[Discuss-gnuradio] query regarding wav file recording through wav file sink block
Hello, And when I use multiply constant block in order to increase the amplitude of the wav file, It slightly change the amplitude and change the shape of the signal. PLease someone guide.

I think, because of that when I use the recorded wav file as source for transmission, I didnot get the sucessful reception.

I have successfully record one modulated signal transmitted from USRP into .txt file and done demodulation offline, i.e of that stored data and receive audio from that. But, I have all this done with wav file which is 48k sampled. but my requiremnet is to do AM modulation of 600Hz audio file. for that, I have done the following. signal source(600Hz,8K)- wav file sink AM transmission of this wav file from USRP. record AM modulated transmitted signal in .txt file. and demodulate it in order to receive 600Hz, 8k wav file. during demodulation, I saw signal in scope sink and figure out frequency of that signal through FFT sink, biut when I record received 600Hz signal as wav file through wav file sink, then, that wav file's scope is blank, I get blank wva file, when am I doing wrong. I think, at transmitter side, amplitude of my original wav file source's amplitude is too low. PLease guide.

Re: [Discuss-gnuradio] Kernel for Osmonsdr ?
2019-06-03 Thank you to all for your very helpful suggestions which are greatly appreciated. I will pursue them regards and thank you Jerry To whom it may concern: You do not need a special kernel to run GNU Radio. Everything resides in the userland of the installation (as far as I know). GNU Radio Live SDR Environment, suggested by others already, is a good option. Also, can install a recent vintage of Ubuntu on a USB stick (a full, persistent installation, not as a Live CD mode) and install gnuradio-dev, hackrf, and gr-osmosdr packages to it. Finally, There's a Fedora-based alternative from Marcus Müller (https://github.com/marcusmueller/fedora-live-GR/ ). If you are a Windows user and want to stick with Windows, you can install GNU Radio by downloading it from http://www.gcndevelopment.com/gnuradio/downloads.htm . You will have to use Zadig to install a driver for your HackRF one (just search 'zadig hackrf' on your favourite search engine). Linux will give you better experiences in long-term, though (in terms of speed and flexibility in development). Regards, Kyeong Su Shin ?? ??: Cinaed Simson ??

And at the time the video was made, it was the quickest way to get GNURadio up and running without having to install Linux. It's been replaced by GNURadio SDR environment which uses Ubuntu - a far more friendly and well supported Linux without a steep learning curve. > > On Fri, May 31, 2019, at 11:19 AM, geraldfenkell wrote: >> >> 2019-05-31 >> >> I am new to GNU radio and am following the Michael Osmond videos on >> software defined radio. >> >> In that series of videos he suggests downloading the Pentoo (kernel) >> and using as a live usb hdd to experiement with GNU radio and Hackone >> RF (his hardware device (which I do have)) >> >> I am having trouble with getting my (tried on two) computer to boot >> with the downloaded .iso burned to usbhdd with unetbootin and since I >> realize this is not a problem >> to discuss here, I was hoping that there would be another >> downloadable kernel containing both GNU radio (and companion along >> with the I believe it is called OOT (out of tree) material contributed >> by Michael Osmond. >> >> Does anyone know of another kernel available for download with the >> necessary material preinstalled.? >> >> Any suggestions would be appreciated. >> >> regards >> >> Jerry >> >> >> ___ >> Discuss-gnuradio mailing list >> Discuss-gnuradio@gnu.org >> https://lists.gnu.org/mailman/listinfo/discuss-gnuradio >> > > > ___ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] QT Version of Scope Sink
I've seen multiple messages about the absence of a full-featured QT scope sink, and the lack of a good tool is hampering me as well. A scope is critical to a lot of things - it's a needed tool and the current QT Scope Sink is not what it needs to be. Is someone working on, at least, the porting of the deprecated WX Scope Sink, or perhaps a full-featured scope tool as a sink? Can I help? What is needed?
