The elemetry values Error and SNR can be used as channel input to provide signal quality information back to the Rx, and to the Flight controller/On-screen display without additional hardware.

The set-up can be done in the Key ⭢ Aux Channels menu. Selecting Err will use error rate. Channel value is calculated as:

Error = 0 ⭢ Channel value 2000

Error = 100 ⭢ Channel value 1000

In case of SNR a logarithmic scale is being used: the highest SNR seen since power-on is being used as reference signal.
