# PortaPack Mayhem
[](https://github.com/portapack-mayhem/mayhem-firmware/actions/workflows/create_nightly_release.yml) [](https://codescene.io/projects/8381) [](https://github.com/portapack-mayhem/mayhem-firmware/releases) [](https://github.com/portapack-mayhem/mayhem-firmware/releases/latest) [](https://hub.docker.com/r/eried/portapack) [](https://discord.gg/tuwVMv3)
This is a fork of the [Havoc](https://github.com/furrtek/portapack-havoc/) firmware, which itself was a fork of the [PortaPack](https://github.com/sharebrained/portapack-hackrf) firmware, an add-on for the [HackRF](http://greatscottgadgets.com/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](https://github.com/portapack-mayhem/mayhem-firmware/wiki/How-to-collaborate) is always welcomed and appreciated.
## What to buy?
:heavy_check_mark: A recommended one is this [PortaPack H2](https://grabify.link/7T28JP), that includes everything you need with the plastic case "inspired" on [this](https://github.com/portapack-mayhem/mayhem-firmware/wiki/H2-Enclosure).
:heavy_check_mark: Some individuals lean towards the [H2 with a metal enclosure](https://grabify.link/HTDXG5), but its advantages remain debated. Share your insights on our [wiki](https://github.com/portapack-mayhem/mayhem-firmware/wiki/Hardware-overview).
:heavy_check_mark: Our friends at OpenSourceSDRLab give away five units every three months in our discord (check the badge on top) of one of their [PortaPack H2 bundle](https://grabify.link/T328XL) or [only metal case kits](https://grabify.link/LG0OUY), you can support them too by ordering.
:warning: 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:
:warning: If it looks **too different**, this might mean that they are using their own recipe, check the [different models](https://github.com/portapack-mayhem/mayhem-firmware/wiki/PortaPack-Versions) 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:
## Where is the latest version?
The current **stable release** is on the [](https://github.com/portapack-mayhem/mayhem-firmware/releases/latest) page. Follow the instructions you can find in the release description. The **latest (nightly) release** can be found [here](https://github.com/portapack-mayhem/mayhem-firmware/releases/).
## How can I collaborate
You can write [documentation](https://github.com/portapack-mayhem/mayhem-firmware/wiki), fix bugs and [answer issues](https://github.com/portapack-mayhem/mayhem-firmware/issues) or add new functionality. Please check the following [guide](https://github.com/portapack-mayhem/mayhem-firmware/wiki/How-to-collaborate) with details.
Consider that the hardware and firmware has been created and maintain by a [lot](https://github.com/mossmann/hackrf/graphs/contributors) of [people](https://github.com/portapack-mayhem/mayhem-firmware/graphs/contributors), so always try collaborating your time and effort first. For coding related questions, if something does not fit as an issue, please join our Discord by clicking the chat badge on [top](#portapack-mayhem).
[](https://github.com/portapack-mayhem/mayhem-firmware/graphs/contributors)
To support the people behind the hardware, please buy a genuine [HackRF](https://greatscottgadgets.com/hackrf/) and [PortaPack](https://store.sharebrained.com/products/portapack-for-hackrf-one-kit).
## What if I really want something specific?
If what you need can be relevant in general, you can [request a feature](https://github.com/portapack-mayhem/mayhem-firmware/issues/new?labels=enhancement&template=feature_request.md).
You can create a bounty and invite people to your own bounty. This will incentivize coders to work on a new feature, solving a bug or even writting documentation. Start a bounty by [creating](https://github.com/portapack-mayhem/mayhem-firmware/issues/new/choose) or [choosing](https://github.com/portapack-mayhem/mayhem-firmware/issues/) an existing issue. Then, go to [Bountysource](https://www.bountysource.com/) and post a bounty using the link to that specific [issue](https://www.bountysource.com/teams/portapack-mayhem/issues).
Promote your bounty over our Discord by clicking the chat badge on [top](#portapack-mayhem).
Bountysource has not been reliable lately, so until this changes, please **DO NOT** post a bounty there. Go to our Discord by clicking the chat badge on [top](#portapack-mayhem) and discuss there.
