Recent theoretical studies of the e+e- → K+K-γ process are described. Three main reaction mechanisms are considered: the initial state radiation, the final state radiation and the strong interaction between the outgoing K+K- mesons. The K+K- effective mass distributions are derived for three different models which in past have been used for a description of the e+e- → π+π-η data. Also the numerical results for the angular photon and kaon distributions are presented. A new model of the e+e- → M1M2γ reactions is outlined which can serve for multichannel analyses of the radiative processes with a production of two pseudoscalar mesons M1 and M2.
