You need to be aware that if you run the SDRPlay receiver at 10 MHz the ADC resolution is only 8 bits.
For info the SDR1A has 14 bit ADC at 6 MHz or smaller sample rate, 12 bit for 8 MHz, and 10 bit for 9 MHz sample rate. The older RSP1 was only a maximum of 12 bits.
In terms of usable bandwidth the SDRPlay at 8MHz is around 6.8 MHz (+/-3.4), at 9 MHz is about 7.8 MHz (+/- 3.9). When the sample rate is increased to 10 MHz the signal becomes a lot noisier and the gain needs to be turned up to bring the noise bck down again. The usable bandwith at 10 MHz is about 8.2 MHz.
