via the ARRL: Secretive “Numbers Stations” Persist on HF

For many years, unidentified radio broadcasts have been transmitting coded messages, using numbers, such as “6-7-9-2-6. 5-6-9-9-0.” Even today, tuning across the HF spectrum typically will yield a “numbers station,” a mechanical-sounding voice (male or female) methodically announcing groups of single-digit numbers for minutes on end. According to Radio World, you may have tuned into a spy […]
