I tried with both compiled and with downloaded binaries and got the same result:

The USB SDR is recognized as a RTL2832U by cubic, but cubic also barfs right around 1090, however sigdigger seems to have no trouble at that frequency:

Any hints?

No, I don't have any idea.. it's a different tuner however than mine.

That code is mostly just calling to https://github.com/pothosware/SoapySDR, you could try and see if anyone knows about an issue.

Thanks, it's the hardware, I shoulda run rtl_test -t first. I'm not sure why, now sigdigger wasn't having a problem, but hitting a band gap seems to cause a barf.

This is a known (TIL) limitation of this particular variant of the RTL-2832U: https://osmocom.org/projects/rtl-sdr/wiki/Rtl-sdr

I'ma close this as resolved as it is not a software issue.
