 URL parameters can be used to trigger an "embedded" mode which hides the headers, footers and settings. In this mode, you provide configuration for the various filter and display options via additional URL parameters. Any settings that the user has set for Spothole are ignored. This is so that the embedding site can select, for example, their choice of dark mode or SIG filters, which will not impact how Spothole appears when the user accesses it directly. Effectively, it becomes separate to their normal Spothole settings.

 By default, all outdoor programme providers are enabled, as is one cluster node and the NG3K DXpedition data. The RBN spot providers are turned off by default due to the volume of traffic from CW/RTTY/FT8 skimmers, and the APRS and Packet spot providers are off by default on the assumption that Spothole users want a spot with a human at the other end of it, but all can be easily re-enabled.
