It is relatively simple to use compared to other SDR software and has a simple set up procedure. We have a full overview of the installation procedure on our Quick Start Page. SDR is a simple to use program that also has some advanced features. It has a useful modular plugin type architecture, and many plugins have already been developed by third party developers. The basic SDR download without any third party plugins includes a standard FFT display and waterfall, a frequency manager, recording plugin and a digital noise reduction plugin.

The official installation instructions can be found here. Users will also find an Audio FFT and waterfall display on the bottom of the screen. The output audio can also be bandpass filtered by dragging the filter borders on the display. Bandpass filtering the audio can really help clean up a noisy signal.

The audio processing also supports placing of notch filters either manually or automatically. Traditional ham radio users will also enjoy the S-units signal strength meter and the built in frequency manager. Be sure you install version 2 and not V1.

To compile your own dlls see the instructions hereotherwise download the dlls directly from the bottom of this link.

Built in are also several DSP features like a noise blanker, noise reduction filter, notch filter and squelch options. The EMNS noise reduction filter is particularly good at automatically cleaning up and clarifying voice signals.

Furthermore, sdr-radio V2 not V3 yet has an excellent remote server which will allow you to easily set up and connect to a remote RTL-SDR server over a network or the internet.

Finally, sdr-radio is capable of listening to up to 6 signals in the same chunk of visible spectrum at a time. Many users prefer to use Linrad as it can be set up to have a very high amount of information density on the screen and it also has an advantage with receiving signals with the E tuner as it can be made it run in a special linearity mode which significantly improves the dynamic range. Linrad also has some very advanced features not found in most other SDR receivers.

Linrad is probably the software most superior in terms of actual signal processing performance. To install Linrad on Windows first download and run the setup-dll installer, and then download and extract the actual Linrad program.

You will need to go through a text based set up at the very beginning. It is similar to SDR in terms of features and simplicity of use. It is essentially the same as Studio1. Since ShinySDR is controlled via a web interface it can easily be controlled over a network or the internet.

It also has a plugin type development feature which allows demodulators to be easily written and integrated. The current main technical advantage to ShinySDR is that it has a persistent waterfall, meaning that the waterfall can be moved, zoomed and re-tuned without loss of any history like in other SDR software. The WebSDR system allows for multiple public users to connect to a radio over the internet and tune to various frequencies.Forums New posts Search forums.

Now to the question. I have been using DSDPlus to decode voice calls but is there a possibility to decode the sms message. I know the voice calls are saved in. Any help regarding this would be very much appreciated.

Once again thanks for every thing. Joined Dec 19, Messages I think dmrdecode does some SMS decoding if I remember correctly. Thanks Dude. Joined Dec 13, Messages Just copy the whole thing to clip board and paste it in any of the online binary to ASCII converter like the one below.

Binary to Ascii Text Converter You will have some padding bits and once you remove them you will get your actual message. SignalPatcher Member.Digital Speech Decoder is an open source software package that decodes several digital speech formats.

It uses the mbelib library a separate open source package to synthesize the decoded digital speech.

It does not allow decoding of encrypted communications. It can save the compressed digital audio bits to "mbe" data files. It's discussed in this forum. Any linux distribution should work as long as it has support for your audio devices.

DSD version 1. The forum for discussion of this package can be found here. This means that as far as copyrights are concerned it can be freely copied and used, including for commercial products as long as the original copyright notice is included.

However, see important patent issues section below. While DSD was intended to be patent-free, mbelib describes functions that may be covered by one or more U. The source code itself should not be infringing as it merely describes possible methods of implementation.

It is unknown if DVSI will sell licenses for software that uses mbelib. If you do not have a license and are in a jurisdiction protected by the DVSI patents you should not compile or use this source code.

If this list gets large enough I will move it to its own page so as not to detract from the overview of DSD. A: Yes, if you want to listen live or save mbe data files, and are using a scanner for input. No radio or discriminator tap is required to play saved mbe data files. It should be easy for someone familiar with Mac audio programming to port it to the Mac.

The RadioReference Wiki. Category : Software for Signal Analysis and Decoding.Voice frame. As it suggests this contains digitised voice data in two bit sections separated by a 48 bit synchronisation sequence which identifies as the frame as being a voice one.

