[Discuss-gnuradio] BasicRx Daugterboard Frequency Wrapping

  I am hooked up to the BasicRx Daughterboard and wrote a simple applicate
using the GRC to survey the spectrum from 1MHz to 250MHz and run the user
tunable output through the WFM Demodulator.  I can get FM radio stations in
the 88-108MHz region just find.  However, I am also getting copies of these
stations at frequencies higher and lower than this range!!!  It's as if the
frequency I request is out of range and the tuner wraps around.  What's
going on here?  When I tune to 50MHz, I expect to be at 50MHz, not some
other frequency! 

Also, why are there two Rx outputs on this daugther board?  How do they
differ?  Maybe my problem is here.
