ATSC won't work with SDRPlay

Hi all. I’ve been trying to get the ATSC pipeline to work with 8MHz RF
spectrum recordings from the SDRPlay.
When I provide a 16-bit RAW IQ recording from HDSDR, centered on the TV
channel, the script runs at 100% CPU for a long time and closes but the
output TS file stays at 0 bytes.
Any advice?

In case there are any other folks trying the ATSC receiver. I did some
testing here, and any DC offset spike in the receiver will kill the ATSC
demodulator. I’m not sure a DC block will work, but manually
compensating the DC offset on a bladeRF did work.

I guess offset tuning would also work, but it’s a 6 MHz wide signal, so
you need a pretty large offset.
