       "Band-opening detection now has the data it needs. Switching on \"Watch for band openings\" (Settings › DX Cluster) subscribes to the PSK Reporter feed — every station on the air reporting what it decodes, rather than the handful of VHF spots a cluster carries — and adds the two RBN nodes if they are missing. Pick the bands to watch: 12, 10, 6, 4 and 2 m. An MQTT chip in the status bar, beside the rig and amplifier, shows the feed is alive.",
       "Opening detection now covers 12 and 10 m, not just 6, 4 and 2 m. The feed was already subscribed to them while the detector still threw them away, so a busy 10 m could never be announced. An opening under way now shows as a blinking badge in the status bar, beside the clock, and stays there until the band goes quiet — the toast that announced it was gone in seconds, while an opening lasts hours.",
       "Test connection now actually tests. Club Log checked that the three fields were not empty and reported success without contacting anyone, so a wrong password looked exactly like a right one; it now signs in for real, through the read-only endpoint so a test can never add a record. LoTW reports its two credentials separately: TQSL signs uploads and never uses the website password, so a wrong one used to break nothing until the day confirmations were downloaded.",
-      "Opening detection finds an opening through the everyday noise. It used to require every station heard to fit inside one 90° sector, which suits a sporadic-E cloud and nothing else: with 10 and 12 m open the reports come from all round the compass, so the busier the band, the less likely it was to be announced. It now looks for the busiest sector instead. The direction reported was also wrong whenever a sector crossed north — an opening to the NE was announced as SW, the exact opposite."

+      "Openings are now about YOUR region. A PSK Reporter message says \"X was heard BY Y\", and only the receiver being near you shows that signals are arriving here — a station heard in Japan proves a path that is not yours. Reports are kept when the receiving station is within 300 km, which borrows the ears of a whole region instead of waiting for a decode at your own antenna. 12 m has been dropped from the watched bands: at this point in the cycle it is open often enough that announcing it is a notification rather than news."

Activer « Surveiller les ouvertures de bande » (Paramètres › Cluster DX) souscrit au flux PSK Reporter — toutes les stations en l air qui rapportent ce qu elles décodent, au lieu des quelques spots VHF que porte un cluster — et ajoute les deux nœuds RBN s ils manquent.
