This paper presents the results of an experimental study of the electronic loading of high-Q superconducting resonators (SCR) for the 10-centimeter microwave band. The effect of technological factors on the field emission current and the parameters of the emitters is investigated. It is shown that for comparable microwave field levels the intensity of the electronic loading of the resonators, fabricated using the 'cold' technology, is considerably lower than in SCR fabricated using high-temperature annealing. The existence regions of resonant high-frequency discharge (RHFD) and their dynamics in the course of an increase in the voltage across the resonator are investigated. It is shown that the components of air and cryogenic residues, adsorbed by the superconductor surface, play an important role in the appearance of RHFD in SCR.
