    I'm just getting started with GNU Radio. and besides the official tutorials please share any other good tutorials both written and videos.

    At the moment I have a FUNcube Pro dongle and a Softrock set up for the IF output of the K3. I'm not exactly sure what I'll be able to do with either or both beyond what already exists out there, but I'm sure it will be interesting to learn.

    I'm the developer for the Digital Television component of GNU Radio, so I'll plug it a little bit here. The author of Gqrx, Alexandru Csete OE9AEC has used the GNU Radio DVB-S2 transmitter to provide video from an amateur rocket launch.







    Here's where he's just starting with DVB-S2.



    This is just an example of what can be done with GNU Radio. The possibilities are almost limitless.

    I have a Lime SDR, HackRF, Ettus B210 clone, SDR Play (original before it was a one), NooElec RTL and a few generic RTLs. I have used GQRX with the NooElec for monitoring APRS. I have used SDR Console with the Lime, HackRF, SDR Play and the Nooelectric.

    The only way I was able to get the Lime SDR to do anything was with SDR Console. The software from the Lime SDR manufacturer wouldn't do anything except crash. I tried the Lime SDR in Linux and Windows 7 and 10. I was even toying with selling it as I have lost confidence in it working. I was part of the support forums for a few months and everything I tried didn't work. Mean time, the GURUs were demonstrating how it worked as a Cell Phone repeater or some other non-ham function. Its gathering dust.

    I sprung for a Ettus B210 clone that I would like to see work. Its recognized as something else on the USB port and the usual software won't touch it.

    Yes I am interested in GNU Radio...

    You have to bootstrap an Ettus B210. When you power it up, it identifies as a Cypress USB 2.0 controller. Then you have to load the FX3 USB controller firmware to enable USB 3.0. Then the FPGA needs to be loaded.

    It's all done automatically with the Ettus driver called UHD.

    Since I'm a developer, I always build from source. But I realize folks have trouble with that. I believe you can just apt-get UHD, but I've never done it that way.

    If you're willing to build from source, I have a recipe that works well for Ubuntu.

    My most popular GNU Radio application is an OFDM spectrum painter. It paints an image into the waterfall of a receiver. By using a large bandwidth (2 MHz) and many carriers (4096), it's possible to paint a very detailed picture. This is a hacked version of Gqrx where I changed the waterfall colors to a slightly blue tinted black and white.

    Here's a video of it in action.

    This is some scary stuff, I have spent the last hour trying to get to the point were I can do something with the directory I cloned. I cloned something to something but cant find where I cloned it.

    I assume you mean "git clone"? It just creates a directory in your current directory. For example:
