Re: [Discuss-gnuradio] ATSC won't work with SDRPlay

[Ron Economos]

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.

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?
