Jupiter's moons are nowhere near far enough away for this. Radio waves
travel at the speed of light. I'm not sure how far away jupiter is, but
it's a lot less than 1 light year.
Depending on relative positions in orbit, round-trip time never gets
to be more than about 45 minutes. And there would have to be some
equipment running to receive and retransmit, signal loss after
bouncing is severe, even if lasers were used, let alone long waves
like radio.
