We describe the development of the tools and methods of 4.7-GHz band observations on RATAN-600 radio telescope and present a new design solution—a radiometric unit, and the development of an uncooled tuned receiver based on this unit and meant for

During thirteen-year monitoring of the source J0010+1058, four bursts have been observed with an amplitude greater than 1 Jy on a frequency of 21.7 GHz. Using autocorrelation functions, we determined the average characteristic burst time τacf ≈ 1.

We report the experimental results of a study of the sources of 1/fα type noise (hereafter referred to as 1/f-type noise for the sake of brevity) in a total power radiometer. We find this noise to have two main sources in the radiometer: microwave a
