I changed to RX2 and still not activating the receiver on the board.
Try changing the "Wire Format" to complex-int16

I changed antenna’s and I see a signal now in uhd_fft. I just
noticed that when in GRC and I run the flow graph, i don’t see the
RX light come on the board like when running uhd_fft.
I have put the grc file up herehttp://test.utr-software.com/sdr/test.grc
Thanks,

The default antenna port if you don't specify one is always TX/RX --
because you might be wanting to do half-duplex. You can explicitly
specify
the RX2 antenna port in the GRC source block, or just remember that
"unspecified" means, typically, TX/RX.

It just looks like noise.

Hi,
I built all the code today using the build-gnuradio script and
when I create a simple GRC flow graph going from the USRP source
to the waterfall plot, I get no data coming in. I then built gqrx
and ran it and it too doesn’t get any data in from the device to
display on its waterfall. I ran the rx_samples_to_file example
and captured some data, but when looking at it in a hex editor,
it doesn’t look like it captured anything in particular
(http://test.utr-software.com/sdr/rxdump.dat). I ran it with
./rx_samples_to_file —freq=107700000 —rate=1000000
—file=~/rxdump.dat.
I am new to gnu radio and sdr so I’m not yet sure how to dig in
to debug these issues.
Anything help is greatly appreciated.
Thanks,
Greg
How about something really, really simple:
uhd_fft -a type=b200 -f 107.7e6 -s 1.0e6 -g 40 --fft-rate 8
--averaging
