I've attached updates to your graph that should make it behave more rationally:On Oct 3, 2014, at 7:30 PM, Marcus D.

2Msps sample rate -- consistent with your programmed 1.7MHz analog bandwidth Deleted antenna spec in source block--it contained invalid specification Made the device address spec valid Moved things into user-changable variables: freq and gainMade both source and FFT use the "samp_rate" variable, so changing that variable will change both source and FFT sink Made FFT sink turn on averaging, and use "freq" variable to set center frequency
I'd suggest looking it over carefully, and comparing against what you originally had.
