If they used a older-style dictation machine based on tape then you could detect the electromagnetic transmissions from the dictation machine when it was recording. But how would you detect if someone was secretly recording with an MP3 player that recorded to flash memory? Is there some transmission which could be detected? Perhaps some low power ultra high frequency from chip refresh cycles? 3 AM with the right equipment it would be findable , now are you serious or just another one of "them"? Nope, I am not one of "them". This is very much for real. What is "3 AM". Your kidding ? do you read analogue clocks ? |
