  We present the first observational limits on the predicted synchrotron
signals from particle Dark Matter annihilation models in dwarf spheroidal
galaxies at radio frequencies below 1 GHz. We use a combination of survey data
from the Murchison Widefield Array (MWA) and the Giant Metre-wave Radio
Telescope (GMRT) to search for diffuse radio emission from 14 dwarf spheroidal
galaxies. For in-situ magnetic fields of 1 $\mu G$ and any plausible value for
the diffusion coefficient, our limits do not constrain any Dark Matter models.
However, for stronger magnetic fields our data might provide constraints
comparable to existing limits from gamma-ray and cosmic ray observations.
Predictions for the sensitivity of the upgraded MWA show that models with Dark
Matter particle mass up to $\sim$ 1.6 TeV (1 TeV) may be constrained for
magnetic field of 2 $\mu G$ (1 $\mu G$). While much deeper limits from the
future low frequency Square Kilometre Array (SKA) will challenge the LHC in
searches for Dark Matter particles, the MWA provides a valuable first step
toward the SKA at low frequencies.
