The radio-frequency (RF) signal, observed in a Josephson junction, is shown to stem from bound electrons, tunneling periodically through the insulating film. This holds also for the microwave mediated tunneling. The Josephson effect is found to be conditioned by the same prerequisite worked out previously for persistent currents and thermal equilibrium. The observed negative resistance behaviour turns out to be unrelated to the Josephson effect and originates from the properties of the superconducting current, flowing through the Josephson junction.
