This is an Iranian broadcast jammer which is commonly known as "Bubble jammer" due to its characteristic sound. It is used by the Iranian government to suppress Radio Farda and other shortwave and medium wave stations that broadcast news and other content to Iranian audience independently of the government. The jammer has been operational for more than a decade. In 2026 it has been very active during the Iranian protests and the subsequent US-Israeli attack on Iran.
