Measurements An comparison between the RTL-SDR and SDRplay

SDRplay 169 MHZ -78Db gain unless stated otherwise

Lna status measuring signal to noise in db LNA lives up to its name and significantly improves SNR

bandwidth measuring signal to noise in db SDRplay seems to be slightly more sensitive on the 200khz bandwith mode -38 Db gain

If mode measuring signal to noise in db Notice how zero if seems to perform slightly better then the low if mode

Why you still should use low if

SNR 169 mhz

Obligatory “RTL-SDR” block diagram Actually r820t block diagram Although impossible with the normal driver the LNA of the R820T can actually be adjusted using a third party driver.

SNR result overview 200khz bandwidth

SNR result overview 1500khz bandwidth
