Workspaces, templates, and presets

Choose what to save according to how much of the receiver you want to restore.

Workspaces

Use the workspace name in the top bar to switch, create, or delete workspaces. The first workspace in a new database contains a Device, Scope, and Speaker. Later workspaces start empty.

Changes are saved on the server, including node positions, rack layout, and band-plan region. All connected clients share one active workspace.

Export and import

The ↓ button beside a workspace downloads a JSON file containing its name, patch, rack, band-plan choice, and node settings. The file excludes the database ID, revision, and undo history.

Import a workspace file creates and activates a new workspace. It never overwrites an existing one; duplicate names receive a copy number. Available radios are opened with the imported settings. Missing radios appear in the apply report, and their Device nodes wait for them. Select a replacement radio to use different hardware.

Files from a newer, unsupported format version are rejected.

Undo and redo

Use the top-bar arrows, Ctrl/⌘ Z, or Ctrl/⌘ Shift Z. Each workspace stores its last 100 layouts on the server, so undo and redo affect every connected client. Editing after undo discards the redo history.

Undo also updates the running graph. Undoing an added channel closes it; redo recreates it with its saved settings. Radio tuning is excluded from this history.

Copy and paste

Ctrl/⌘ C copies selected nodes and the wires between them. Ctrl/⌘ V pastes and selects the copies beside the originals. Repeated pastes are offset so they remain separate.

Connections to nodes outside the selection are excluded. A copied Device has no radio assigned; select one before using it. The clipboard lasts for the browser tab’s lifetime and works across workspaces.

Templates

Select a Device, then open Library → Templates. Applying a template immediately retunes that radio, sets its sample rate, and merges channels and compatible displays or outputs into the workspace. The apply button identifies the target radio.

Templates cover broadcast FM, airband, ADS-B, ACARS, AIS, APRS, paging, NAVTEX, radio clocks, GNSS, marine VHF, PMR446, digital voice, ISM, DAB, and common amateur bands. Templates that the selected radio cannot tune or sample are disabled.

Undo removes the added nodes, but does not restore the radio’s previous tuning or sample rate.

Presets

Save a preset after arranging and tuning a workspace. Applying it restores the graph and device settings using durable radio identities where available. The apply report lists anything that could not be restored.

Presets are editable and stored in the server database. Templates are read-only and ship with the app.

Bookmarks and band plans

A bookmark saves a frequency and label. Applying it tunes the selected Device and keeps the graph.

Bands searches the active regional allocation data. Choose the region from the workspace menu and enable the allocation ruler on Scope nodes if needed. Hover over the ruler for allocation details; click to tune, using the band’s usual mode when the data includes one.

Automatic region detection uses browser location and requires HTTPS or localhost. You can always choose the region manually.
