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,

Well, for one, your FFT block disagrees rather dramatically with
your UHD source block about the same rate, which you've selected as
10Msps. I'd
go for 6.25Msps, and make certain that your source block and FFT
block agree on sample rate. And if you're really wanting the 1.7MHz
that
you've programmed in the source to 1.7MHz, you don't need more
than about 2Msps sampling rate. Very few daughtercards have
variable
analog bandwidth, the TVRX2, DBSRX2, and perhaps XCVR are the only
ones with variable analog baseband/IF bandwidth.
