RE: [Discuss-gnuradio] TX_RX board installation problem (0x000c)?

If the IF frequency is 43.75Mhz instead of 5.75Mhz, it is impossible that
AD9862 can be faster enough to do Nyquist sampling (64MSPs for 
AD9862). If that is so, how can AD9862 sample the intended signal ?
using bandpass sampling? Matt, can you explain it a little bit more ?

Unfortunately I don't think Microtune ever made one.  The only
difference of consequence is the 43.75 MHz IF frequency instead of 5.75 MHz.
