The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

What Sat's can i recive in the 137mhz range? I got noaa 15,18,19 working and got some images. I know that METEOR M2 is basicly offline. are there some other sats i could try, or even in higher frequencies witch i can get without a dish setup?
If you do want to give amateur radio satellites and/or cubesats a shot, there's a whole bunch of these that transmit a bunch of different stuff. Most of them transmit telemetry, or amateur radio stuff, but I know there have been a few that have transmitted SSTV images or even pictures from onboard cameras. Satnogs is a great resource for these spacecraft, since they have an excellent database and a forum full of info. I've always used gr-satellites, which is part of the GNU Radio ecosystem, to receive these satellites. Fair warning, though, these satellites can be a bit tricky to work with. For one, GNU Radio isn't always the most beginner-friendly software to get set up. And some of these satellites, especially the cubesats, just don't have the strongest of signals.

Upsampling in Gnuradio is necessary?
In gr-dtv transmitter examples for Gnuradio, I see some times people use a resampler block before the RF hardware sink. Say our sampling rate is ~9.14Msps which satisfies the Nyquist criterion because our samples are complex numbers.

Capturing FM using SDR
2.1. Thanks for that tip, I forgot that I was able to check the source code of the WBFM Receive block. As you have said, there are mostly the same. There are some differences between how values are picked. The WBFM Receive block would be a synonym of Quadrature demod => Fir Filter (decimation => Low pass filter) => FM Deemphasis. 2.3. My question there is why 10 and not 20 or 100. I understand that the idea is to reduce the sample rate asap, but what I don't understand is why those values were picked and how can I understand what would be the "correct" or "best" value. 2.4. I'm not fully understanding what you said. If I check the WB FM recieve source code the values that are supplied as the cutoff freq and transition width of the Low pass filter differ from the one of the example. The webfm would apply a sample rate / decimation / 2 - sample rate / decimation / 32 as a cutoff freq and a sample rate / decimation / 32 as a transition transition width. Calculating those values would end up in different that the ones supplied in this second example. Again, is there a rule of thumb to pick these values?.
- Hello everyone! I would like to install and run GNU Radio version 3.7.4 in order to follow along with The HackRF GNU Radio tutorial on greatscottgadgets.com/sdr/ but I can’t find prior releases to install. Can anyone help?

Multi band gfsk demodulation with Nooelec RTL-SDR v5 SDR and gnu radio
Gaussian filter is used only on the tx side, so specifying bt in the receiver makes no sense. Take a look at gfsk mod/demod blocks implementation: https://github.com/gnuradio/gnuradio/blob/master/gr-digital/python/digital/gfsk.py

Is there a way to delay a signal in time-domain?
Here's the filter coefficients used for the GNU-Radio interpolator block to get you started. This is a 7th order interpolator (i.e., 8 FIR taps) with very good performance. Each "row" of the array sets the delay in steps of sample_time / 128.

My grandpa is a huge HAM radio fan, so I showed him GNU Radio. Got this text the day he got back home.
From their README: “open-source software development toolkit that provides signal processing blocks to implement software radios.” https://github.com/gnuradio/gnuradio
