We used a 1 m diameter flux collector and an ^3^He-cooled bolometric detector sensitive to radiation with wavelength between 1.86 and 2.34 mm. Observations were carried out during the Antarctic summer and are limited by atmospheric emission fluctuations. We found an upper limit for CBR anisotropies {DELTA}T/T(2.75 K) < 2.5 x 10^-4^ at 95% confidence level at 1.3^deg^ of angular scale. Galactic emission was also detected in the region l = 300^deg^ b = -10^deg^.
