Which of the following describes problems caused by poor dynamic range in a receiver?

  1. Spurious signals caused by cross-modulation and desensitization from strong adjacent signals
  2. Oscillator instability requiring frequent retuning and loss of ability to recover the opposite sideband
  3. Cross-modulation of the desired signal and insufficient audio power to operate the speaker
  4. Oscillator instability and severe audio distortion of all but the strongest received signals
