* Add SAME TX external app Adds a Specific Area Message Encoding (SAME/EAS) transmitter as an external app (.ppma) for HackRF PortaPack. SAME is the digital protocol used by NOAA Weather Radio and the Emergency Alert System in the US and Canada for broadcasting emergency alerts (tornado warnings, flash floods, EAN, etc.) on 162.400-162.550 MHz and AM/FM broadcast stations. Features: - Originator code selector (WXR, EAS, CIV, PEP) - Event code selector: 26 standard SAME event codes (RWT, TOR, SVR, FFW, EAN, etc.) with live name display - FIPS location code entry (state 00-99 + county 000-999) - Purge time entry (hours + minutes) - Live message preview showing the encoded header - AFSK encoding: mark=2083Hz, space=1563Hz, 520.833 baud - FM deviation: 5 kHz, repeated 3x per SAME spec - Default frequency: 162.550 MHz (WX channel 7) Protocol details: - 16-byte 0xAB preamble (bit-reversed for LSB-first AFSK) - Header: ZCZC-ORG-EVT-SSPCCC+HHMM-JJJHHMM-STATION- - Uses existing PAFT (proc_afsk) baseband image * Apply clang-format via format-code.sh * Add GPL license headers, guard re-entry, call set_transmitting(true) - Add standard PortaPack GPL-2.0 license header to ui_same_tx.cpp and .hpp - Guard start_tx() with tx_active_ to prevent re-entrant calls - Call tx_view.set_transmitting(true) after starting TX so the TransmitterView button switches to stop mode
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.

✔️ 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:
