Maximize one panadapter to fill the main area¶

When you have more than one panadapter open, you can expand a single one to fill the entire main area, pushing the others aside temporarily.

Before you start¶

You must be connected to a FLEX-8600 radio.
At least two panadapters must be open. In single-pan mode the maximize button is hidden.

Steps¶

Locate the title bar of the panadapter you want to expand. It contains the slice name (for example, "Slice A"), followed by the ⬈, □, and × buttons on the right.
Click □ in that panadapter's title bar.

The selected panadapter expands to fill the main area.

Tips¶

To restore the multi-pan layout, click □ again on the maximized panadapter.

CW decode panel¶

The CW decode panel appears beneath the spectrum and waterfall when enabled. It displays decoded Morse text and provides controls for tuning the decoder.

Right-clicking anywhere in the decoded text area opens a context menu. In addition to the standard text actions (Select All, Copy, and so on), the menu contains a Clear entry. Click Clear to erase the entire CW decode buffer without leaving the text area. This is equivalent to clicking the CLR button in the panel toolbar.

TX-side decoded text¶

When both the radio's transmitted keying and received audio are routed to the same CW decode panel, your own sending appears in cyan (#5fc8ff) while incoming CW appears in the standard confidence-based colors. A single space separates Tx and Rx runs of text so they do not visually merge. No leading space is added when the panel is empty or when the first decoded text is from the transmitter.

Resizing the CW decode panel¶

In v26.7.4, you can resize the CW decode panel vertically to show more or less decoded text history. A thin horizontal drag grip appears at the top edge of the panel.

Move your cursor over the thin horizontal strip at the top of the CW decode panel. The cursor changes to a vertical resize cursor.
Click and drag down to make the panel taller, or up to make it shorter. The height is clamped between 60 and 600 pixels.
Release the mouse. The new height is persisted in settings and will be restored the next time you open the panel.

The font size of decoded text can also be adjusted independently (see Font size controls below).

Font size controls¶

In v26.7.4, two new buttons allow you to change the decoded-text font size:

Control	Type	Behavior
A- (Decrease)	Button	Decreases the decoded-text font size by 1 pixel, clamped between 8 and 32 pixels.
A+ (Increase)	Button	Increases the decoded-text font size by 1 pixel, clamped between 8 and 32 pixels.

Click A- to make the decoded text smaller.
Click A+ to make the decoded text larger.

The font size is persisted in settings and will be restored the next time you open the panel.

Notes¶

The CW decode panel requires PC audio routing to function. If audio is not configured the panel shows the reminder (requires PC Audio).
The Sensitivity slider maps values 0–100 to a cost threshold of 1.0–0.1. Higher values filter out lower-confidence decodes.
The Pitch range slider replaces the previous two separate Lo and Hi sliders. It provides a single double-handle control (range 300–1200 Hz) with the low end defaulting to 500 Hz and the high end defaulting to 700 Hz. The label "Pitch" is embedded within the widget.
The WPM range slider constrains the decoder's speed search range. It provides a single double-handle control (range 5–60 WPM) with the low end defaulting to 15 WPM and the high end defaulting to 40 WPM. The label "WPM" is embedded within the widget.
The Lock Pitch and Lock Speed toggle buttons freeze the decoder to the currently detected pitch or speed, preventing the decoder from tracking changes.
When the radio is transmitting, waterfall freeze is driven by the radio's interlock TRANSMITTING state across all connected clients (Multi-Flex), eliminating the 10–23 second TX-trail artifact after unkeying.
On radio reconnect, the desired panadapter FPS and waterfall line duration are reasserted to prevent silently dropping to the radio's 10 Hz default.
The panadapter title bar and CW panel now use theme-aware colors via ThemeManager::applyStyleSheet() instead of hardcoded hex values. The title bar gradient references {{color.text.disabled}} and {{color.background.1}}, the drag grip uses {{color.text.label}}, and the slice title uses {{color.text.secondary}}. The CW panel background and border use {{color.background.0}} and {{color.background.1}} respectively. The Sensitivity slider uses the applyPrimarySliderStyle() helper for consistent theming.
