Just started using GQrX a few days ago. keep your sdr series rolling...
Brill 2 videos got Linux computers and pi2 got the rtl-sdr in the post can't wait to fiddle about with it all. Keep up with the good work !!
great video, showing easily how GQRX works. helped me with tunning and understanding better the software
Thanks for the video mate - I find it really interesting!
thanks so much for watching!
Hi, Steve - many thanks for the videos, esp showing the steps and explanations in such detail.
So glad it helped!
Hi Steve. Excellent series of SDR related videos! Keep up the great work and look forward to seeing some more similar videos in the near future??? Top marks!

Thanks so much. It's comments like yours that keep me motivated to keep making videos. Thanks again!
Awesome video !!! plenty of raspberry pi SDR stuff on RUclips.. most are silent movies. (no narrator) congrats and thumbs up
Yeah, I get frustrated too when you find that perfectly titled video, and then you can't see or hear what the guy is doing even if he knows his stuff.
Thanks for the nice video
Can the Gqrx software be used without a keyboard, just using a touch screen, do you know?
Did you ever have a chance to look into and figure out if Digital Trunking was a possibility on the Raspberry Pi or have any success with it? I was thinking about picking up an SDR as a hobby and certainly prefer my Linux machines and Raspberry Pi's to using a Windows solution, for sure.
I got gqrx on a pi 3 b+ but get no sound out of the factory sound card. I hooked a Bluetooth speaker up and get sound. I'm using it for a second feed for my scanner that I broadcast.
Does anyone know how to get the sound working on AM mode other modes i have sound 🤔
Thank you very much ... you are a great man .. thank you for the detailed explanation, I managed all and I suggest if you can make it easier for others by writing the commands here so anyone can copy it and paste .. I managed to makes it in the second time .. for beginners like me I didnt know that I have to create a folder (etc and apt) so I stuck at the first time .. but WELL DONE man .. Keep going .. Good Luck (Y)
Sorry about that. it was all on Kenn's blog which I linked to from the first video. Here is the link again for anyone else who sees this comment ranous.wordpress.com/
My Raspberry Pi 7" Touchscreen does not concentrate the gqrx screen where I can see all the edges of the program and the options with out dragging everything everywhere. I have tried changing the screen resolution with no luck. Anyone else run into this with the 7" touch screen? I also have a Bluetooth speaker attached and get no audio out from this, have tried all the settings on this too. My unit is RasPi3
Greetings Steve. Super excellent tutorial. I closely followed it and was able to crank up my receiver with success. Even with new versions being released I was still able to get this bad boy running. I did run into one problem though. I can see on my scope i have reception of FM radio stations, but I am unable to get any audio thru my devices, even the small audio screen at the bottom right isn't showing any activity. Do you have any trouble shooting ideas how to get it up and running?
Hi Steve Im over in cyprus and not got any access to Amatuer radio Hardware, so I have a Raspberry Pi 4 4G and NooElec NESDR SMArt HF Bundle: 100kHz-1.7GHz Software Defined Radio Set for HF/UHF/VHF including RTL-SDR, Assembled Ham It Up Upconverter, can you make a recomendation for SDR Software that will run on RSPi 4 and aslo work well with the Nooelec decoder.
Many Thans

Hi, nice work!.. I have nice quick project in my mind.. But i know nothing about programming.. Im wondering if these can be modified in audio range (20-20k)?
Hey Steve awesome video. I Have an RTLSDR and interested in what you’re using for audio output. I have a PI4. Other than headphones what do you recommend for audio output? Thanks Gary Ke2yk
Thanks for this video, can you make a video to decode a Navtex signal on 518khz with fldigi or someting using the raspberry pi with an rtl-sdr stick?
any updates on digital?
What if RTL SDR doesnt appear on my list?
Such a fun hobby! Thanks for the awesome series. I'm following it closely! It would be rad to figure out how to do digital and even regular analog trunking decoding on the Raspberry Pi.
One question: How are you getting audio output from your Raspberry Pi? Do you plug it into external speakers?
See if this helps: www.raspberrypi.org/documentation/configuration/audio-config.md

Which version of RP do you use? I have only old (first version) of the Raspberry PI computer. I doubt that it will work, maybe too slow for that task? Thank you in advantage.
it was too slow for the task. i only did it as a proof of concept
Thanks for the info.
Great videos! Nice step by step instructions. Everything is working for me except no audio out. (I am just using a monitor with no HDMI audio.) I plugged in a generic usb sound "card" and set that as the default audio out but still nothing. What are you using for the audio out?
Thanks Bill
Audio out goes to speakers.
I want an SDR that can display activity from DC to daylight. I'll wait here until I get it.
Hey Steve... have you looked into more about making a RPI into a mobile police scanner.??? This is a project I’m just starting, and I’m worried about getting the trunking to work on a PI...
brianh0220 I am looking to get it working too, did you ever get it working like Steve did in windows?
This works with RPi 3 and a regular monitor but freezes after two seconds if I use the Raspberry Pi 7" monitor. Anyone using this setup, I would appreciate viewing your setup parameters. Do I need to overclock the processor?
Maurice Craft Would you not be better to use the Pi3 as a headless unit? I use the nooelec smart on my Pi3 and run rtl_tcp, then pick it up with an android tablet on RF Analyzer to do the heavy lifting. Give that a go and let me know if you get stuck.
Will do. Thanks for the information.
I love Dan's headless mode setup, but for more on Pi touch screens, go to rtl-sdr.com and search for 'touch screen' and 'touchscreen' and see articles dealing with those.
Cool, is this op to-date?
Steve thanks for the videos Very informative. I will add one constructive comment. You have said in a couple of videos that the Ham Bands were dead which is never the case if you setup the SDR correctly. You can not use Quadrature sampling for HF bands. You need to change it to I or Q sampling, Q on my SDRs, and then you can use the LSB, USB, CW modes. That should help you get in the HF (or what most people like to say Shortwave) bands. Hope this helped. Look forward to another video. W9KHP
constructive comments always appreciated. thanks for watching!
got the mega and kilo mixed up bud, though thanks for the info on the pi.
hard to be perfect in these vids. thanks for watching!
I've gotten GQRX to work on an Rpi3 but for some reason not an RPi4.
I haven't tried. Anyone else????
@@TahoeSteve if it makes any difference I have the 4gb ram model, using Raspbian.
I have it working on my pi4 4gb Running the latest version of the Raspberry pi OS. Installed GQRX using raspberry pi software installer. In Configure I/O devices Device = Realtek RTL2838UHIDR left everything else on the panel in default setting. just noticed the date of your post. I imagine you've already solved the issue by now.
would help a little to actually be on frequency . Your a hundred cycles off . Might sound a little better actually at 162.475.000..just saying
Amazing little devices, eh? Just think what this would cost say 10, 20 or 30 years ago if it was even available in a larger piece of hardware. Amazing time we live in. What is going to like in another ten years?
so, so true, thanks for watching!
