Thank you for your email, and I appreciate the communication. I did have one last question: If I were to make a change to the code and need to recompile it, are the steps the same ones listed on the wiki under "building the software", or is there a different make process?

Hi Robert,

It sounds like you're looking for the `buf_num` argument to rtlsdr_read_async. This is in rtl-sdr.h: https://git.osmocom.org/rtl-sdr/tree/include/rtl-sdr.h#n362 .

I run into problems like that all the time, myself. Due to my issues, I've found it hard to collaborate on this project myself. See mailing list archive of contributions that were minimally addressed. I try to focus around communication that's more reliable than radio now, like memo.cash .

But I'm still passionate about helping rtl-sdr grow.

I'm trying to run utilities that capture 978 https://github.com/mutability/dump978 & 1090Mhz https://github.com/mutability/dump1090 traffic simultaneously, but I can't seem to stop rtl_sdr from allocating too many zero-copy buffers and preventing both programs from running simultaneously (I'd like to cut

Is there some line I might have overlooked, or some additional
