What? Radio clock is a small radio receiver. How a receiver can interfere with the signal?

  Perhaps this: http://en.wikipedia.org/wiki/Superheterodyne_receiver#Local_oscillator_radiation http://en.wikipedia.org/wiki/Superheterodyne_receiver#Local_... ?

    Interesting! Unfortunately I'm not into radio or electronics beyond resoldering bad caps - so I can't really understand the principle of this. Maybe you could enlighten me, can we surround this oscillator with tinfoil/Faraday cage or something so it wouldn't radiate interference?

      Emission is frequently conducted through the components backward to the input antenna and transmitted. In this case a Faraday cage would not help. Conducted/radiated local oscillator radiation can be substantially suppressed if this is a design criterion.
