  We report the discovery of a radio halo in the massive merging cluster
MACSJ2243.3-0935, as well as a new radio relic candidate, using the Giant
Meterwave Radio Telescope and the KAT-7 telescope. The radio halo is coincident
with the cluster X-ray emission and has a largest linear scale of approximately
0.9 Mpc. We measure a flux density of $10.0\pm 2.0$ mJy at 610 MHz for the
radio halo. We discuss equipartition estimates of the cluster magnetic field
and constrain the value to be of the order of 1 $\mu$G. The relic candidate is
detected at the cluster virial radius where a filament meets the cluster. The
relic candidate has a flux density of $5.2\pm 0.8$ mJy at 610 MHz. We discuss
possible origins of the relic candidate emission and conclude that the
candidate is consistent with an infall relic.
