Huge flaw” threatens US emergency alert system, DHS researcher warns!

“I am often asked how radio works. Well, you see, wire telegraphy
is like a very long cat. You yank his tail in New York and he
meows in Los Angeles. Do you understand this? Now, radio is
exactly the same, except that there is no cat.”
-Attributed to Albert Einstein, but I ripped it from the latest Splatter .PDF March 2025 issue.

I don't know how "huge" this is.  The encoder with the vulnerability is a low-end encoder bought by folks that were too cheap to buy a Sage, and probably don't check their logs anyway.  I believe that the commission revoked the type acceptance to those units years ago, deeming them illegal to use in a FCC licensed station in the first place.

No worries.   This is the same Moscow that thought their "special operation" in Ukraine would be a 2 week cakewalk.

Never fear about both this EAS tech glitch and those pesky Russki missiles, as Space Force will protect us, right Pigmeat?
