[1][2] It broadcasts short, repeated beeps at a rate of around 50 per minute, for 24 hours per day.
The Pip has been active since 1986, when its distinctive beeping sound was first recorded by listeners, and is a sister station to UVB-76.
The station is commonly referred to as "The Pip" among English-speaking radio listeners.
[2] Radioscanner.ru identifies the owner of this station as a North-Caucasian military district communication center with callsign "Akacia" (ex-72nd communication center, Russian "72 узел связи штаба СКВО").
Examples include: "Для ЙХЬЙ ЗЬ1Б НИ9В ДМЦ3 49ФТ Ц2ЗА ЛИ27 ИННЦ ЩГЙП 8ЦЩЙ (To JH'J Z'1B NI9V DMC3 49FT C2ZA LI27 INNC ShchGJP 8CShchJ)" This is then followed with another "To" and then the callsigns are repeated again, concluding with Как слышно?
It is often suggested that The Pip is part of a larger radio relay or control system, which also includes The Buzzer and The Squeaky Wheel, which both follow similar formats.
In particular, activity on The Pip often used to be followed a few minutes later by a voice message on The Squeaky Wheel, suggesting that both are operated by the same organization and share the same purpose.
[2] On one occasion, The Pip's characteristic beeping sound could be heard in the background while a message was being transmitted on the Squeaky Wheel's frequency, which may indicate that both stations are even operated from within the same building or room.
"Kolos" was the callsign of the North Caucasus Military District's 800th Notification Network.
Due to boredom and a lack of certainty about reception (e.g. in case of wrong tuning), one day an information service ensign suggested an enhancement: to create a marker generator which would help recipients to tune to the 800th Network's frequency.
The enhancement suggested was approved, and the ensign was celebrated for his idea by being put into the "Achievement Desk of the Staff for Glory Expression."
Then, while I was on practice there, I assembled the second version of the marker generator, built on a real PCB, which then began operation at the receiving site: the 72nd Communication Hub.
