HAVOC banner

HAVOC is a fork of the PortaPack H1 firmware, a portability add-on for the HackRF One software-defined radio.

Hardware is available at ShareBrained Technology.

It is build on top of ShareBrained's firmware, meaning that the original functionalities are kept (except when I don't sync for 2 months).



If you want to submit a bug report, suggest something... Don't hesitate, use this page: (Check the progress list below first).


As its name implies, HAVOC's functionalities can be fun, mean and even useful sometimes. You shouldn't use them. No ! Bad ! Put it down.

In most countries, radio transmissions are tightly regulated. Transmitting outside of free/public bands without a licence or authorization, even at very low power, is certainly forbidden where you live. Always bear that in mind. You're the ONLY ONE responsible for what you do with this software.

Fork features

  • IQ file replay
  • Microphone FM transmit with CTCSS
  • CTCSS decoder
  • Frequency manager (save & load from SD card, with categories and notes)
  • File manager
  • "Soundboard" wave file player (put 8-bit mono files in SD card /wav directory)
  • ADS-B receiver with map view
  • ADS-B transmitter (aircraft spoof)
  • SSTV transmitter
  • Fully configurable jammer
  • POCSAG transmitter
  • POCSAG receiver/decoder
  • Morse transmitter (FM tone and CW)
  • OOK transmitter for common remote encoders (PT2262, doorbells, remote outlets, some garage doors, ...)
  • RDS (Radio Data System) PSN, RadioText and Time groups transmitter
  • Meteorological radiosonde receiver for M10 and M2K2...
  • AFSK receiver
  • AFSK transmitter (Bell202...)
  • Nuoptix DTMF sync transmitter (quite specific but can be useful in some theme parks :) )
  • TouchTunes jukebox universal remote (by Notpike)
  • LCR (Language de Commande Routier) message generator
  • Street lighting control transmitter (CCIR tones)
  • "Play Dead" in case of emergency
  • Fully configurable RF signal generator
  • RSSI audio output as pitch (for direction finding)


Feature Progress Notes
POCSAG RX   95% Needs support for numeric messages
Morse TX 95% Needs fox hunt scheduler and live keying mode
Mic. TX 95% Carrier leak bug, need to find guard tones for various brands of wireless mics
ADS-B RX 90% Needs angle and speed decoding
Close-Call™ 85% Needs adjustments and optimization for wider frequency range
ADS-B TX 85% Works but baseband module needs cleaning
SSTV TX 80% Needs better bitmap file handling, support for other modes (ROBOT ?) and callsign FSK ID
Radiosondes 75% Needs support for other models
Wave visualizer 70% Needs cleaning and handling of other sample formats, high priority
AFSK RX 70% Needs work regarding flexibility
Sigfox RX 40% Tuning basics done, needs decoding code and testing
Generic TXs 30% Raw AX.25, AFSK, FSK, CCIR, DTMF... Tonesets are ready
CC1101 TRX 10% And other sub-GHz transceiver chips like SI4032...
Scanner 0% Easy, could be used with POCSAG RX to catch jumping channels
SSB TX 0% Requested but math is hard :(
OOK RX 0% See if rtl_433's author is fine with using protocol defs
Analog TV TX 0% Enough CPU ? B&W and no sound ?
LoJack RX 0% Basically AFSK RX
DMR info RX 0% Retrieve DMR channel info. No voice because of vocoder complexity and possible legal issue
Tetra info? 0% Same
