Did you manage to note the HackRF block parameters if you were able to get that to work? I'm running two separate hackrf about 10 meters apart and it fails to demodulate The goal is tx and rx data in real time ( JSON + video streams ) but I can't even get this to work haha "packet_headerparser_b :info: Detected an invalid packet at item 1448. header_payload_demux etc etc"

Is that a Realistic DX440 on the drawer? I grew up with that radio, loved it

Super cool!

I am curious as to why the band pass filter is applied to the -600k to -700k range not only on the positive frequency side but also on the negative frequency side based on the center frequency (here, 0Mhz).

why use soaypySDR library ....E200 does support official USRP b200 UHD library

Great, can these be possible for bladeRF 2.0 xA4 board

what id you are installing to use on codeblocks?

Very nice and informative lecture on GNU radio. I am a beginner on GNU radio. I have a question-- is there any way that we can extract/ export the data of the displayed graph into a .txt/ .csv/ .dat file. Thanks in advance.

I seem to have a new question posted , but I cannot see or respond to it here? It shows in notifications, but it has no reply option.

All of the URLS are missing the colons. Also using a screen recorder (you could use the phone for audio capture and then merge the two) would have made the video must easier to view.

Great video series, thx! By any chance, have you taken a look at the GNSS Firehose RF front end? It sells for about $800, offers three synchronous channels, a great tcxo, ethernet tcp interface, and 70 Msps sampling. Pretty amazing device, tho it is optimized for GNSS work (which is what i do).

Hello Dale, i have grown very fond of your flowgraph but i do not have the exact SDR you own, can i adjust some things like the osmocom source to maybe get it to work on mine?

Hi would the power be the same for 33 ft of the times lmr 240?

I wonder how the rg58x would do at ten feet. Thanks for the video, I am looking at buying the slim jim n9tax for portable use and I made the right decision buying the lmr 240 for long distance cable runs.

I was thinking, like we can connect our coax cable to ethernet cable and directly access the internet similarly can we connect antenna to coax cable and coax to ethernet cable and can access live tv from the PC (without any external converter)

Don't forget that you get the same benefits on receive as will. Just by getting decent coax, you get a cheap linear AND pre-amp

Really surprised to see someone relying on Linux like this but still insisting on using Windows. Is there really no Windows software to run this?

Hello! im a student doing a networking class. This is very informative, thank you so much for showing off your awesome project! I love this kind of thing! I hope you continue to do these things. I'm very passionate about networking and i just love to see other people the same way. Greetings from Georgia (USA) and I wish you well !!

That's cool, didn't realize it was still legal to broadcast TV! I should figure out if any is broadcast in my area.

Very cool project, i do find it very interesting though that you could have all the skills necessary to set up wsl and whatever other software is used to make this work and still not have been exposed to someone saying Ubuntu (to learn the pronunciation), or having the familiarity with the terminal to know why youre having the hit enter twice. Not that that takes away from the video, just a curiosity. What is your background?

btw the reason you have to press enter multiple times is when you click on the window you are actually selecting some blank text (highlighting somewhere on the screen) and when you press enter, it cancels it instead of running the command, so if you click on the top of the window (the title bar) you won't have to press enter multiple times as you won't be selecting anything.

interesting, which is the format of IQ file captured?would be possible to convert in ASCII for e.g. Matlab processing in I,Q I,Q data format?

its pronounced Ubuntu

Can't get over the "yh-boohn-ta"

great project!

Just FYI Ubuntu is pronounced oo-boon-too

Great video ❤❤❤❤❤❤ I would suggest that if you can please show the hardware setup. For great+ video 🎉❤❤❤ Still love this video.

Hello, are you using the FPGA functions to do this? Could someone do the same with a BladeRF 2.0 xA4?

I found a comment, but I can only read part of it and cannot reply to it ?

Hello! When I run the command make -f makefileM1Brew I get the following error: ld: warning: search path '/opt/X11/lib' not found ld: library 'glu' not found clang: error: linker command failed with exit code 1 (use -v to see invocation)

Thanks for the video. I am new in GnuRadio and I have downloaded the file as you showed us and opened it with GnuRadio CR . I can see the Blocks but unfortunately I cant run the Program. Can you plz help me what is the reason?

hi, how you find tv channels frequencies?

can this receiver be used to obtain data from WiFi networks? those using 802.11g/n . I cant really tell exactly how this all works. Is OFDM used in unison with another modulation scheme or something? As I see things like BPSK or QPSK mentioned also but don't really get the practical difference

What kind of balun do you use where the coax connects?

