As a collaboration between the National Radio Astronomy Observatory of the USA and the Instituto de Astronomi´a of the National University of Mexico with the financial support of CONACyT, Me´xico, nine receivers for the wavelength of 7 millimeters have been built and installed in the Very Large Array (VLA). These receivers extend up the frequency coverage and angular resolution of the VLA by a factor of two. Observations of a variety of astronomical sources, including H II regions, evolved stars, dust emission from young stellar objects, and quasars have been successfully achieved.
