Roster Announcement 8-18-26

Mission: Turn anonymous DX-cluster observations into a concise local view that helps operators choose promising bands and directions without retaining individual callsigns. As historical evidence grows, the project will develop carefully labeled outlooks that become more useful across times of day and seasons.

When Both is selected, propagation evidence from N7OD and the WaveLog API is analyzed together while each source remains identifiable.

How to use the report

• Choose a view, provider, and observation window under View Options.
• Read the overview first, then open a continent and one of its rated regions for path details.
• Improving, Degrading, and Steady compare the selected window with the equal window immediately before it.
• Band Activity evaluates every supported band independently. Good, Marginal, and Poor describe the strength of current reported evidence.
• Best Outbound and Best Inbound identify the bands with the strongest current directional evidence. Frequency is not a ranking factor.
• No Current Evidence means no qualifying reports were received; it does not prove that a band is closed.

How the outlook will mature

The current display reports observed evidence; it does not yet predict how long conditions will last. Forecast wording will be introduced only after measured backtesting.

• About 30 days — Experimental Outlook: early time-of-day and directional patterns.
• About 60 days — Developing Outlook: improved guidance for frequently observed bands and regions.
• About 90 days — Provisionally Validated Outlook: limited to well-sampled region, band, and time combinations under conditions similar to the season observed.
• Six to twelve months: comparison across changing seasons. Summer observations should not be treated as a complete guide to generally stronger winter conditions.
• One year and beyond: a full annual baseline with increasingly useful seasonal comparisons. Sparse paths may require longer.

Scoring and confidence methods are versioned so later refinements do not silently rewrite what older reports meant.
