I have a file with a number of 0's and 1's.
And I want to send it via AM modulation
But I couldn't find any SIMPLE AM modulation block
Do I have to write a new AM mod block?

That's really cool. I could use something like that for a machine
with a USRP2 that I sometimes control remotely. How did you get the
FFT to display in ASCII text via an SSH terminal? Was it a
modification of "usrp2_fft.py"? Or is it something you wrote custom
for yourself?

I just started using the USRP2 with GNURadio. I have made a script that
uses the gnuradio library, but it does not try and interface with the USRP2.
How do you do this? Or alternatively is there a list of gnuradio functions
that I can look at that has how to set this up? I have tried doing a go

Hi,
I want to create a block that requires 1 input items and produces
1 output items on a single stream. However, I'm getting the
following message: sched: is requesting more
input data
than we can provide.

That is pretty much everything you need to do. I'm using a 60
MHz clock and calling set_fpga_master_clock() modifies the main master
clock variable, which is used in the tuning of the DDC and also most
(if not all) of the daughterboard drivers query this as well. I've
tested this using BasicRX, LFR
I also have a similar problem.
It seams there is no firmware that can support WBX,and UDP, yet.
If someone knows more about this please let us know.
Also any other solutions to our predicament would also suffice.
Thank you.

Hi,
USRP external clocking documents are outdated so I could not find answer to
my questions.
I modified the USRP board for external clock input, but which parameters
should I change in the code for a different clock frequency (10MHz).
I guess in python I can set it by writing
