It is considered markov radio exchange model in a simplex radio network with any quantity of correspondents in which simultaneously only one correspondent can transfer the message, and the message is followed by a pause. Analytical expressions for probabilities of transition from a condition in a condition and probabilities of conditions the radio networks confirmed with results of statistical modelling are received. It is shown, that results of modelling well enough coincide with the received exact analytical expressions. At increase in quantity of tests coincidence degree improves. The developed analytical model of a radio exchange can be used at synthesis of algorithms of division of the mixed stream of the supervision arriving from any quantity of correspondents of a simplex radio network.
