  We cross-correlate the galaxies brighter than mB=18 in the Virgo cluster with
the radio sources in the NVSS survey (1.4 GHz), resulting in 180 radio-optical
identifications. We determine the radio luminosity function of the Virgo
galaxies, separately for the early- and late-types. Late-type galaxies develop
radio sources with a probability proportional to their optical luminosity. In
fact their radio/optical (RB) distribution is gaussian, centered at log
RB=-0.5, i.e. the radio luminosity is 0.3 of the optical one. The probability
of late-type galaxies to develop radio sources is almost independent of their
detailed Hubble type, except for Sa (and S0+S0a) which are a factor of 5 less
frequent than later types at any RB. Giant elliptical galaxies feed "monster"
radio sources with a probability strongly increasing with mass. However the
frequency of fainter radio sources is progressively less sensitive on the
system mass. The faintest giant E galaxies (MB=-17) have a probability of
feeding low power radio sources similar to that of dwarf E galaxies as faint as
MB=-13.
