Some numerical and analytical results which illustrate how changes in the coupling strength affect the dynamics of coupled current-biased Josephson junctions are presented. It is shown that in certain cases there is a unique interval of the coupling strength in which the basic running solution is unstable, and the numerical results suggest that there are period-doubling cascades and infinitely many multiple-pulse homoclinic solutions that exist in this interval.
