Abstract
We present the refurbishment of a 23.8/31.5 GHz tipping radiometer (WVR-III) to characterize atmospheric opacity for
astronomical sites. The mid-life upgrade will bring new life to the 20-year-old WVR-III with most control functions now
embedded on a Raspberry PI 3B+ (RPi-3B+). The radiometer will be installed alongside the 225 GHz radiometer at the
Large Millimeter Telescope site in Mexico and in 2021 it will be taken to the Hartebeesthoek Radio Astronomy
Observatory in South Africa. Later, it will be deployed to Mt Gamsberg, Namibia to perform PWV site surveying for
potential future radio astronomy telescopes. This paper describes the new control and data acquisition sub-systems that
are controlled by the RPi-3B+.
