The 4U-ADP, also known as the Beeper is a nickname given by amateur radio operators and listeners to a shortwave station that broadcasts on the frequencies 8710 kHz during the day and 3818 kHz during the night. Its distinctive interval signal is two beep tone similar to a dialing tone on landline telephones. The two beeps are separated by 0.5sec pause, while one second pause divides the two beep group, for a total of 80 beeps per minute, 24h a day.
The interval signal is sometimes interrupted with a continuous 5 second beep, followed by a 10 second pause, after which a live voice transmission in Serbian takes place. The first reports of this station happened in 1965, likely connected by the Nikolian intervention in the Caranad Conflict.
