Abstract: This report discusses propagation and performance measurements that were opbtained over a digital troposcatter communication link between Bocksber, West Germany and West Berlin. The measurements were unusual because three gerneral types of data were collected simultanewously over the link: propagation data, digital performance data and meteoroligical data. The propagation data include received signal level (RSL) and multipath measurements made with a channel probe; the performance data consist of a bit-error data obtained from 1.544 Mbps T1 bank; and the meteoroligical data (in the form of radiosonce messages) have been used to generate profiles of the radio refractive index over the link.
