* Add new jammer modes Overview: This PR enhances the PortaPack Jammer app by introducing eight new signal types, ported from my Flipper Zero RF Jammer app (https://github.com/RocketGod-git/flipper-zero-rf-jammer). These modes expand the app's capability to disrupt a wide range of RF communication protocols, from analog radios to modern digital systems. The implementation preserves the original app structure, resolves namespace conflicts, and ensures compatibility with the Mayhem firmware. New Modes The following modes have been added to the options_type in ui_jammer.hpp, with corresponding signal generation in proc_jammer.cpp: Noise: Generates broadband white noise to interfere with analog and digital signals (e.g., Wi-Fi, Bluetooth, key fobs). Highly effective for overwhelming receivers across a frequency range. Sine: Produces a continuous, unmodulated sine wave to jam narrowband receivers, ideal for analog FM/AM radios or telemetry systems. Square: Emits a harmonic-rich square wave, disrupting digital protocols (e.g., OOK, ASK) and systems sensitive to sharp transitions, such as remote keyless entry. Sawtooth (Experimental): Generates a sawtooth wave with a unique harmonic profile, useful for testing interference against PWM-based or niche analog systems. Triangle (Experimental): Creates a triangle wave with minimal harmonics, suitable for exploratory jamming of narrowband systems or receiver linearity testing. Chirp: Outputs a rapid frequency-sweeping chirp signal, effective against frequency-hopping and spread-spectrum systems (e.g., some Wi-Fi, Bluetooth, or military radios). Gauss: Generates Gaussian noise to mimic natural interference, targeting digital systems like GPS or data links by degrading signal-to-noise ratios. Brute (Experimental): Transmits a constant maximum-amplitude signal to saturate simple receiver front-ends, useful for brute-force jamming of basic analog devices. * Fixed and made brutal. This PR introduces user-focused improvements to the Jammer App in the HackRF PortaPack Mayhem Firmware, enhancing usability and flexibility. The changes address specific user requirements for a more intuitive default configuration, continuous waveform support, and dynamic setting adjustments during transmission.
PortaPack Mayhem
This is a fork of the Havoc firmware, which itself was a fork of the PortaPack firmware, an add-on for the HackRF. A fork is a derivate, in this case one that has extra features and fixes when compared to the older versions.

Frequently Asked Questions
This repository expands upon the previous work by many people and aims to constantly add new features, bugfixes and generate documentation to make further development easier. Collaboration is always welcomed and appreciated.
What to buy?
✔️ 
✔️ A recommended one is this PortaPack H2, that includes everything you need with the plastic case "inspired" on this.
✔️ Some individuals lean towards the H2 with a metal enclosure, but its advantages remain debated. Share your insights on our wiki.
⚠️ Be cautious , ask the seller about compatibility with the latest releases. Look out for the description of the item, if they provide the firmware files for an older version or they have custom setup instructions, this means it might be NOT compatible, for example:
⚠️ If it looks too different, this might mean that they are using their own recipe, check the different models in our wiki. For example all the H3 and clones of that version use their own version of the firmware. They do not contribute the changes back and eventually you will be left with a device that nobody maintains:
