"His plan involved setting up a transmitter not far from the lecture (supposedly in the theater that his father, a famous stage magician, owned) that would overwhelm the signals from Cornwall. His transmitter, he claimed, was not run at full power: while it was capable of outputting 8 or 9 Amps, he turned it down to 2.5 Amps. He didn’t simply block the signal, but instead transmitted his own morse signal for a short time, claiming that he “studiously refrained from all unnecessary interference”.
His plan worked. Towards the end of the lecture, Maskelyne’s signals were picked up by the receiver, decoded and noted by Fleming, who wrote to the Times complaining of “Scientific Hooliganism”."
