| | 176 | The strong peak at zero frequency is likely due to some sort of DC offset on the received signal. It is not ideal that it is there, but we can ignore it. |

| | 178 | === Running the Experiment === |
| | 179 | Now, we can finally run our experiment. To do so, simply start the two flowgraphs from GNU Radio using the green play button as before. Start {{{x310_rx.grc}}} on {{{node1-2}}} first, and observe the same figure as Figure 5. Then, start {{{x310_tx.grc}}} on {{{node1-1}}}. If everything worked out correctly, then you should see the following: |

| | 183 | |
| | 184 | Here, you can now see two peaks at 1 MHz offset. Remember that this was the frequency we chose for the cosine wave in {{{x310_tx.grc}}}. |
| | 185 | |
| | 186 | Congratulations! Everything worked. Now we can try some other things, like using a time sink instead of a frequency sink, or transmitting a different waveform. Feel free to give other things a go! |
