Preliminary results of measurement of the cross section for the process e+e− → K+K− in the range of c.m. energies between 1.075 and 1.975 GeV are presented. An analysis was performed on the basis of an integrated luminosity of 62.9 pb-1 accumulated by employing the CMD-3 detector within the experimental runs of 2019. The suppression of the background from the processes e+e− → e+e−(γ), and π+π−(γ) and the background of cosmic-ray muons was accomplished with the aid of information about specific energy losses of charged particles in the layers of the liquid xenon calorimeter of the CMD-3 detector. The preliminary results of the present measurement of the e+e− → K+K− cross section are in reasonable agreement with the results of earlier measurements and have a commensurate statistical precision.
