In order to receive rapid (within a few seconds) evaluation of parameters of ionospheric radio channel near the MUF it is proposed to use new algorithm (method) of multi-frequency diagnostics of radio waves distribution channel. Such diagnostics will allow to evaluate accurately the optimum working frequency (OWF) for ensuring maximum capacity (MC) of radio channel. The new method is based on utilization of priori information about the parameters of the ionosphere along the radio path together with the data of current radiosonde in the radio channel for optimum valuation of the OWF-MC
