The mobile FM radio jammer "P-US-ATFM" is designed to suppress FM signals in the frequency range from 76 to 108 MHz and allows you to jam any radio station operating in this frequency range. The jamming range depends on several factors and is about 25-50 meters (line of sight, without obstacles).

The device allows you to jam not only broadcast signals on the selected frequency, but also music played in MP3 format on this frequency. To do this, simply write the desired files to a memory card (not included) and install the card into the P-US-ATFM. The built-in battery allows you to use the jammer autonomously for up to 60 minutes. The jammer also works continuously when connected to the power supply.
