Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
nrsc5
- Nrsc5: Receive NRSC-5 digital radio stations using an RTL-SDR dongle
-
Listen to HD radio with a $30 RTL SDR dongle
That decision was made by the original author (Andrew Wesie), but I think it makes sense because nrsc5 only needs a tiny fraction of the functionality that GNU Radio provides. Implementing the functionality directly in nrsc5 avoids the need for a large and complex dependency.
One downside is that we don't get the broad hardware support that GNU Radio provides, but maybe we'll someday take another crack at integrating SoapySDR. (See https://github.com/theori-io/nrsc5/pull/131 for an earlier experiment with that.)
-
Why does the spectrum analyzer have a square wave by 102.25 MHz, I see the often in FM broadcasting.
That's HD radio, the sidebands are digital audio. It can be decoded with nrsc5 and an rtl-sdr.
-
What is the divergence point of streaming AAC overtaking OTA FM audio quality ?
An article called "Decoding and Listening to HD Radio (NRSC-5) with an RTL-SDR" links to a security researcher's write-up called "Receiving NRSC-5" about how they wrote the software to do it. That links to the actual nrsc5 software on GitHub.
- Square waves in WFM broadcast?
-
Looking for a good AM/FM Radio sollution
There is loads of software that will work such as SDR++, GQRX, CubicSDR, and SDRangel just to name a few. For HD radio reception, there is nrsc5. Nrsc5 only works with an rtl-sdr, so you will need one if you want to receive HD radio.
-
Can I be tuned in to multiple FM stations at once?
In theory could https://github.com/theori-io/nrsc5 be listening to all hd radio at once?
-
Thousands of Mazdas in the Seattle area are stuck on a single FM radio station
HD Radio is closed and proprietary, but there is at least one FOSS receiver out there: https://github.com/theori-io/nrsc5
-
What are these bands to the left/right of the two main CBC signals? Not RDS, but appears to be data of some sort? The FM station at 90.7 and 91.5 are both CBC (French & English broadcasts).
NRSC5 is a decoder that I use. If you are on windows there are a couple of extra steps you have to take compile it, but it works well! They have a newer one with a GUI that can also display album art.

Digital Signal Decode Problem
Depends what version of DSD. The port I use tells you what type of data is being received (not all DMR transmissions carry voice data).
-
Listen to DMR for free
Linux, librtlsdr and this port of DSD. FWIW, this port of DSD is newer and also has a Windows binary.
-
How can we convert a DMR signal into clear voice by RTL_SDR?
In Linux, I use this particular port of DSD - this can be piped into from GQRX, rtl_fm+sox, SDR# or any other SDR software that can output the audio of said signal as raw, 44KHz PCM unsigned audio (mono).
-
Having trouble following tutorial
I'd personally use this fork of DSD, has better TG/CC/DMR ID output... https://github.com/LouisErigHerve/dsd
-
Does anyone in this group use the Digital Voice Decoder, DSD?
I use this particular fork; https://github.com/LouisErigHerve/dsd as it has better output and supports dPMR decoder.
-
Best DMR decoding software.
I personally prefer This DSD client
- 7 strong signals that DSD can't decode. Any ideas?
-
A list of things I could do with SDR
DMR, dPMR, Fusion and more with dsd
-
DMR / Moto trbo basic privacy decoding.
Oh I'm not on about SDR# tools, on about DSD from GitHub; https://github.com/LouisErigHerve/dsd (also supports digital encryption on PMR446). I don't use windows.
- Anyone know any easy ways to listen to NXDN yet?
