Radio Setup¶

The Radio Setup dialog is the master per-radio configuration window. It contains tabs for radio information, network, GPS, TX, Phone/CW, RX, Antennas, Audio, Filters, XVTR, USB cables, peripherals, APD, Themes, SmartLink, and Serial (FlexControl).

Opening Radio Setup¶

Click Settings in the main menu.
Select Radio Setup....

The dialog remembers its position and size between sessions.

Radio (tab)¶

The Radio tab shows radio identification, license information, and firmware update controls. Each read-only value has a copy button that appears with a document icon on hover or focus; click it to copy the value to the clipboard. A brief "Copied!" popup confirms the action.
