We installed a new common LO box for the 2 mm and 1.3 mm G2 receivers. The LO for these two receivers is now remotely tuned from the control room and done much quicker. However, sky frequencies below 133 GHz cannot be reached at the moment due to a limitation of the Gunn oscillator. We are working on extending the 2 mm frequency range towards the lower end. The accessible frequency range for the 1.3 mm G2 receiver has not changed.
