  If the dark matter of our galaxy is composed of nuggets of quarks or
antiquarks in a colour superconducting phase there will be a small but non-zero
flux of these objects through the Earth's atmosphere. A nugget of quark matter
will deposit only a small fraction of its kinetic energy in the atmosphere and
is unlikely to be detectable. If however the impacting object is composed of
antiquarks the energy deposited can be quite large and contain a significant
charged particle content. These relativistic secondary particles will
subsequently be deflected by the earth's magnetic field resulting in the
emission of synchrotron radiation. This work will argue that this radiation
should be detectable at radio frequencies and that present and proposed
experiments are capable of detecting such a signal.
