Re: Errors when using API example 'play_sdr.c'

You need to provide the library path to the linker. On command line: clang play_sdr.c -lmirsdrapi-rsp On Xcode: Under "Build Settings": 1- Add the "/usr/local/lib" to "Library Search Paths" 2- Add "-lmirsdrapi-rsp" to "Other Linker Flags" If you've i...

Re: Feedback for version 0.9a here

By the way, I have to thank you for your original post in https://www.sdrplay.com/community/viewtopic.php?f=9&t=636 where you posted some sample code in C#. That got me started on writing a bit of code to control the RSP using C# - The analyser is the end product. Well, I am happy and honored t...

Re: Feedback for version 0.9a here

Another very small issue: I think the "Center Freq" field should not accept values "0" and "2000000000" (2GHZ) because then the start/end frequency would fall outside the frequency range of the device. (for example entering 2GHZ and having a sweep width of 10MHZ would s...

Re: Feedback for version 0.9a here

First of all, thank you very much.
I found a very very small issue: the button called "Hide Controls" at the top should change its label to "Show Controls" when you click on it.
This is ok with other buttons designed as show/hide toggle, but not this one.

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.

I've attached some screenshots (with captions): https://imgur.com/a/kfp6S

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...
