  We present sensitive 3.0 cm JVLA radio continuum observations of six regions
of low-mass star formation that include twelve young brown dwarfs and four
young brown dwarf candidates. We detect a total of 49 compact radio sources in
the fields observed, of which 24 have no reported counterparts and are
considered new detections. Twelve of the radio sources show variability in
timescales of weeks to months, suggesting gyrosynchrotron emission produced in
active magnetospheres. Only one of the target brown dwarfs, FU Tau A, was
detected. However, we detected radio emission associated with two of the brown
dwarf candidates, WL 20S and CHLT 2. The radio flux densities of the sources
associated with these brown dwarf candidates are more than an order of
magnitude larger than expected for a brown dwarf and suggest a revision of
their classification. In contrast, FU Tau A falls on the well-known correlation
between radio luminosity and bolometric luminosity, suggesting that the
emission comes from a thermal jet and that this brown dwarf seems to be forming
as a scaled-down version of low-mass stars.