As yet the program does nothing with voice frames other than displaying their presence. Data frame. These contain signalling information which is required for call set up. The frames consist of two 98 bit sections which contain the main signalling payload which the program doesn't yet decode plus a 48 bit synchronisation sequence which identifies the frame and a 20 bit SLOT TYPE section. A decoded example would be. Where you see the systems colour code actually a number between 0 and 15 and what kind of information is being sent in the main signalling payload of the frame in this case CSBK data.

Again we see the systems colour code and what type of information is contained in the embedded field in this case the first fragment of an LC. This example tells us that slot 1 us active with a voice group call which has a shortened address of while slot 2 is inactive. Skip to content. Decode Jump to bottom. DMR data is arranged into frames each consisting of bits. There are three types of frame. Embedded frame. These frames don't contain any synchronisation bits but instead carry embedded signalling in its place which isn't currently decoded they also contain either voice or signalling data in their main payload.

General scanning discussion forum. Is there any software around that decodes the DATA side of the transmissions aswell as the voice? Its the latest version of DSD for decoding digital voice transmissions.

Are you asking "What is DSD? You connect your scanner Disc Tap Preferably to the audio input of your PC and the with a little bit of tuning, DSD will let you hear the decoded audio.

It decodes a few digital modes. It also does P If your new to scanning and this type of software, let me know and ill point you in the right direction in respect to learning.

PM me Bud. You must have heard of DMRdecode before! Its a brilliant program, uses java. It shows whos calling who, if its a group or private call, the colour code. And also it can show the binary for any other data sent, such as gps info.

Digital Speech Decoder (software package)

It doesn't decode gps yet, don't know if it ever will.A good antenna system is the basis for all radio comms. Once you have SDRSharp up and running then please revisit this guide.

A quick bit of background about this plugin. I found this nifty plugin after a few hours of searching the internet. To install this plugin simply extract the SDRSharp. Next you will need to open up the SDRSharp plugin file called plugins. To verify the plugin has installed you can now open up SDRSharp. If you cannot see the DSD Plugin then you may need to install one of the newer net framework packages. At the time of writing this is DSDPlus1p Once downloaded you will need to extract everything from the DSDPlus1p Once you have copied over the contents of the zip file to your SDRSharp install directory, you can proceed on to step three.

To do this you should download the lamemp3 dll from here at the time of writing this is available as libmp3lame-win Once you have downloaded the lame mp3 encoder, you will need to extract the lame mp3 dll into your SDRSharp folder. In order for you to get your audio where it needs to be i.

You can set the sample rate of these virtual cables to if you wish. The first thing to do is to start up SDRSharp. A new window should open up as shown in the picture below.

At the top of the new window, click where it says DSD Path click to edit and another window will open up. Here you will select your Virtual Audio Cable from the drop down.

Now a bunch of stacked windows should suddenly open up in the top left corner of your monitor. You should now see something that looks like this:. Every computer system is slightly different so you may need to play around with the audio routing to get things just right.

Usually This and a couple of other useful settings can be found in the FTT Zoom plugin and you enable them by checking the check boxes for each option. You can also fine tune using the IF window to get the signals centered correctly. When DSD first starts up it tells you what audio devices are available and which ones it is using. Looking at the DSD window when it first opens up you will notice a bunch of reports on audio devices. The first 4 or 5 lines relate to what devices are available.

You can verify that the audio is going to the right place using the Audio Indicator window which opens up with DSD. No signwave, no audio. One for the Input device and one for the Output device. The device numbers are listed in the DSD window when it first starts up as shown in the previous screenshot.

Both are capable of monitoring P25 Phase 1 and Phase 2 systems and are the first consumer-grade scanners based on software-defined radio SDR technology. Instead, the user manipulates a simple, iPod-like front panel interface. Uniden is selling the HomePatrol-1 scanner, which requires no user programming. Scanning is based on the entered zip code of the user. Uniden is selling the BCXT scanner, which appears to be similar to the BCT with the addition of several features, including a bandscope, control channel data output, GPS location-based scanning and the ability to track systems that use ESK.
