I wish they would’ve actually discussed _how_ the hack was accomplished

  Uhm, broadcast on the same frequency? It's not that hard to figure out what frequency Marconi was broadcasting on.

    Those were the early days of radio, as in "Let there be light" kind of early. Very few people could even build a receiver, much less tune it.

    Nah. He just did a broad spectrum broadcast which any receiver in the area would pick up. Today, it'd probably be illegal. Tom Scott made a video about it, and mentioned that. https://www.youtube.com/watch?v=sP2qqMegNKA https://www.youtube.com/watch?v=sP2qqMegNKA

  I think what's left unsaid and implied is that the original system wasn't secure in any way, the "tuning" was just choosing a frequency. It's only a "hack" because of the claims that were made. In a way, that would be like advertising a secure horseback large sign delivery service, where the "security" is that the sender and receiver choose one of a few routes between locations, even though the large sign is easily seen and entirely uncovered, making the courier easily identified and the sign when in transit easily read from a distance. The "hack" for that type of system is ultimately so trivial as to be mostly uninteresting.

  It's just a simple AM broadcast. It was only novel at the time because radio was new.
