  XTE J1908+094 is an X-ray transient black hole candidate in the Galactic
plane that was observed in outburst in 2002 and 2013. Here we present
multi-frequency radio and X-ray data, including radio polarimetry, spanning the
entire period of the 2013 outburst. We find that the X-ray behaviour of XTE
J1908+094 traces the standard black hole hardness-intensity path, evolving from
a hard state, through a soft state, before returning to a hard state and
quiescence. Its radio behaviour is typical of a compact jet that becomes
quenched before discrete ejecta are launched during the late stages of X-ray
softening. The radio and X-ray fluxes, as well as the light curve morphologies,
are consistent with those observed during the 2002 outburst of this source. The
polarisation angle during the rise of the outburst infers a jet orientation in
agreement with resolved observations but also displays a gradual drift, which
we associate with observed changes in the structure of the discrete ejecta. We
also observe an unexpected 90deg rotation of the polarisation angle associated
with a second component.
