Time for something juicy: Remember this? "TRUMP APRIL 26th" mysterious radio transmission

The transmission lasted for several WEEKS.

Some people hear "Trump april 26th" Some people hear "Trump will go 26th" and you can hear quite a few different things if you set your mind to it. Which of course makes it far more interesting.

What does it mean, what DID it mean, and was it just a prank?
