The electromagnetic background of the high frequency radio range during solar eclipses

We examine variations in the level of the electromagnetic background of the high-frequency radio range based on monitoring data conducted in Tomsk. We establish the main laws by which it changes in various frequency bands during three solar eclipses observed in Tomsk: the level of the electromagnetic background increases to 40 dB at frequencies of 3–7 MHz, decreases to 40 dB at frequencies of 11–30 MHz, and remains almost unchanged relative to the level of control days at frequencies of 7–11 MHz.
