If you put your flow-graph itself (.grc file) somewhere, or
attach it, we can take a better look.
What kind of comptuer? (OS, CPU/MEM specifics, etc).

Hi Marcus,
Thanks. The .grc file is attached. Other details:
o Intel(R) Core(TM)2 Duo CPU E8400
@ 3.00GHz
o Memory 3GB
o OS 14.1
Ubuntu
Cheers,
Dan
I've attached updates to your graph that should make it behave more
rationally:
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 gain
Made 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.
