Settings - posssss/portapack-mayhem GitHub Wiki

This section provides a set of utilities that can be used to configure some aspects of the PortaPack and are described below. Settings are saved in persistent memory.

Audio

This allow the setting of the tone Key mixer setting as a percent of the audio level.

Radio

In the radio section there are two options,

  1. One for turning on/off the External Clock.
  2. Second item is turning on or off the Antenna Bias Tee.

User Interface

The UI interface setting for the following can be Enabled (tick) or Disabled (x) or selected value for the backlight timeout:

  • Backlight off after 5 seconds( default) or can be set to 5,15,30 seconds or 1,3,5,10 minutes.
  • Show the Splash screen at power-up.
  • Show the clock - This allows the date and time to be updated by moving the cursor to the select item and use the rotary knob to adjust the value.
  • Back button in menu - Enables a "Back" button on all menu screens.
  • Show/Hide Status Icons - Select which status bar icons are visible or hidden.

Date/Time

Set the date and time.

Calibration

This provides an app for the calibration of the screen and alignment by following on screen instruction.

You have to keep pressed for at least a second on each target for the app to guess the touch area correctly and show next target on release.

App Settings

Allow to specify if you want to load / save application settings at app start/end. App settings are saved in the /SETTINGS folder.

  • Load app settings
  • Save app settings

Converter

PortapackConverter

Set up convert or down convert mode. Widgets:

  • show / hide icon, hiding will also disable any up / down conversion
  • enable / disable converter
  • (+) or (-) set the offset sign
  • set the offset

When using an upconverter it's common to use an offset to access the correct frequency. As an example, if you want to use a HamItUp which is designed to listen from 60KHz to 30MHz, you'll need to tune your portapack to 125 MHz (or any other frequency used in the upconverter local oscillator) + the frequency you need.

Doing the calculation and tuning while adding the frequencies can be a bit tedious. Don't worry: just got into your portapack's settings, Radio menu, and set the shifting you need. You can set up conversion (+) or down conversion (-) in the Settings/Converter menu.

When the option is on, the displayed frequency is the one you want to tune in, and the real tuned frequency is displayed frequency plus or minus offset. When the option is off, the displayed frequency is the one you want to tune in, and the real tuned frequency is the displayed frequency.

You can turn it on and off using the checkbox while in Radio menu, or using the top bar icon 'Freq', with an arrow telling you if it's up or down conversion.

Note: This has the same effect as using the top bar 'Freq' icon. While in the radio menu, the synchronisation of the top bar 'Freq' status and the checkbox is not implemented when toggling the top bar 'up' icon. The status is saved, and the last to talk is setting the status.

QR code

Set the size of the displayed QR code in the RadioSonde app.

  • show larger or not

P.Memory Mgmt

PORTAPACK_PMEMTOSDCARD

Set persistent memory from/to sd card options. It's particularly useful to keep different default settings than those configured by the firmware if there is no/dead coin battery. Information messages will be displayed at each widget trigger. If loading at startup is failing, it will not show any message, the boot may continue like nothing happened. Widgets:

  • use sdcard for pmem: if checked the firmware will try to load last saved settings at startup. The checkbox is configuring a flag file under SETTINGS for it to work without coin battery. Each time you correctly exit an app using the back button, it's persistent settings, if any, are saved to the sdcard.
  • save p.mem to sdcard : save actual persistent memory onto the sdcard
  • load p.mem from sdcard : manually load persistent memory from sdcard
  • !reset p.mem, load defaults! : reset the persistent memory to defaults

FreqCorrect

PORTAPACK_FREQCORRECTION

Set TX and or RX Frequency correction in Hz.

A value between [-4,+4] MHz of correction is accepted, else it's truncated due to the variable used in persistent memory.

Use the '+' or '-' filed to change to correction mode (addition or subtraction ).

Use the MHz RX and MHz TX field to set the correction in each mode.

Settings are automatically saved in persistent memory.

Encoder Dial

Allows the sensitivity of the encoder dial to be adjusted between Low, Normal, and High.
