ah, ok I see what you want and that cannot be solved without recompiling gqrx with updated components like osmocom.

Another route might be to make something like boreip or something compatible like rtl_tcp and connect to localhost (127.0.0.1) I have not looked into that deeply enough to help you on that. you might be able to create something in GRC with your source block and a TCP server block, setting the frequency in a compatible fashion. the resulting .py need to be running before you start gqrx.

Maybe my english isn't as good as I hope....
What you said is correct but my problem is different...
Let's think (for example) at gqrx...
It uses osmocom block, gqrx it's not a grc project but in it's interface it asks for a "magic" string that is the parameters used by osmocom block to initialize the source hardware.
Implementing the new receiver in the osmocom block (that already support a lot of hw) will make this receiver ready to be used in a lot of apps.
I hope to have explained... (I really hope!).

Thanks for your time spent to read my post.

just take the examples and replace the osmocom source block with the one provided.
you might need to alter the samplerate down the line as it seems your new source block has a standard samplerate. a simple way is to use a standard additional block to convert i.e. replace the osmocom source block by yours and dome interpolating or decimating block.

HI there,
There's a fantastic receiver out there, it's the Elad fdm-s2.
The company that build this receiver has released a grc source to use the receiver with grc and it works perfectly, it requires only a parameter... the frequency and it output an iq stream.
My question is.... Is there any plan to implement this source in the osmocom block?
I'm a total noob in Linux programming and would like use (for example) programs like gqrx and others that relay on the osmocom block.

The sourcecode of the sink block is available here:

http://sdr.eladit.com/FDM-S2%20Sampler/Linux/Beta/index.php?lang=EN

I repeat... I'm a total newbie here and I don't expect that someone will do the job for me... I just wanna know if someone will implement this receiver and / or is interested in doing it.

Many thanks for any help.

Ps: sorry for my english too 😀
