We describe the equipment, observational method and reduction procedure of an absolutely calibrated radio continuum survey of the South Celestial Hemisphere at a frequency of 1420 MHz. These observations cover the area $\rm0^h \leq RA \leq 24^h$ for declinations less than $-10\degr$. The sensitivity is about 50 mK $T_{\rm B}$ (full beam brightness) and the angular resolution (HPBW) is $35\farcm4$, which matches the existing northern sky survey at the same frequency.
