The whole world goes wireless. And digital. One technology is right in the center of these two megatrends: Software Defined Radio or short: SDR. Do you know how it works? And how you can take advantage of it? If you do not want to take the time to watch Michael Ossmann's (Great Scott Gadgets) series, then this SDR tutorial is for you Software-defined radio is a relatively new technology and was extremely expensive in the past. Then came this small USB dongle for 10$ and changed all. And other, more capable devices like the HackRF One for 300$ pushed this technology into the mainstream. Today, most modern radios used for example in Smartphones, in Amateur radio equipment, or Satellites are SDR radios. This is the reason for the tutorial. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, and others. #SDR #Tutorial #Electronics My HAM radio channel: 🤍🤍youtube.com/channel/UCQwyP4Yd0-O49e05kMUJgQQ Links: HackRF one: 🤍amzn.to/3ei2gQn Clones: 🤍bit.ly/2ZEe3Df or 🤍s.click.aliexpress.com/e/MnOHFW5w RTL-SDT V3: 🤍s.click.aliexpress.com/e/B08cnKey RTL-SDR Dongle: 🤍s.click.aliexpress.com/e/_9QvOSo (RTL2832U , R820T2 ) Pluto plus (better): 🤍s.click.aliexpress.com/e/_9G4To5 Original Adalm Pluto: 🤍🤍analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html SDR-Play: 🤍🤍sdrplay.com/ Lime SDR: 🤍🤍crowdsupply.com/lime-micro/limesdr Ettus Research: 🤍🤍ettus.com/ SDR Intro by M.

xQVm-YTKR9s&t=17m26s 17:26 on the board: Why did you choose a Hamming-Window with the Lowpass Filter? Would a eg Blackman Window make more Sense for a more cleaner Signal in respect of harmonics?

Great Video.

this is amazing video! ive been using SDR for 3 years not really knowing anything about them haha thank you!!!! 73 ! W0NLB

Wonderful to find someone who really knows what they are talking about.

Interesting side note: in North America where HD Radio is used as opposed to DAB and DAB+ (whose spectrum intersects with TV channels 7-13), a market with a station at 100.7 FM will have two more plateau-shaped sidebands where the IBOC signal appears to the left and right of the analog carrier, by as much as 100 kHz. Also, multiple subcarriers can be present in the analog carrier: the stereo subcarrier at 19 and 38 kHz, the RDS subcarrier at 57 kHz, and two more subcarriers at 67 and 92 kHz for subcarrier audio.

I am so glad I am getting into this now as opposed to 5+ years ago. There is just sooo much more content about this available to noobs! Thank you for making this!

Thanks for all your great videos. You do an outstanding job of conveying dense subject matter without anesthetizing your listeners.
Your list of SDR hardware is a very helpful place.
I wish you’d revisit Analog Devices ADALM-Pluto. Your description was correct however didn’t tell the whole story. For example, the frequency range can be greatly expanded with only a few command line statements using PuTTY. Another example, is that it is possible to reconfigure the Pluto to receive and transmit on 2 channels in Full Duplex (2Rx/2Tx). There are other features that make these look like nothing.

Thanks for the videos, they are very enjoyable to watch.

Lovely overview ! Don't forget that the Aaronia SDR receivers with amazing performance are now becoming affordable 🙂

I have the 9€ one
great buy

Hi, I owe a tinysa. Can hackrf one replace tinysaulta ? I was thinking of buying tinsaultra but then i thought why not to buy hackrf one.

Great explanation - thanks!

Usually F2 is greater than F1, because it allows to decrease the range of heterodyne changeover

Such a wonderful explanation of content….🥳🥳

Wow, I'm glad I have experience with audio engineering because it's actually helping me understand this stuff!! It's all just signal processing in the end! Chucking what you don't want, keeping what you do.

xQVm-YTKR9s&t=1m30s 1:30 what causes those funky distortions in the audio?
