Abstract
Observations are reported of a new upshifted stimulated electromagneti c emission (SEE) feature, termed broad upshifted structure (BUS). This wideband emission is found to be upshifted by up to 170 kHz above the pump frequency if the pump frequency lies in a frequency range far fr om a gyroharmonic frequency. The dependence of the BUS feature on the pump frequency and pump power, as well as its temporal evolution, are investigated. The experiments were carried out at the Sura heating fac ility in Russia by modification of the ionospheric F region, using a H F ordinary mode pump wave.
