RTL-SDR buffering and frequency change
I want to use a rtl-sdr as a simple frequency scanner, by setting a RX frequency, reading a block of IQ stream, then switching to the next frequency and so on. How do I sync the frequency set to the incoming buffer? i.e. how do I know what frequency span the read buffer corresponds to, considering t...

At present I am achieving this by multiplying the IQ data from th...
