Purpose: The goal of the work is improving the efficiency of interferometric studies of cosmic radio sources at decameter waves. Design/methodology/approach: The URAN interferometer network observations are made usually at frequencies of 20 and 25 MHz with the recorded bandwidth of 250 kHz. The URAN receivers provide an effective software filtering of interferences and reducing the re... https://www.foldlyers.shop/product-category/open-frame-din-rail-type/
