How far away can radio broadcasts travel before becoming unreadable?

For example, Winston Churchill's "Fight them on the beaches." broadcast. How many lightyears, if any, could that particular radio broadcast travel before it becomes too distorted/weak to be able to be read?

Radio waves become weaker the further they travel, there is no hard stop limit. It just depends on how strong the signal is and how sensitive the receiver is. If a massive alien civilization can point and coordinate entire galaxy’s array of detectors there’s is no reason they can’t hear us from other galaxies.

It’s like asking where does earth’s gravity stop, it never stops.
