Re: Beta release of gr-osmosdr for Gnu Radio and GQRX

Update:
I fetched the latest changes and built it again;
I noticed a new "SDRPlay Source" is added to the source.
With the new "SDRPlay Source" in GRC (instead of "osmocom Source"), it works great now.

Re: Beta release of gr-osmosdr for Gnu Radio and GQRX

I was/am using automatic gain.
I believe it has nothing to do with gain, but with the GRC block.
For your info: I can decode FM broadcast on GRC, which means it is working; I just have problem with the spectrum.

Re: Beta release of gr-osmosdr for Gnu Radio and GQRX

Hey Andy Thanks for the update. I've already written about a list of problems I've encountered before, here: http://www.sdrplay.com/community/viewtopic.php?f=9&t=2798 I can confirm that it works (tested with "GRC", "gqrx" and "osmocom_fft") I compiled and tested thi...

Re: Thread for gr-osmosdr and GNURadio problems/ideas

I will create a list of differences between Soapy's and gr-osmosdr's implementation.
We can use that to improve the situation on gr-osmosdr (hopefully)

Re: Thread for gr-osmosdr and GNURadio problems/ideas

I was playing with gnuradio some time ago and I also used the soapy via gr-osmosdr without problems. I can use Soapy on Gqrx, but not in GNURadio. Regarding the "aUaU...": Do you get no audio at all or a crackling audio with the "aUaU" correlated to the cracks? As far as I remem...

Re: RSP1A: wobbling spurs around 2.335MHz * n

More info about my above post: 1- I'm sure a lot of you already know: changing the IF mode, changes these frequencies; 2- In Zero-IF mode, these are my spurs on RSP2: 2.297MHZ , 2.326MHZ 4.599MHZ, 4.658MHZ 6.906MHZ, 6.993MHZ 9.187MHZ , 9.300 MHZ and on and on. These "pairs" are only visibl...

Re: RSP1A vs RSP2 internal noise

Update: 1- I will follow up the spurs issue on the other thread to prevent duplicates on the forum. 2- As per the internal noise on RSP2, the situation will be much better with manual gain (though I was and am curious why with automatic gain and similar settings, RSP2 and RSP1A show different noise ...

Re: RSP1A: wobbling spurs around 2.335MHz * n

Well in my case RSP1A is better than RSP2. As I've already posted here (http://www.sdrplay.com/community/viewtopic.php?f=7&t=2797) about my internal noise issues, I only have one such spur on RSP1A, but two on RSP2 ! RSP2 without any antenna attached on CubicSDR on a MacBook: (I've the same situ...

Thread for gr-osmosdr and GNURadio problems/ideas

Hi I am creating this topic to discuss various problems that we have on gr-osmosdr and GNURadio (and also gqrx) when it comes to RSP support. We can discuss solutions and then some of us can help in fixing them by proposing our own changes via pull requests, or creating issue/ticket on the respectiv...
