sBitx Commands Reference

This feature is currently experimental and intended solely for developer use.

The sBitx supports both visual and text commands to control its functionality. Text commands can be entered in the native UI by preceding the text with a backslash (\) or by pressing the CMD key on the on-screen keyboard. In the web UI, press the CMD button at the bottom of the page to open the Command Console and enter commands directly without using a backslash.

Basic Radio Commands

  • `MYCALLSIGN [text]` – Sets your operator callsign. Update this if another user operates the radio so that macros, FT8, and the logger function properly.
  • `MYGRID [6 letters]` – Sets your location’s Maidenhead grid, updated if the station’s location changes.
  • `FREQ frequency` – Sets the radio’s operating frequency. Frequency can be in Hz or KHz; you may use `f` for short (e.g., `FREQ 7035` or `f 7035000`)
  • `AUDIO 0-100` – Adjusts the audio volume of received signals.
  • `MODE [USB/LSB/CW/CWR/FT8/DIGITAL/2TONE/etc.]` – Selects an operational mode; `m` can also be used as a shortcut.
  • `AGC OFF/SLOW/MED/FAST` – Configures Automatic Gain Control, ideal for SSB on SLOW, CW on FAST/MED, and OFF for digital modes.
  • `DRIVE 1-100` – Controls transmit power output.
  • `STEP 10K/1K/100H/10H` – Determines the frequency increment when using the tuning knob.
  • `SPAN 25K/10K/6K/2.5K` – Sets spectrum and waterfall width.
  • `RIT ON/OFF` – Activates Receiver Incremental Tuning for slight frequency shifts.

Advanced Commands and Control

  • VFO Controls: `VFO A/B` to toggle between two VFOs for frequency hopping.
  • Bandwidth: `BW 50-5000 (Hz)` defines audio bandwidth.
  • Frequency Offset: `RIT_DELTA -25000 to 25000 (Hz)` sets RIT offset.
  • Transmission Control: `ESC` aborts transmission; `TX` and `RX` switch to transmit and receive, respectively.

Band Controls
Select a specific band: `10M`, `12M`, `15M`, etc., will toggle within that band.

Recording and Logging

  • REC ON/OFF` begins or stops recording audio to a WAV file.
  • LOGGER` commands (`ESC`, `MACRO`, `CALL`, `SENT`, `RECV`, `EXCH`, `LOG`, `WIPE`, etc.) manage logbook entries and macros.

SSB, CW, and FT8 Specific Controls

  • SSB Controls: `MIC 0-100` sets microphone gain.
  • CW Controls: `WPM`, `PITCH`, `CW_DELAY`, and `SIDETONE` configure CW characteristics.
  • FT8 Controls: Adjust the frequency, set auto-reply options, and select repeat count for CQ messages.
  • Telnet Commands: Set and control telnet sessions with commands like `TELNETURL`, `topen`, and `tclose`.
