Re: [Discuss-gnuradio] LFRX as IF stage questions

The LFRX has 2 inputs. For your application you only need to use one of them, since you have a real IF and not complex IQ baseband. The signal will then be downconverted from 10 MHz by the DDCs, and you will have a complex baseband signal. The LFRX has a clock output pin. You will need to expli
