Dear Sir,
I am using USRP to receive signal, and then plot the signal using "WX GUI

I hope to get the vertical axis as "Power Spectral Density in dBm/Hz".
Is there any way to do that?

PC#1 connecting to USRP#1, will send text message to PC#2 via USRP#2.
The question is, how to get the user keystrokes from the flowgraph at PC#1 ?
I am building the flowgraphs using GRC (Companion).
I guess I need to use
Dear sir,
Why below custom block doesn't work..?
int
console1_impl::work(
int noutput_items,
gr_vector_const_void_star &input_items,
gr_vector_void_star &output_items)
{
int *out = (int *) output_items[0];
int x;
std::
Thank you very much.

Dear Sir,
As an amateur I use GRC to create flow-graphs, but I see many other users
create their flow-graphs in python by hand.
In what kind of cases the flow graphs must be coded by hand ?

When I looked into the attached graphical flowgraph in the first email, the
signal was multiplied by zero (constant multiplier) before feeding into
file sink and audio sink. In this case what you get was probably amplified
noise.
Was it zero or something else?

You should attached the files where you put the std::cout.
The std::cout should be in the work() function.

It seems like the work() function is not called at all by the scheduler.
Probably the ofdm sync block doesn't pr
Part of this question has been partially discussed, as below.
