a question like this pops up every once in a while. Is your dat file

Is there any way you could provide an example of something that is

Also, have you tried reducing the throttle to something pretty

whether i could see the video or not.
When i transmitted the file using benchmark_tx.py file ,i am getting noise

It may be that you didn't make test script?
And you should do make before make test.

Hello everyone, let me explain my question:
Let the input signal,Fc=cos(2*pi*fc*t+a(t)),fc is the carrier's
frequency,and a(t) is the information which modulated into the carrier.
But the SDR(software define radio)doesn't processes the input signal Fc
directly, it just deal with the I/Q signal.
Hi list,
I have been playing around with the new message passing interface, but was
unable to detect the start of the flowgraph in my asynchronous block.
The block has a worker thread that will request frames over the network
and send them out over a message port. The worker thread is started in

I created some blocks using c++, gr_modtools and used GRC in order to define

problem is that is not working, when I use one of

Thanks very much for your reply. I also searched online about the

the TX/RX antenna. So

Why are you trying to transmit it using the benchmark scripts? Why not
