A modulator, and an associated method, are described for use by a sending station, operable in a communication system, to communicate data to a receiving station upon a communication channel susceptible to fading. The disk drive further comprises a recent write streams list comprising one or more entries, each entry representing an LBA stream. A vertical track for guiding an edge of the flexible curtain is defined between the first and second guide members. In another embodiment, the TV tuner is implemented on a first semiconductor substrate and the digital receiver portion and the power amplifier are configured on a second semiconductor substrate.
