David D Levine's "Wavefronts of History and Memory" (short story)

There is an idea here that I've not seen before in this form: radioarcheology. Humanity's radio emissions leaking into space form an useful archeological resource in the hands of someone with the right technology.
PS: I'm not clear how telegraph transmissions leaked in this way, however. I thought they were mostly sent over physical wires.

Apart from this idea, however, it's a very ordinary read.

Story summary.

Thousands of years in future, earth is no longer habitable & only archeology possible is via remote controlled robots. But a radioarcheologist has discovered the WWII era Japan in vivid detail from the leaked emissions of that long gone era...
