Don't know if this is related to my Sample Rate issue, but with a signal well above the noise, I was not able to get a lock or normal-looking constellation:

I just tested with the the R2, I can confirm this is a bug... Working on it.
Also, the default is actually 1M for SDRs like RTL-SDR etc.
from satdump.
Fixed in 5be5ae7!
This was a bug in the resampler, the math resulted in a number of taps that wasn't an integer and got truncated to be, resulting in a crash when actually setting said taps up on startup.
Thanks a lot for finding this one!

Many thanks!!!

Saw the tweet that you had re-released v0.0.38 to correct this - thank you! Is the download the same link in RELEASES?
After re-downloading & rebuilding in a clean directory, I still get the same error when trying to use the 2.5M sample rate:

Ah, I see. I forgot to change the tag to be on the right commit. The binaries are newer and in-line with what's on main as of writing this.
from satdump.
Many thanks!
Sorry.... so should we download from https://github.com/altillimity/SatDump/releases or from some other URL?
from satdump.
I just fixed this. 0.0.38 now points to the correct commit.
To download from main you can either use git clone https://github.com/altillimity/SatDump
or the "Download as Zip" under the code button on the main page.
from satdump.
Excellent - thanks!!
