In direct sampling mode you can "tune" by setting the IF between 0 and 30MHz. > So can the dongle in "direct sampling mode" (with appropriate antenna > connection) receive > 14.4 Mhz (Nyquist) ? Yes, and it has nothing to do with Nyquist because the sample rate you receive is only 2MHz or so as per normal. Direct sampling mode does not capture a wider band than normal, it just uses a different method to tune the receiver. So the oscillator frequency is irrelevant, and Nyquist doesn't come into it any differently with direct sampling than with normal sampling. Cheers, Adam.
