npub1e2z26rv2fk5f9k8ex3xtu6whu5425u7dvn4ju40xr4hfve5q83uqyyldaf (npub1e2z…ldaf) Whoa, Mr. Nyquist just called, and let me know that 3.2 Megasamples per second match in fact a maximum frequency of 1.6 MHz, not 1.6GHz. In fact, he further explained, since you're doing IQ sampling, you end up with twice that, above and below your reference frequency, for a total of 3.2MHz.
But that's the signal *bandwidth*, not the maximum receive frequency. The latter is controlled by the oscillator that is used to generate the reference frequency, and limited by the range of that oscillator and the quality of some other components in your signal path.
