The pira silence detector works well to detect silence but it cannot normally distinguish between regular audio levels and a wide band noise produced when the transmitter is off.
The solution for this is to run 2 detectors
One for silence one for noise detection.
The trick is that the noise detector is always in alarm
when it is satified the email it sends out is that we are off the air
