Abstract
A weather band receiver, which may be part of an FM receiver, is disclosed. FSK-encoded data units in an alert packet transmission are detected using a quadrature matched filter circuit. At least one FSK-encoded data unit is captured from the alert packet transmission. Soft quantized bits are extracted from the FSK-encoded data units. The soft quantized bits are saved to memory and used to recover an alert message. Soft quantized bits from two or more FSK-encoded data units may be combined before recovering the alert message.
