[Hackrf-dev] 1090 MHz

[Andrew Rich]

Question. I have a flightaware blue rtl dongle for adsb. It picks up aircraft some 100 kms away ok. But when I run it with a software defined radio I don't see great amplitudes . Why is that ? I would have expected to see quite large signal peaks on the sdr program . Is it because the signal is spread out over 2 MHz that I can see a distinct signal strength ? Does the signal need to be compressed down to a narrower bandwidth ?
