The step missing is after the number 4. Because, after the antenna captures de modultates waves, it has to be demodulated in order to be able to the signal be heard, seen or used.

So, the answer is that waves are demodulated and it before the signal is heard, seen or used.

Before Step 5, radio waves are amplified and demodulated.
