* Updated harckrf_gpio methods to more closely reflect hackrf_usb. Added some ui debug updates to RFFC5072 Status View. * Updated tuning tables for tuning.cpp. Remnoved 15MHz lower limit in max2831.cpp since lower bandwidths don't seem to be causing lower band issues. Added more opportunities for clocks to stabalize at startup in board.cpp. Added/amended UI to help with addresssing low band tuning issues. Cleaned up stale comments in radio.cpp. * Ran format-code.sh * Updated to remove commented lines as part of clean up addressing review comments. * Fixed clock_manager.cpp configruation for praline. Praline hackrf pro should have: CLK4: 6mA, Invert RFFC5072 40MHz ref and CLK5: 4mA, Invert MAX2831 40MHz ref. Improvements should be visible in the watefall at 2.4GHz, and between 2.311 and 2.599GHz. * After reviewin clock config, updated values to reflect: CLK0 MAX5864 (ADC) 40 MHz 4mA Normal Integer Minimizes sampling jitter for SNR. CLK1 iCE40 FPGA 40 MHz 6mA Normal Integer Stable timing for the SPI bridge. CLK2 LPC43xx MCU 40 MHz 4mA Normal Integer Standard reference for MCU PLL. CLK3 SMA Port P1 10 MHz 8mA Normal Integer Cleanest square wave for Ext Ref. CLK4 RFFC5072 (Mixer) 40 MHz 6mA Inverted Integer Crucial for PLL Lock stability. CLK5 MAX2831 (TRX) 40 MHz 4mA Inverted Integer Reduces phase noise in the 2.4GHz LO. CLK6 SMA Port P2 10 MHz 8mA Normal Integer Sync output for external gear. CLK7 Reserved Off N/A N/A N/A Disabled to save power/reduce EMI. * Ran format-code.sh * Moved fpga_brdige_init to portapack.cpp. This more closely resembles how hackrf_usb starts initializes the fpga, and allows time for the clocks to stabilize and facilitate locking to support low band tuning. * Ran format-code.sh * Added ProRadio Debug display to check for / debug locking. * Moved fpga_bridge_init before radio_init in portapack.cpp * Low band can now see signals. Updated clock_manager, rffc507 and portapack.cpp to ensure fpga intialized correctly. Ensures rffc507x.cpp has correct 40MHz reference frequency, prescaler, and synth configuration. * Updated radio to add q-invert on, dc-block on, and deimation=3 (8x, for 20 -> 2.5 MHz decimation for testing cleaner low band signals. * Ran format-code.sh
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:

How can I collaborate
You can write documentation, fix bugs and answer issues or add new functionality. Please check the following guide with details.
Consider that the hardware and firmware has been created and maintain by a lot of people, 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.
To support the people behind the hardware, please buy a genuine HackRF and PortaPack.
What if I really want something specific?
If what you need can be relevant in general, you can request a feature. Alternatively, go to our Discord by clicking the chat badge on top and discuss there.
What if I need help?
First, check the documentation. If you find a bug or you think the problem is related to the current repository, please open an issue.
