Radio Free Europe/Radio Liberty:
A mysterious shortwave broadcast appeared on the first day of the US Iran war — a voice in Persian calmly reading random number sequences.
Radio enthusiasts believe it may be a numbers station, a type of spy radio station historically used to send encrypted coded messages to intelligence agents. These broadcasts were widely used by spies in the Cold War, allowing governments to communicate with operatives in secret.
RFE/RL captured this numbers station audio recording on March 10. Soon after, someone tried jamming the signal with electronic interference.
Numbers stations are considered Cold War spy tech, used by intelligence services like the CIA to communicate with agents around the world.
Is this mysterious signal connected to modern spying operations during the US Iran war?
Listen to the broadcast and decide for yourself.

Speaking of war-time communications, here is a new spin on the “The Thing” a.k.a. “The Great Seal Bug”

No magic here: some clever Russians were able to place a normally passive (non-powered) microphone and radio transmitter into the American Ambassador’s Moscow residence in 1952. Note that this circuit could evade evasion because it only emitted radio waves after receiving very powerful microwaves from a remote transmitter.
Sorry to be unrelated to topic – but more weird antiscience by the Federal Judiciary (is it really the 21st Century or have we gone back in time ?) . ………….
