# 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/).

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).

As its name implies, HAVOC is a firmware made to have serious fun, mainly involving French systems (for now). Don't use it, we never did.

**In most countries, radio transmissions are tightly regulated. Transmitting without a licence or authorization, even at very low power, is certainly forbidden where you live. Always bear that in mind. You'll be the only one responsible for what you'll do with this software.**

Fork features:
* POCSAG 1200 receiver/decoder
* Simulate OOK frames from PT2262 encoders and friends (doorbells, remote outlets, ...)
* PWM audio RSSI output
* RDS (Radio Data System) PSN and Radiotext transmit
* Fully configurable AFSK transmit
* LCR (Language de Commande Routier) litteral message forming and transmit
* Xylos transmitter, street lighting control (NFM CCIR tones)
* Virtual keyboard or Unistroke "handwriting" text input
* "Play Dead" in case of emergency
* (Disabled for now) Close-Call™ style scanner
* (Disabled for now) Dynamic baseband code loading from SD card (see [wiki](https://github.com/furrtek/portapack-havoc/wiki))

Todo (highest to lowest priority):
* Fully configurable Jammer (fix)
* Whistle (tone generator)
* Play wave files from µSD
* Wireless microphone transmit
* CTCSS talkie transmit
* Frequency manager
* AFSK receiver
* EPAR transmit (old Xylos)
* POCSAG receiver
* POCSAG transmitter
* Detect/decode OOK
* Make SIGFOX interceptor work with all modules
* Number station
* Spectrum painter
* Rolling-code jam and replay trick

**Visit the [wiki](https://github.com/furrtek/portapack-havoc/wiki) for more details.**

About the PWM RSSI output: 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 (if enabled)...

Hardware is available at [ShareBrained Technology](http://sharebrained.com/portapack).
