I can't remember the last time I bothered to comment on a KZbin video but I wanted to say thank you for an extremely accessible introduction to GNU Radio and - most of all - reminding me that I can set values to declared variables instead of tweaking the entire GUI constantly.

[@LocurasPreepers]

Dear Sir, could you record this video, showing the inner parts of the mechanism, this is the title of your video "Recreating a 16-Bobbin Rope Braiding Machine" I hope you can read this message, best regards

[@kodrawer]

Al, thanks for another very helpful GRC video.

[@RichardKCollins]

Thanks for the videos on GNU Radio. I spent a lot of time with SDRs trying to get data from them. Did not know about GNU Radio Companion. I happen to live in Houston. Thanks

[@stag143]

best tutorial since i'm learning grc thanks es 73

[@Akshay-cy9tu]

That was just wonderful

[@josevicentelopez3151]

Very helpful but I missed the step by step like the first video... this one is only for look what you can achive with the GRC, but still awesome

How can i use this GNU radio for AM for the VHF and UHF Frequencies

How i can use AMITRC SDR for AM in VHF and UHF Frequencies

[@kotai2003]

Very nice tutorial. especially on QT GUI.

[@SetMyLife]

Nice. How is it that your PC had no trouble processing the 2MHz stream?

[@user-tb9tw5fp5v]

Where are the other parts ??

[@skidmoremusictech528]

In March of 2020, the Osmocom source is gone in GnuRadio Companion. What do we use instead?

[@davewalker7126]

Great starter tutorial - I'm already building simple radio projects thanks to you, even though the tutorial is many years old. It was well woth watching just for the initial get going first steps. I guess what would be nice would be the ability to turn a project into a stand alone executable without needing to run companion - not sure if thats ever to be a feature

[@masalakinkela4940]

Hello Sir, would you please tell which do I need to create a GSM Tx signal

[@maximus6884]

Need more

[@jimdarrough1732]

Nice explanation. Wow there are a LOT of things one can do with Gnuradio! Kind of makes me want to dig around and find my old SDRplay dongle. What Linux flavor were you using?

[@AjayKumar-lc9pv]

Bro can u say how to dpcm using gnu

[@robertterzi4451]

I appreciate the effort that went into this. However, there are a couple of problems with this video 1) Too much time is spent showing and discussing the options slowly instead of explaining key things. 2) A minority will have an SDR that goes down to 15 Mhz or 1 Mhz as shown here. Most will have RTL-SDRs that only go down to 24 Mhz. It would have been better to show FM Broadcast which would be accessible to a wider audience. I recommend Michael Ossmann's SDR with HackRF tutorial series on Great Scott Gadgets. A HackRF isn't required for most of it. You can follow much with an RTL-SDR as long as you use 2 Mhz sample rates (or below. (The RTL-SDR generally tops out at around 2.4 Mhz sampling compared to the 20 Mhz that the HackRF can do.)

[@JoannaaHon]

I don't find 1) to be much of a problem than it is a personal opinion. I personally prefer the detail that was included when explaining different options

[@MaaveMaave]

My RTL-SDR Blog V4 can just barely listen to AM radio. I mostly followed this guide and received a scratchy 14 kHz AM radio station. FM is my next step

[@MilanKarakas]

Not working with RTL SDR...

[@SefiMerkel]

I have installed the GNU radio under my Windows, and couldn't find a way to connect my SDRPlay box. can you give me a hint?

[@kodrawer]

Hi, Sefi. Have you ever found a way to get sdrplay to work with GNURadio under Windows? I just got an sdrplay RSP2, it works fine with SDRuno, but I cannot get it to work with GNURadio companion. Any help would be appreciated! Thanks.

[@KustovEvgen]

I have exactly the same problem. You managed to solve ?

[@CocolinoFan]

This Part 2 is soooo much worse then Part 1. In what blocks are those variables put? for example.... I am finding it very hard to follow.
