HackRF One PortaPack H4M — Portable SDR Transceiver Combo

The HackRF One with PortaPack H4M is the portable SDR setup featured extensively by Tech Minds (YouTube: @TechMinds2016), who produced a complete beginner's guide to the HackRF and PortaPack with Mayhem Firmware. The PortaPack H4M has become one of the most recommended HackRF PortaPack options — it surpasses the original PortaPack in quality and features at a lower price point.

The HackRF One covers 1 MHz to 6 GHz with both transmit and receive capabilities (half-duplex), making it useful for signal analysis, replay attacks, spectrum scanning, and learning RF fundamentals. The PortaPack H4M adds a touchscreen display and battery so you can run it completely standalone, without a PC. With Mayhem Firmware installed, you get access to a wide suite of RF tools including Meshtastic-compatible LoRa sniffing, POCSAG paging, NFC analysis, and much more.

• Frequency: 1 MHz – 6 GHz
• Half-duplex transceiver (transmit and receive)
