I'm wondering whether my flow graph is working correctly.

I think that my flow graph just send a baseband signal

Sender

<http://dl.dropbox.com/u/11382666/02_RXTX/ScopePlotRX.png>Yes, it receives
correctly. But my question is

The sender seems to send just a baseband signal, not a signal whose center
freq. is not 450 MHz

I think that it need to be multiplied by sinusoidal signal...
