A search has been conducted for unpulsed radio emission from 25 pulsars. Four of these pulsars were found to exhibit a significant unpulsed flux, the ratio of the peak flux to unpulsed flux (beaming ratio) lying between 55 and 2300; for the others lower limits are found for the beaming ratio ranging from 40 to 16000. For the pulsar PSR 1929 + 10 it is also demonstrated that the unpulsed flux comes from a region within about 100,000 km of the neutron star. A possible correlation between the level of unpulsed flux and the orthogonal component of the pulsar magnetic dipole moment implies that the pulsars with detectable unpulsed flux may be those in which the magnetic dipole is nearly aligned with the rotation axis. Two previously undetected pulsed features are also reported: one situated at a longitude of 120 deg relative to the main pulse in the integrated profile of PSR 1929 + 10, and the other at a longitude of 225 deg in the integrated profile of PSR 1818-04.
