* Fix for #2538 Fix for #2538 Added on_bandwidth_changed Callback to ui_transmitter.hpp Modified the field_bw.on_change lambda in the TransmitterView constructor to trigger the on_bandwidth_changed callback Connected the Callback in ui_siggen.cpp I am not a C++ programmer so this change was proposed by Gemini AI. I have built and tested the App and it works as expected and I don't think the change will have any unexpected side effects. * Fix clang issues Fix clang issues * Update ui_transmitter.cpp typo * Revised change The proposed change mirrors the way a change to the frequency (on_edit_frequency) is triggered in ui_siggen by the tx_view. The bw parameter is not passed because it is stored in _setting in the tx_view and will be read by update_config. A change to the bw is not checked against auto_update to keep its behaviour consistent with a change to the gain, amplitude or frequency. * Make changes to the channel_bandwidth dynamic whist playing Behaviour of channel bandwidth is now consistent with frequency, amp and gain. * comment edit * revert hackrf submodule checkpoint to the repo * comment --------- Co-authored-by: zxkmm <zxkmm@hotmail.com>
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.

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:
