Abstract
This paper reports on the refurbishment of a dual-band 23/31 GHz tipping radiometer previously used to measure atmospheric water vapor content at the Hartebeesthoek Radio Astronomy Observatory. We describe the motivation for the refurbishment, provide technical details of the modifications made to the instrument, and present preliminary test results of field measurements at the site of the High Energy Stereoscopic System Observatory in Namibia. Together with other radiometric measurements, this instrument will contribute to the site characterization of potential radio astronomical observatories in southern Africa.
