Полный редизайн накладки поверх спектра: шапка (слайс-бейдж A/B, ширина фильтра, кликабельный SPLIT, индикатор TX), метр-ряд (индикаторы NR/NB/ANF/ SNB + сигнал-бар), крупная частота + S, нижний бар с fly-out пикерами. - Fly-out движок MODE/DSP/AUD (раскрываются под баром, карточка растёт): MODE — сетка режимов 4×2 + фильтры; DSP — NR/NB/SNB/ANF + AGC; AUD — выбор аудио-устройства вывода (задел под слайсы). - Слайдер громкости (click+drag) + mute; SPLIT-toggle; live TX-индикатор. - Все контролы подключены к RadioController (SetVolume/ToggleMute/SetSplit/ EnumOutputDevices→ApplyAudioDevice); wire в MainForm + HandleMouseUp, чтобы клик по накладке не уходил в спектр. - FormatFreq на Int64 (double накапливал ошибку в десятки Гц на ~10 ГГц QO-100). - S-метр ниже по высоте + плавный градиент по уровню dBm: тёмно-зелёный→ зелёный→жёлтый→красный (красный к ~S9+18). - Кэш+dirty рендер сохранён (CPU-паритет со старой накладкой), GL-путь через DrawOverlayBitmap.

TVfoOverlay — накладка-«флаг слайса» поверх спектра, стиль SmartSDR.
|
||
Компоновка (сверху вниз):
|
||
шапка : [A] 2.7k SPLIT [TX]
|
||
метр : NR NB ANF SNB ▂▃▅▇█▆▄ -20 +20 +40
|
||
частота : 7.125.000 S 7
|
||
бар : 🔊──○── MODE DSP AUD
|
||
Нижний бар компактный; клик по MODE/DSP/AUD раскрывает fly-out панель ПОД баром
|
||
(карточка растёт в высоту). Слайдер громкости — click/drag по треку.
|
||
Рендер: кэш-битмап (BlendBitmapKey с key-color) + dirty-флаг, как раньше.
