<i>Letter to the Editor</i> <br>UHF electromagnetic emission stimulated by HF pumping of the ionosphere
UHF electromagnetic emission (with a frequency near 600 MHz) from the F-region of the ionosphere pumped by an HF powerful radio wave is revealed. Possible mechanisms of the emission excitation, such as plasma mode con-version, scattering or Earth thermal noise emission off the plasma density...
