VB cable was the problem, got rid of it and installed Virtual Audio Cable, completely redid everything and it works flawlessly! is there a way to separate this, where once voice dongle will only follow the EDACS dongle, and the other voice dongle will follow the P25 dongle? Looks like it should be working. You should link the the authors website instead, http://www.dsdplus.com/. The biggest feature many have been waiting for is the ability to import talk groups for their radio system into the application from radio reference. This version is dated 07/27/2001. sdrtrunk v0.6.0 Alpha 5 releases: decoding, monitoring, recording and You will require a decent antenna that is capable of receiving the trunking frequencies you are interested in. The copy of DSD+ stored at ZippyShare appears to have a virus. UniTrunker - The RadioReference Wiki I have survived some terrible injuries and got thru cancer 3 times, so far, n really could use an edge on survival. A java-based application for decoding and listening to trunked mobile two-way radio systems and related radio signals using one or more Software Defined Radios (SDR) tuners. The application provides local monitoring of decoded audio, recording, and streaming of audio to local and remote streaming services. This will open up several windows. Basically this allows you to tune and monitor to multiple control channels with a single dongle, as long as they all fit within the dongles bandwidth. I finally found a signal freq in the 770mhz band that did show all channel freqs. Unitrunker can be used to decode the control channel and follow a voice conversation as it hops across various frequencies. This will mute the control channel audio. Nightly Build. The authors write: This applications sole purpose is to allow Universal Trunker (aka Unitrunker) to control the tuning frequency of individual VFO's in SDR Console v2. Mike. Mototrbo is not supported only Motorola trunking systems. Over on YouTube user AVT Marketing has uploaded a five part video series that very clearly and slowly shows how to use an RTL-SDR to set up trunking and digital voice monitoring. This allows the frequency spectrum to be shared, instead of designating one fixed frequency peruser which would be very inefficient. For the RTL-SDR this should be within about 2.56 MHz of bandwidth. The RTL-SDR can be used as a wide band radio scanner. The biggest feature many have been waiting for is the ability to import talk groups for their radio system into the application from radio reference. Compared to Unitrunker SDRTrunk is an all-in-one package, and currently it supports most trunking system control channels, but unlike Unitrunker it still misses out on some systemsEDACS and DMR. If it is below 100 it may indicate reception problems which will need to be solved by tuning the signal correctly, adjusting the gain, or using a better antenna. The second video shows how to install an RTL-SDR, and walks you through downloading Unitrunker and DSD+. . Note: We will be usingan extremely popularonline site(RadioReference.com)to find the control channels for our location. GitHub - DSheirer/sdrtrunk: A cross-platform java application for The RTL-SDR can be used as a wide band radio scanner. This is because in a trunking system the frequency in use during a conversation can change often. RX6) are tuned to the voice channels. In the new window that pops up choose your first RTL-SDR under RTL Device. Fast forward a few years and the software has seen numerous changes. What follows below is a tutorial on how to set this up. Website: - DSheirer/sdrtrunk github.com Scroll down to 6. This page was last edited on 26 November 2022, at 13:52. Trunking Recorder will also queue up recorded calls so you never miss any . Can this be done with just one wideband radio? Only one trunked system at a time and no you cant scan multiple frequencies alone. Doubt I can make it thru the next big thing medically. Id be willing to host DSD+ on this server, but only if I got the authors permission. The control frequency was in error by 1MHz. It may interest ham radio enthusiasts, hardware hackers, tinkerers and anyone interested in RF. He also later explainshowthe Airspy can be used instead of multiple RTL-SDR to cover 10 MHz of bandwidth so that multiple systems can be monitored. Yes it can help find a new trunk system. The channels that are displayed in green are the allotted frequencies for a given Talkgroup (an assigned group on a trunked radio system). So close to working. It is also Java based so it is cross platform and so can be used on Linux and MacOS systems as well. However, checking this with SDR Sharp shows the frequencyneeds to be857.1375MHz(shifted down by 100KHz). As I mentioned I have my signal channel working (it appears) and I am able to view Joins and Calls but I cant hear anything tried adding DSD+ to the mix but it seems like Im just not getting the listen channels correctly. It is also Java based so it is cross platform and so can be used on Linux and MacOS systems as well. Great write up. SDR related questions should be posted in the Software Defined Radio forum. However, this is very inefficient as the frequency may not be in use for the majority of the time. So if someone (s) in your world can help us I would greatly appreciate it and it could actually be the difference in a huge way. Most excellent, thanks for the write-up have it up and running total time for upgrade from single dongle with SDR# and old UT along with Freescan and serial attached scanner was about 20 minutes most of the hassle is making sure the RTxxxx driver doesnt install and screw things up, and then trying to tell which dongle was which (my nooelec is much better than my other generic one not sure why using the nooelec for control and the other for voice). Change the VCOs setting to 2 VCOs, or however many you want. All release versions of sdrtrunk are available from the releases tab. Im not anybody special and what I signed up aint the gig with the big bucks just 1 overly patriotic/gungho dude tryin to make a difference.

Not sure what Im doing wrong but help would be awesome! Followed the single-dongle instructions and I am not getting anything on the 2nd VCO. APCO Project 25 - The RadioReference Wiki The sections covered include, installing Java, setting the Java environment variables, installing other SDRTrunk prerequisites such as Apache Ant and the JMBE audio codec for decoding P25, and finally actually using and setting up SDRTrunk. Note: I chose the unskinned version of SDR Sharp version for this demo. See the. With the proper amateur ham license, can one create a trunked system (using an open source voice codec like Free-DV)? Use this plugin to allow Unitrunker to control SDRSharp, so you can listen to trunked radio conversations. 1. It cant open the device if its being used by another program. yet so far away. But the 2nd VCO and scope never display anything at all. no radio selected. Shoot somehow i new i needed two dongles oh well guess it will be another week or two. Whats the matter? channels manually entered and working fine. I frequently visit this site since 2013. The end results is that I could only record about 3 channels at once before the CPU got overloaded. Once you have the system running to improve performance we recommend disabling Auto Gain and instead setting the gain manally using the Gain entry under the Info tab in both the Signal and Control RTL-SDR options. Support can be found on the Voice Control Channel Decoding Software Forum. sdrtrunk is released as a stand-alone application bundle that does not have to be installed. Where would -YOU- suggest making it available? It is similar to Unitrunker and DSDPlus combined into one program. The SDRs capture large swatches of RF and then use software to process what was recieved. If you have unencrypted TETRA signals available in your area it can be used to listen in on them.