Thanks Dale Ranta, please what version of Raspbian os did you use?

Hi Dale, I am an engineering student and I'm new of GNURadio.I am developing an OFDM distance ranging system, I need to add the TX and RX timestamps, I noticed that RX time could get from stream tags, but I have no idea of adding TX timestamps, I am wondering if you know how to solve this problem?Thank you!

HOW about trying to add a upper and lower hat onto the wall antenna ?? They supposedly really work from what people have told me Dale. Have a Happy New Year fella too. Peace !!!

In 2023, I'm mulling over purchasing an Icom IC-R8600. I already own an RSPdx SDR receiver and am combing thru anything comparing both. I know, after putting in quite a few hours of internet research that, if I were to purchase the Icom, I'd be pretty much out of a lot more money by going the Icom route. However, it seems, everything else being equal, the Icom is a stand alone radio, no pc and all of its nuances are required. Reason why I'm looking to get the Icom is due to PC based SDR's problems. I've come across, many times, instances where I would launch SDRuno and come across many audio problems. Messing around with virtual audio cables, input/output settings, drivers, etc., it's all just a big pain in the ass to figure everything out. I would spent a LOT of time diagnosing Windows audio settings, specially after some Windows update. I hate that. Used to own an Icom IC-7300, great radio but, I needed the money and it being a ham radio able to transmit on bands I was not licensed to, it was an easy decision to sell it (plus, I got more for the radio than I what paid for new). Nowadays, I'm ready to go back to the "old fashioned" way of listening to a radio and, new R8600, imported from Japan, are selling way cheaper than purchasing them locally. In your particular video, I can hear a definite difference, though I'm not really into FRS monitoring, I can really hear a clear difference favoring the Icom.

greetings, dale! I've been using gnu radio on an ubuntu 22.04 virtual machine within a windows desktop to transmit and receive a specific signal from/to a single bladeRF xA9. I am using actual antennas on the TX1 and RX1 ports. The signal samples come from a .bin file that I connect directly to the osmocom sink, and they are already modulated in baseband. However, I cannot seem to recover a near-perfect signal, even though the SNR seems to be very high. I know it is a kinda vague description. However, do you have any idea of what it could be? Pocessing the Rx signal in MATLAB, I saw some spectral differences when compared to the original signal. Apparently, the board filters out some part of it...

thanks for the video Dale. love finding underviewed gems that answer exactly wat i was looking for

We're also seeing/hearing the effects of your antenna radiation pattern as well.

FRS Family Radio Service is around 462 MHz, not 262

Good example of the improvement in signal to noise you get going from 8 bit to 12 bit analog to digital converters. I have a Red Pitaya clone that I have been using listening to HF frequencies. It has a 16 bit front end, very impressive.

Hi Dale, I am an engineering student and I do not have extensive knowledge of Gnu Radio, I am developing a cognitive radio project in OFDM using 3 Blade RF, I need to establish the base communication of the transmitter and receiver, but I get an error with the VLOK lib. This is the error. [WARNING] SoapyVOLKConverters: no VOLK config file found. Run volk_profile for best performance.

you are not following best practices

Hey Daie, have you gotten that Ham license yet, so that you can do some over the air SDR transmit testing?

nice job! I love seeing how far hand held CB's can go... I have heard this Cobra 38 will modulate up to 10 watts.. so it should do really well for range..... but using the HA TA it didn't sound like it could go much more than your two mile test.... thanks for sharing.

Interesting test, thanks. It would be nice if you could talk about the physical properties of the 58A/U vs the 240. Everyone isn't just running 70cm indoors on a desktop :) Is the 240 more or less flexible, in cold vs hot weather, bend radius, weight per linear foot, etc. Thanks again.

Hey, Ive been working with USRP B210 and want to transmit and receive packets in 5Ghz. What changed should I make in order to achieve my goal?
