VFO Widget

VFO Widget

The VFO widget floats on the FFT display, attached to the active slice's VFO marker. It shows frequency, S-meter, and provides quick access to sub-menus.

Frequency Display

• Shows the current VFO frequency in MM.KKK.HHH format
• Double-click to type a frequency directly
• Accepts: 14.225 (MHz), 14225 (kHz), 14225000 (Hz), 14.225.000 (dotted)
• On XVTR bands: 1446 = 144.6 MHz (decimal inserted after 3rd digit)

S-Meter Bar

A horizontal bar below the frequency showing signal strength with scale markings (S1-S9, +20/+40/+60).

Sub-Menu Tabs

Click the labels at the bottom of the widget to open sub-menus:

🔊 Audio

• AF slider with mute toggle (speaker emoji)
• Pan slider (L/R) with center marker
• SQL — squelch enable + level slider
• AGC-T — AGC mode dropdown (Off/Slow/Med/Fast) + threshold slider

DSP

Mode-dependent DSP toggles:

• USB/LSB: NR, NB, ANF, NRL, NRS, RNN, NRF, ANFL, ANFT
• CW: NR, NB, APF, NRL, NRS, NRF (+ APF level)
• RTTY: NR, NB, NRL, NRS, RNN, NRF (+ Mark/Shift selectors)
• DIGU/DIGL: NR, NB, NRL, NRS, RNN, NRF (+ Offset selector)
• FM/NFM: OPT tab replaces DSP (CTCSS, repeater offset, duplex)

Mode

• Mode dropdown + 3 quick-select buttons (USB, CW, AM)
• Per-mode filter preset grid (4×2)

X/RIT

• RIT toggle + zero + step buttons + Hz display
• XIT toggle + zero + step buttons + Hz display

DAX

• DAX channel selector (Off, 1-4)

Slice Buttons

Floating beside the VFO widget, stacked vertically:

• ✕ — close the slice (removes from radio)
• 🔒 — lock the VFO (prevents tuning changes)
• ⏺ — record slice audio (pulses red while recording)
• ▶ — play recorded audio (disabled until recording exists)

Record & Play

The radio manages recording internally (up to ~2 minutes per slice). Press ⏺ to start recording, press again to stop. The ▶ button enables once a recording exists.

Voice keyer: To transmit recorded audio, press MOX first, then ▶. The radio routes playback to the TX path.

TX Badge

• Red "TX" — this slice is the active TX slice
• Grey "TX" — click to move TX to this slice
• Only visible inside the VFO widget
