Orbital period variations of two chromospherically active binary systems, RT CrB and PW Her, are presented. It is shown that the orbital period of RT CrB undergoes a cyclic oscillation with a period of 53.9years. For PW Her, an alternate change, with a period of 42.7years, is found to superimpose on...
