ADS-B signal

[w6sz]

Hello All,

Have been watching around 1090 MHz with an antenna and noticed this:

Estimated bandwidth about 40 -50 kHz

Does this looks like ADS-B?

The signals are there most of the time. Living under the flight pass of LAX ( Los Angeles )

Rx is RTL_SDR dongle plus 20 dB in line per-amp, antenna collinear outside at ground level..

Is this AM or FM?

Had expected much stronger signals.

Have never seen a ADS-B signal here??

Not sure if that is ADS-B, it could be if it looks like lots of short pulses. Why don't you try ADSB# or RTL1090 and see if it picks up ADS-B packets?
