in the 80s, the soviets gifted a US embassy with a big wooden plaque that had the american eagle on it, like the back of a quarter. Inside was a listening device. It had no batteries and could switch off and on remotely. So we would scan for bugs, they would hear us and turn it off..... since it had no power source and was off, we would not detect it. Then they would turn it on a little later and continue listening after they thought we finished scanning.

Took a while to figure it out I hear.
lol

These things existed in the 80s.....maybe sooner.

Considering how undetectable a bug like this is and how it is largely unknown to the public and how long its been around, 70 years about, I wouldn't be surprised if these were common and all over the place right under everyones noses.
