The Radio Setup dialog is the master per-radio configuration window. It contains tabs for radio information, network settings, GPS, TX configuration, Phone/CW, RX calibration, audio, antenna names, filters, transverters, USB cables, peripherals, serial ports, APD, themes, and SmartLink pinned certificate management.
Chassis serial number. Click the copy button next to the value to copy the serial number to the clipboard.
Region
Regulatory region (USA by default).
HW Version
Hardware version string.
Options
Licensed radio options.
FlexControl
Detected state of FlexControl hardware.
multiFLEX
multiFLEX enabled state.
Model
Radio model.
Each read-only value field has a copy button. Click the clipboard icon to copy the value to the system clipboard. A brief "Copied" popup confirms the action. Copy buttons are visually dimmed when the value is empty or unavailable.
The License Info section displays subscription status, expiration date, radio ID, and licensed version. Each field includes a clipboard copy button next to the value.
Opens a file dialog for a SmartSDR installer (.msi, .exe) or pre-extracted .ssdr firmware file. Passes the selected path to FirmwareStager which extracts .ssdr payload and emits progress.
Upload Firmware
Starts firmware upload with progress bar and status.
Firmware status
Empty until a firmware upload begins, then shows progress and result text.
Only enabled when the radio is connected. Clicking shows a confirmation dialog. On WAN/SmartLink connections, you must reconnect manually after the radio finishes booting. On LAN connections, AetherSDR automatically reconnects. The dialog closes after reboot is initiated. New in v26.6.3 (#3334).
The SmartLink tab manages pinned SmartLink TLS certificates. Lists each pinned certificate with host, SHA-256 fingerprint, and pinned date. Cert-pin mismatch now hard-pauses the handshake with a modal dialog.
Open Settings > Radio Setup... and click the RX tab.
Enter a known-accurate reference frequency in Cal Frequency (MHz):.
Click Start. The button changes to Busy and is disabled while calibration runs. A status label to the right of the button shows progress text.
"Starting…" appears immediately.
If you leave the Cal Frequency (MHz): field empty and click Start, the status label shows "Enter cal frequency" in amber and the calibration does not start.
Wait for the status label to indicate completion. The Start button re-enables automatically.
Confirm or adjust the result using Freq Offset (ppb):.
Control
Description
Notes
Cal Frequency (MHz):
Frequency used for calibration, entered in MHz to six decimal places.
Sent to the radio as radio set cal_freq=<value>.
Start
Begins the calibration sweep. Disabled and labelled Busy while a calibration is in progress.
Resets freq_error_ppb to 0 before starting. Requires a non-empty cal frequency.
Freq Offset (ppb):
Manual frequency offset correction in parts per billion.
Selects oscillator reference source. Options shown depend on hardware installed.
Lock status (Locked / Unlocked) is shown alongside the combo and updates live. When Auto is selected and the radio has resolved to a specific source, the label shows "Auto -> " to indicate the active hardware. If an External 10 MHz source is selected but no external signal is detected, the label appends "(not detected)". The label reads "Waiting for oscillator status" until the radio reports its first oscillator state.
