portapack-HAVOC

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).

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™	70%	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	20%	UI and frame gen stuff done
Whistle	20%	Easy
IQ replay	10%	High priority
ADS-B RX	0%	Could be fun
Search	0%	Will be a special Close-Call mode
Scanner	0%	Easy
Generic TXs	0%	Raw AX.25, AFSK, FSK, CCIR, DTMF...
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

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.
