dump1090 doesn't decodde

[jh4xsy]

I run caribou_dump1090 (drivers commits at Oct 2, 2023), but NO decode. By using the same ANT, I can decode ADS-B by using dump1090-fa, RTLSDR.

Okay thank you.

I meant – the RF setup – the filter that is used and whether there is an LNA connected.

Sorry for the late replies – we have a war situation in Israel right now…

OK David.

My RF equipment is ６ element Yagi ANT for 70cm band. NO LNA and SAW filter.

As I wrote before, this equipment can decode ADS-B with dump1090-fa and RTLSDR. And I reconfirmed that the ANT cable is connected to HiF ANT port of CaribouLite.

[ImDroided]

I think the I/Q is swapped and dump1090 has no option to reverse it.

[jh4xsy]

I updated to the version committed on February 4, 2024, but it still doesn't work.

[ImDroided]

Where did you see a updated version?
