I don’t think we have the technology or will have the technology any time soon to send a focused enough powerful enough radio signal over 150 light years. As radio is subject to the inverse square law, the amount of power you’d need is gigantic. Like black hole swallowing a bunch of stars levels of energy. Iirc anything over 25 light years is pretty much a no-go for radio as the detectors get ridiculous and the signal to noise ratio makes it indistinguishable from background levels.
