With infinite energy and infinite funds I suppose they could. But it takes a tremendous amount of energy and money to send out even a second's worth of signal being able to reach other solar systems.
Alex probably knows better than me, since I only read about the problem being brought up by astro physicists. There's a reason why we sent out Voyager 1 with a disk on board instead of continuously broadcasting signals.
