Dump1090 With RSPDuo Issues

Trying to use dump1090 with RSPDuo. Running the SDRUno software, the device receives ADS-B decodes well.

However running dump1090 with RSPDuo produces no ADS-B decodes. Coomand line used: dump1090 --device sdrplay --interactive --net Software starts correctly,

1. updated databases (first time)
2. detects device
3. correctly interrogates device (eg device serial number reported is correct)

My only unknown is which tuner it is using, so I have attached antenna to both without any successful decodes. Statistics report 100% CRC errors. Why??

Dump file is attached (used --debug G) dump1090.log

Running Win10 64bit with latest updates, SDR API 3.11 Using supplied executable (dump1090.exe) from this page. Have run from std command prompt and from administrator command prompt.

A SDRPlay device has never worked for me either. There's some issue with how samples are processed compared to a RTLSDR-device. 8 vs. 14 bit per. sample perhaps?

OK. Thanks for getting back to me and thanks for your feedback. If I can get a windows build environment set up, I might see if I can investigate. My first thought was there was some extra config needed that wasn't set, but the samples themselves is certainly a possibility.

I might see if I can investigate.

Any progress on this?

No. I've not pursued. I'm using the SDRUno software itself and connecting the feeder software to that.
