Results and problems of the model for Josephson pulsars are summarized and discussed. In this model coherent radio emission is generated in the mantle of a neutron star by the Josephson effect. The matter from the mantle may flow along the magnetic field through cracks in the crust, forming a magnetized plasma wave guide. Radio emission propagates in this plasma flow as polarized normal wave-guide modes. A line-of-sight section gives the observed polarized structure of pulses. In some cases polarized X- and γ-ray emission may be generated in this flow in or over cracks. Such an approach allows us to avoid the typical problems and is in agreement with the main observational results.

1 The Josephson pulsar model has problems, of course, and the problem of radio emission escaping is one of these. But the criticism by Andriesse (1980) actually did not touch upon the model, and I consider the critical arguments as either moot or as misunderstanding.
