Unlock the hidden world of wireless signals with the PortaPack H4M, loaded with powerful Mayhem firmware. Designed for SDR hobbyists, pentesters, and ham radio operators, this compact kit transforms your HackRF One into a touchscreen-equipped radio lab. No need for a computer — scan, capture, decode, and replay frequencies from 1 MHz to 6 GHz anytime, anywhere. With professional-grade features in a rugged portable shell, it’s the ultimate tool for field and lab use.

Key Features

  • Full SDR receiver kit with 3.2″ touchscreen, rotary controls, and built-in battery.

  • Supports 1 MHz–6 GHz wideband scanning, signal decoding, replay, and spectrum analysis.

  • Mayhem firmware suite includes RF capture & replay, ADS‑B, BLE/Wi‑Fi sniffing, pagers, TPMS, and more.

  • Portable design with USB‑C charging, microSD logging, GPIO expansion, and durable ABS housing.

Why Choose Our PortaPack H4M Mayhem Standalone SDR Receiver Kit
Unlike PC‑dependent SDR setups, this self‑contained kit offers instant, on‑the‑go radio exploration. Mayhem firmware provides a richer app suite compared to earlier H2 packs, while the hardware upgrades (touchscreen, battery, GPIO) deliver unmatched portability and customization. It’s a premium SDR experience wrapped in a pocketable, field‑ready unit.

Perfect For

  • RF enthusiasts and ham radio operators

  • Cybersecurity pentesters performing wireless reconnaissance

  • Students and educators exploring radio frequencies hands‑on

  • Field engineers needing fast, portable spectrum analysis

How It Works

  • Attach to your HackRF One via GPIO/SMA connections.

  • Power on and browse Mayhem apps — from RF Capture to Spectrum Analyzer.

  • Insert a microSD for recording or replaying signals.

  • Use touchscreen and rotary knob for real‑time control.

    Beautiful dress
    Really happy with this purchase. I only wish I had steamed it before trying it on because it arrived with a few wrinkles from shipping.

    Worth every dollar
    The quality surprised me. The material has a nice weight and doesn't feel see-through at all. I'll definitely order another style.

    Runs slightly roomy
    I was between sizes and ordered the larger one. It still looked great, but I probably could have gone with my usual size.

    Lovely dress
    The zipper was a little stiff the first time, but after wearing it once everything worked perfectly. Overall, I'm very happy.
