My radio is 8.33 kHz compliant, but I can’t tune any 8.33 kHz channels?
Some radio types need to be configured for 8.33 kHz channel operations, for example: – By using a mechanical toggle switch; or – By reprogramming via a touch screen display. When operating in a 25 kHz mode, such radios will not tune 8.33 kHz channels. In a busy cockpit environment, it may be difficult to reconfigure such radios whilst in-flight. Hence, during pre-flight checks, make sure that the radio is configured for 8.33 kHz operations. For example, can the radio display an 8.33 kHz channel, such as 132,055?
