# portapack-HAVOC HAVOC is a fork of the PortaPack H1 firmware, a portability add-on for the [HackRF One software-defined radio](http://greatscottgadgets.com/hackrf/). Hardware is available at [ShareBrained Technology](http://sharebrained.com/portapack). It is build on top of [ShareBrained's firmware](https://github.com/sharebrained/portapack-hackrf/), meaning that the original functionalities are kept (except when I don't sync for 2 months). As its name implies, HAVOC's functionalities can be fun (or mean). You shouldn't use them. We never did. **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 * Frequency manager (save/load from SD card) * "Soundboard" wave file player from SD card (put 8-bit mono files in /wav directory) * POCSAG 512/1200/2400 alphanumeric receiver/decoder * Simulate OOK frames from PT2262 encoders and many others (doorbells, remote outlets, some garage doors, ...) * Scheduled numbers station (for spies on a budget, alerts, LARP scenarios, fox hunts, ...) * Nuoptix DTMF sync transmit (quite specific but can be useful in some theme parks :) ) * RDS (Radio Data System) PSN and RadioText groups transmit * Fully configurable AFSK transmit (Bell202...) * Virtual keyboard or Unistroke "handwriting" text input * LCR (Language de Commande Routier) litteral message forming and transmit * "Xy" and "EP" transmitter, street lighting control (CCIR tones) * "Play Dead" in case of emergency * PWM audio RSSI output (for crude direction finding) # Progress Feature | Progress | Notes ------- | ------ | ----- Jammer | 95% | Need to make the different noise modes work RDS TX | 90% | Needs testing for Radiotext and audio mux function POCSAG RX | 90% | Still misses some messages Close-Call™ | 80% | Needs adjustments and optimization for wider frequency range EPAR TX | 60% | Older Xy, low priority Sigfox RX | 40% | Left aside, needs updates and testing Morse TX | 30% | Needs UI and testing Wave visualizer | 30% | High priority ADS-B TX | 30% | UI and frame gen stuff done Whistle | 20% | Easy IQ replay | 10% | High priority Generic TXs | 5% | Raw AX.25, AFSK, FSK, CCIR, DTMF... ADS-B RX | 0% | Could be fun Search | 0% | Will be a special Close-Call mode Scanner | 0% | Easy SSB TX | 0% | Requested PMR446 TX | 0% | Channel list, mic. in, PTT, CTCSS OOK RX | 0% | Mainly for 433MHz remotes POCSAG TX | 0% | Shouldn't be too tough, a real pager for testing would be nice AFSK RX | 0% | Shouldn't be too tough Analog TV TX| 0% | Could be fun Mic. TX | 0% | Need to find guard tones for various brands of wireless mics Painter | 0% | Spectrum painter, low priority # Screenshots ![HAVOC screenshots](screenshots.png) **Visit the [wiki](https://github.com/furrtek/portapack-havoc/wiki) for more details.** ## PWM RSSI output Huge kludge, wrote in a rush for direction finding. Audio frequency is 800Hz in NFM and 500Hz in WFM. The data path is very messy, the RSSI thread running on the baseband core sends groups of values to the application RSSI widget which computes the average value, which sends it back to the baseband module for audio output. ## Getting out of Play Dead mode Play Dead mode is a persistent fake error screen, which can be useful in case of situations where people become too curious. It's easily enabled, and disabled with a programmable key sequence (see Setup menu). If no exit key sequence was set up, it defaults to up-down-left-right. Enter the sequence and press select, you should see "Please reset" appear. After reset, you should be able to go back to the main menu. If not, a sequence was probably entered already. Solution hint: remove the backup battery for a few minutes, or ui_navigation.cpp ctrl+F 0x8D1 ;) This mode can also be used as a login screen, not requiring reset. # Thanks * Sig and cLx for research on AFSK LCR, Xylos, and for lending remote-controlled outlets * Rainer Matla for the donation :) * Keld Norman for ideas and suggestions # License Except where specified in subdirectories of this project, all work is offered under the following license: Copyright (C) 2013-2015 Jared Boone, ShareBrained Technology, Inc.
