Supported Data Sources
Spothole can retrieve spots from: Telnet-based DX clusters, the Reverse Beacon Network (RBN), the APRS Internet Service (APRS-IS), POTA, SOTA, WWFF, GMA, WWBOTA, HEMA, Parks 'n' Peaks, ZLOTA, WOTA, LLOTA, WWTOTA, Tiles on the Air, the UK Packet Repeater Network, and any site based on the xOTA software by nischu.
Spothole can retrieve alerts from: NG3K, POTA, SOTA, WWFF, Parks 'n' Peaks, WOTA and BOTA. It also fetches contest dates from WA7BNM Contest Calendar and RSGB contest calendars.
Spothole can retrieve solar and propagation condition data from HamQSL, the NOAA Space Weather Prediction Center, the Lowell GIRO Data Center and prop.kc2g.com by KC2G.
Spothole can also perform lookups for callsign data on behalf of the user from QRZ.com and HamQTH.
Note that the server owner has not necessarily enabled all these data sources. In particular it is common to disable RBN, to avoid the server being swamped with FT8 traffic, and to disable APRS-IS and UK Packet Net so that the server only displays stations where there is likely to be an operator physically present for a QSO.

As of the time of writing in August 2026, I think Spothole captures most radio programmes that have a defined, downloadable reference list, and almost certainly those that have a spotting/alerting API. If you know of one I've missed, please let me know!
