1. A digital radio receiver system for receiving signals and having a memory buffer, said system comprising:

  • an antenna for receiving signals from at least a first source;

    a tuner for selecting certain frequency signals;

    a digital demodulator for demodulating the tuned selected signals;

    a memory buffer having memory locations and capable of storing data clusters comprising at least a first cluster comprising a first number of bits of data of a first type received from the first source and a second cluster comprising a different second number of bits of data of a second type received from the first source; and

    a controller for controlling the storing of data clusters in the memory buffer, said controller selecting one of at least first and second clusters of data, wherein the controller selects one of the first and second clusters as a function of strength of a signal from the first source.
