Here is an example of how WSPR spots are stored in the central DB (11 billion historic spots) and what information they contain. You can filter by any of these criteria. Everybody can access the DB. FT8 ? Central DB? Historic data? TX powr? Drift? spotQ?

It's surprising how many people have never heard of WSPR and don't know what it is...

The window for easy DX is slowly closing. π
We had a phenomenal run β SC25 blew past all predictions. But the descent has started, and the next solar minimum is coming. Efficient low-band antennas and a proper station setup become more important than ever. 73

Be careful when looking at MUF Maps. While the guessing process is pretty good in areas that are closer to the measurement stations, the uncertainty (error) is much higher in areas that are far away from any measurements

We had 3 fantastic HF Prop years in SC25. Now, say goodbye to top DX condx on 20-10m and hope for a great SC26. 73

π 10m band DX down 31% year-over-year. SC25 is descending.
πΉ Spots/TX: 2,132 β 1,480 (βΌ31%)
πΉ SFI: 188 β 135 (βΌ28%)
πΉ Ap: 10.4 β 10.1 (flat)
Nearly identical geomagnetic conditions β the decline is pure solar flux. The F2 MUF is losing its grip on 28 MHz long-haul paths.
