love open source software and include code for unfinished formats so others can tinker with them. I am still waiting on confirmation that the ProVoice EA sync added in version 1.

No comments:. Labels: DSD 1. I did this as a stop gap until the big players have come up with something. And in true SDR form, here is the setup. Java program to decode DMR. Just a quick announcement of a little project I have started work on. I was fascinated by the release of DSD whoever the author is if you are ever in the UK I owe you a beer but I'm only really interested in the DMR decoding side of things as we hardly have any P25 over here. So I have taken parts of the DSD C code and ported it to Java with the eventual aim of creating an open source DMR data side decoder I'm leaving the voice side and its legal problems alone.

The NXDN control channel sends out data that tells subscriber radios to, for example, switch to channel The actual frequency isn't sent out on the control channel.

For the TRX scanners, you just enter the frequencies; there's no provision to enter what channel number goes with which frequency. Last edited: Dec 16, Hi Ken, Ditto. Well, other than the great audio quality, there is no comparison.

I have conversations dropping in mid-stream, picking up in mid-stream, being missed altogether, and dropping when the programmed delay should be picking up the next transmission.

This is a 4 frequency system. I even locked out the remaining 28 unprogrammed frequencies for the site. I'm using a talkgroup wildcard. Joined Nov 28, Messages Location S. Bay Area. Same thing here in the S. I haven't heard both sides of a conversation yet. I hear more when locked on the Wildcard, but still only one side. I"m hoping future updates will correct this.

AggieCon Member. Joined Nov 25, Messages 1, Location Texas. If you have only digital objects on the scanlist, try lowering the squelch all the way and see if that helps. The delay might actually be hurting you too.

I'd set it to maybe. Try it for awhile with just one ideally quite active frequency in the site details window. Leave the squelch all the way down. With it like that, are you hearing the entire broadcasts? Basically, it's a test to see if the scanner is bogging down checking too many frequencies with a long dwell time.

I have 7 sites programmed.Forums New posts Search forums. Media New media Search media. Classifieds New listings. Log in. Search titles only.
