Beamswitch experiments located at Teide Observatory, Tenerife operate at 10, 15, 33 GHz. An area of ˜1 steradian has been covered at angular scales from 5 to 20 degrees ( l=10-30 ) . Sensitivity is ˜10 μ K per beam area at 15 and 33 GHz and 26 μ K at 10 GHz which gives a measure of the CMB fluctuation amplitude to 10 %. These data have been used to provide a separation of the CMB and foregrounds. The radio foregrounds above ˜10 GHz are contributed mainly by free-free emission and by synchrotron below 10 GHz. A sensitive estimate is made of the spinning dust contribution. These data are combined with other CMB data and gravitational lens data to derive estimates of Ω0 and Λ0.
