A spotted activation is counted as a unique callsign and park reference in the spot stream. These summaries do not verify the 10 or more contacts required for an official POTA activation.
Frequently Asked Questions
How are spots counted?
A "spot" is a report of an activator being heard on the air. We collect this data every minute and aggregate it hourly. The total spots count represents the sum of all spot reports in the selected time range.
How are unique activators counted?
Unique activators are counted by extracting distinct callsigns from all spots in the time range. If the same operator is spotted multiple times across different parks, bands, or modes, they still count as one unique activator.
How are "spotted activations" tracked?
A spotted activation is a unique combination of callsign + park reference in the spot data.
Important: These are spotted activations based on spot reports only. We cannot verify whether the activator made the 10+ contacts required for an official POTA activation.
What do the mode categories mean?
- CW - Morse code
- SSB - Voice modes (SSB, AM, FM, LSB, USB)
- Digital - FT8, FT4, RTTY, PSK31, JS8, etc.
How does this work?
Raw spot data is pulled in once a minute via a Cloudflare Worker and stored as NDJSON files into Cloudflare R2. Periodic rollups make it easy for the browser to query.
