Writing a simple Tx Program in GRC that transmits a cosine signal

Hello all, I have been able to write a fm receiver in GRC using the 2.4g
daughterboard but as of now i can only test getting noise using the fft
graphical sink. Does anyone know how to make a simple Tx in GRC and the
corresponding blocks that go with it?

Theres not a lot of fm being transmitted in the 2.4ghz range…

For a cosine signal, connect a signal source to a usrp sink. The
amplitude should be around 10k.

I’m new to Gnuradio prorgramming and im exploring the various options
that v have out here…

I tried connecting a sine source to a scope sink …I get the gui however
it is not plotting the waveform … and it gets hung after few seconds.
Can sum1 throw light on this… Also can some1 explain why is sampling
rate specified for the blocks here… coz we will not need sampling to
simply display an analog signal on the scope…

Thanks & Regards,

Hello people …

The problem of the system getting hung is resolved…
However is there anybody who can explain the logic of sampling rate
mentioned in those blocks in grc?

Thanks & Regards,
