  The next generation low-frequency radio telescopes may probe cosmological
models by means of observations of the cosmic microwave background (CMB). I
discuss the prospects for observations of CMB imprints - recombination lines
from the epoch of recombination, \mu distortions and angular temperature
anisotropies - at low frequencies. A future low-frequency radio telescope, like
the proposed SKA, may be capable of attempting some difficult CMB measurements
because of the large collecting area and large element numbers; however, this
will require a telescope design that will allow specialized calibration
strategies and will give emphasis to the control of spurious responses.
