New Weather Satellite Decoders:
– WeFax Receiver: A dedicated app for receiving and decoding HF Weather Fax transmissions.
– NOAA APT Receiver: A dedicated app for receiving and decoding NOAA APT weather satellite images.

Enhancements & Improvements
– Analog Audio App:
New Demodulation Modes: Added AM-FM and WFM-AM modes specifically for decoding weather satellite transmissions (WeFax and NOAA APT).
Waterfall Zoom: Added a “ZOOM x2” feature in AM and AM-FM modes for a closer look at the spectrum.
Settings Saved: Your preferred AM mode and zoom factor are now saved and restored on startup.

– BLE RX App:
MAC Vendor Lookup: The app can now use the new MACADDRESS/macaddress.db file on your SD card to identify the manufacturer of BLE devices.
Improved Stability: Refactored to use the new asynchronous USB messaging system, improving stability and performance.
Better Channel Hopping: Channel hopping is now sequential (37-38-39) instead of random, ensuring more consistent discovery.
Accurate Power Reading: The reported dBm value now correctly accounts for LNA and VGA gain settings.
UI/UX: Improved error handling, keyboard entry modes, and list clearing.

– ADSB Receiver:
Enhanced Decoding: Now decodes more frame types (DF4, DF5, DF20, DF21) to extract Squawk codes, more accurate altitude, and callsigns.
True Airspeed (TAS): The app can now calculate and display True Airspeed (TAS) from Indicated Airspeed (IAS) and altitude data.
Improved Logging: Logs now include more detailed information like Squawk, SIL, and vertical rate.
Beep on Packet: Added an option to beep whenever a valid ADSB packet is received.

– Signal Generator (SigGen):
Major Overhaul: The SigGen app has been completely revamped with new modulation types, including BPSK, QPSK, DSB, AM (50% & 100% depth), and Pulsed CW. This makes it a much more versatile testing tool.
Improved UI: The user interface has been updated to logically group modulation and shape options.
File Manager:
Improved Navigation: The directory listing and pagination logic has been completely rewritten for a smoother and more intuitive experience.
Waterfall Gradient Installer: When you open a .txt file from the new WATERFALLS directory, you’ll be prompted to install it as the new default waterfall color scheme.

– Capture App:
Your settings for capture rate, file format, and auto-trim are now saved and restored automatically.
UI & UX Improvements
Customizable Waterfall Colors: The Looking Glass and Search apps now use a customizable color gradient. Create your own waterfall.txt file in the WATERFALLS directory on your SD card to change the look!
New “Dark” Theme: A new theme has been added for those who prefer a darker interface.

– New Settings Menus:
Display: Control the new “Fake Brightness” feature and set your screen type (TFT vs. IPS).
Button Speed: Adjust the repeat delay, repeat speed, and long-press delay for the physical buttons.
Responsive UI: Many applications and widgets now dynamically adjust their layout to better fit different screen resolutions.
Improved Keyboard: The on-screen keyboard now defaults to the most logical mode (Alpha, Numeric) depending on the context.
New Icons: Added a huge number of new icons for all the new apps and features.

Under the Hood & For Developers
– External App Architecture: The firmware now supports loading and running applications from the SD card. This is a fundamental architectural shift that allows for greater flexibility and expansion.
– Build System: The minimum required CMake version has been updated to 3.16.
– Code Refactoring: Many internal apps have been moved to the new external app system, cleaning up the main firmware codebase. The de_bruijn.cpp generator has been removed in favor of more modern methods.

SD Card Content

New Directories:
– WATERFALLS/: Place your custom waterfall color gradient files here (e.g., aurora.txt, flame.txt).
– HOPPER/: Store your frequency lists for the new Hopper app here.
– MACADDRESS/: Place the macaddress.db file here for the BLE RX vendor lookup feature.
– SUBGHZ/: For Flipper-compatible .sub files.

New Files:
– Added example files for the new WATERFALLS and HOPPER directories.
– Added macaddress.db for BLE vendor lookup.
– Cleaned Up: Removed old and unused FREQMAN files.

New portapack mayhem app, Level app !

GullCode
Level app interface

The level app is as simple as possible and allow you to monitor available level meters in a single view.
There is a live graph of each RSSI values and power level.

HackRF Portapack Mayhem Firmware, Search/Freqman evolution branch

GullCode

On top of the existing ‘search and stay X seconds after a match’ the SearchApp have been updated with a ‘search and stay’ mode: stay while matching, leave after X seconds of inactivity, reset counters on activity during the wait. mode,
To use it just specify a negative value in the ‘wait’ field using the rotary encoder.

As some have some problems getting the bin back from discord, here you are:

Portapack firmware with Search App and updated Freqman files (based on latest next )

GullCode
  • I’ve build an up to date firmware with the last updates from next and the last version from search app and freqman enhancements.
  • The Search app is in the ‘receive’ menu
  • The documentation is here : https://github.com/GullCode/portapack-mayhem/wiki/Search
  • -Freqman now do understand freq files with that format:
    f=468000000 f=468000000,d=Single Freq f=468000000,m=AM,d=Single Freq AM f=468000000,m=NFM,d=Single Freq NFM f=468000000,m=WFM,d=Single Freq WFM f=468000000,m=AM,b=DSB,d=Single Freq AM DSB f=468000000,m=AM,b=USB,d=Single Freq AM USB f=468000000,m=AM,b=LSB,d=Single Freq AM LSB a=87000000,b=110000000 a=87000000,b=110000000,m=AM,s=100KHz,d=AM radio search a=87000000,b=110000000,m=AM,b=DSB,s=250KHz,d=AM radio search LSB a=87000000,b=110000000,m=WFM,b=16k,s=50KHz,d=WFM radio search s=50KHz r=430150000,t=430550000 r=430150000,t=430550000,d=HAM radio r=430150000,t=430550000,m=AM,b=DSB,d=HAM radio
  • The freqman GUI have note been improved and may show partial results on new formatted lines
  • Description of the fields:
    f=freq for one frequency or a=start_frequency,b=end_frequency for a range
    m=modulation
    b=bandwidth
    s=step
    d=description
  • All fields except ‘f=freq’ or ‘a=freqA,b=freqB’ are mandatory. If nothing specified actual value is used.
  • As a reminder :
    -Most of the time if the Search app is not working as you expected it’s coming from a SDCARD problem.
    -You need a SDCARD for the Search app to save settings between runs and between settings menu / main gui, and you need a SEARCH folder at the root of it.
    -Don’t forget to check that by default the ‘input: load’ fields in ‘search app -> params -> more ‘ are all checked.
    -You HAVE to click save in ordre to save the settings.
