PortaPack Mayhem

Nightly Release CodeScene Code Health GitHub All Releases GitHub Releases Docker Hub Pulls Discord Chat

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?

✔️ Static Badge The fabulous H4M complete or upgrade, featuring numerous improvements and accessories. Sold by our friends at OpenSourceSDRLab. Join their giveaways on discord (check the badge on top). EU customers can purchase via Lab401.

✔️ 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:

Where is the latest version?

The current stable release is on the GitHub release (latest by date) page. Follow the instructions you can find in the release description. The latest (nightly) release can be found here.
