A method, using a frequency-agile receiver in a frequency-agile radio system, for receiving signals from a transmitter transmitting information messages on a plurality of pseudo-random frequencies, comprising the steps of: scanning an available radio spectrum (517, 518); measuring (515) in a portion of the available radio spectrum, at least one of signal strength and quieting and signal lock quality, as a measurement, from an output of said frequency-agile receiver, identifying the portion of the available radio spectrum failing to provide a properly coded reception (508); generating (501) using the measurement and other system cues, a prediction of a level of undesired signal energy, within the portion of the available radio spectrum, present in a future scan of said frequency-agile receiver, and storing (505) the prediction of the level of undesired signal energy in memory location associated with the portion of the available radio spectrum.
