Passband Tuning
Passband tuning manipulates the tuning circuitry of the transceiver, allowing "close together" signals to be separated - one is rejected by the filter, one is allowed to pass through. It is similar to IF shift, where the IF of the transceiver is shifted slightly to tune in slightly off frequency signals.

Passband tuning and IF shift are used because simply narrowin down the passband wold produce muffling of any audio signals.
