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: 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.

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.

From https://github.com/markjfine/nrsc5-dui#maps :
> Maps: When listening to radio stations operated by iHeartMedia, you may view live traffic maps and weather radar. The images are typically sent every few minutes and will fill the tab area once received, processed, and loaded. Clicking the Map Viewer button on the toolbar will open a larger window to view the maps at full size. The weather radar information from the last 12 hours will be stored and can be played back by selecting the Animate Radar option. The delay between frames (in seconds) can be adjusted by changing the Animation Speed value. Other stations provide Navteq/HERE navigation information... it's on the TODO 'like to have' list.
Is this an easier way to get weather info without Internet than e.g. Raspberry-NOAA and a large antenna?

NRSC5 no audio - linux mint
and sometimes I use https://github.com/markjfine/nrsc5-dui when I want to see the weather and traffic maps . honestly they are worse quality compared to the weather network for local coverage but it is a neat demo

A New and Good Program for HD (NRSC-5) Radio
After a lot of searching and testing I came across the developer Markjfine and after trying to make nrsc5-gui to work well he decided to fork the project to nrsc5-dui. Nrsc5-DUI is a fork of a really old version of nrsc5-gui that is not dependent on python audio processing which caused a lot of issues with modern versions of nrsc5-gui. Like the old version, it still uses python, it's still licensed as GPLv3, and has a similar interface. However, Nrsc5-DUI has plenty of new features and improvements such as better audio processing, better channel switcher, more station information, the option to pull album art from Discogs (currently broken due to Discogs anti-bot), better map displays, cleaner code, and optimizations for Python 3.9.
