RSPduo, HACKrf and RTL SDR comparison

Comparison between three of my SDR receivers, all taken within a few minutes on the same long wire antenna, I love my RSPduo, but for the price, I cant believe how the cheep RTL-SDR dongle works.
I used SDR console for all three, just plugged them in and recordered the same freq, I did not adjust any parameters, though parameters were different between radios, I suspect the limitations between the radios caused the initial settings to be different. enjoy.
