Found out - it works. Thank you!

No I didn't - maybe I should try that! The reasons I didn't were 1. I don't know how to, 2. I was afraid that the two copies of rtl-sdr would use the same kernel module, so if I blacklisted it, the other copy wouldn't work either.

I've installed rtl-sdr on a raspberry pi. Now, since I'm going to use it remotely, I want to use Stephen Blinick's ring buffer rewrite of rtl_tcp as detailed here: https://www.rtl-sdr.com/significantly-improving-rtl_tcps-performance-with-ring-buffers/ Unfortunately, I started out by installing rtl-s...

I believe I've attached a screenshot of SDR#. There's no signal right now, but when there is, it's still unreadable.
