P-US-ATFM FM Broadcast Jammer – Portable Radio Signal Blocker with MP3 Override

The P-US-ATFM FM broadcast signal blocker operates across the 76 to 108 MHz frequency band — the standard FM radio range. It can suppress radio stations within a 25–50 meter radius (in open space) and allows you to broadcast custom audio on a selected FM frequency via microSD card.

🎶 How It Works

1. Set your desired FM frequency using the LCD screen.
2. Once activated, the jammer emits a silent signal on that frequency, effectively muting any station.
3. Want to broadcast your own content? Just load MP3 files onto a microSD card (up to 32 GB) and insert it into the device — your custom audio will replace the radio signal.
