  Obtaining simultaneous radio and X-ray data during the outburst decay of soft
X-ray transients is a potentially important tool to study the disc - jet
connection. Here we report results of the analysis of (nearly) simultaneous
radio (VLA or WSRT) and Chandra X-ray observations of XTE J1908+094 during the
last part of the decay of the source after an outburst. The limit on the index
of a radio - X-ray correlation we find is consistent with the value of 0.7
which was found for other black hole candidates in the low/hard state.
Interestingly, the limit we find seems more consistent with a value of 1.4
which was recently shown to be typical for radiatively efficient accretion flow
models. We further show that when the correlation-index is the same for two
sources one can use the differences in normalisation in the radio - X-ray flux
correlation to estimate the distance towards the sources if the distance of one
of them is accurately known (assuming black hole spin and mass and jet Lorentz
factor differences are unimportant or minimal). Finally, we observed a strong
increase in the rate of decay of the X-ray flux. Between March 23, 2003 and
April 19, 2003 the X-ray flux decayed with a factor ~5 whereas between April
19, 2003 and May 13, 2003, the X-ray flux decreased by a factor ~750. The
source (0.5-10 keV) luminosity at the last Chandra observation was L~3x10^32
(d/8.5 kpc)^2 erg s^-1.
