Abstract We have obtained limits to the rms fluctuations in the cosmic background radiation from two independent VLA observations at 4.9 GHz between angular scales of 12" and 60". With 95% confidence, these limits are: {DELTA}T/T < 0.6 X 10^-4^ at 60", <0.8 X 10^-4^ at 30", <1.2 X 10^-4^ at 18", and < 8.5 X 10^-4^ at 12". We also determined the density of discrete sources between 4 and 30 μJy. The results from the two experiments are in excellent agreement, and the errors are consistent with those due to receiver noise.
