The square ring made a marker at 45° sit further from the centre than one at north — a dial is read by angle, so the ring it is read against is now the same distance away all the way round. The antenna is drawn as a sector that fades outwards, which is the shape of the thing it stands for; where the mouse would send it appears in the same shape in orange, and its azimuth in place of the current heading while you aim. Green for where the antenna is, orange for where it would go, yellow for what was ordered — the second lobe of a bidirectional Ultrabeam and the dashed boom are unchanged. Design from EC1KD again.",

Three delays were stacked between the antenna finishing and the operator being allowed to call — the antenna polled every two seconds, the transmit gag held for three after the command whatever the antenna said, and the screen refreshed every three. Both the Ultrabeam and the SteppIR are now polled four times a second WHILE IT MOVES (and left at two seconds when it is still, where nothing changes), the gag only bridges the command itself, and the widget follows at half a second. The SteppIR also reports a commanded move at once, as the Ultrabeam already did: it says nothing until its own poll comes round, so the shortened gag would otherwise have released the transmitter in the middle of a move.",

The transmit gag already started there; the screen did not, so the two disagreed by a second or more — and on a follow there was no warning at all until a poll landed.",

The message that authorises the stream is sent during the login, before the audio socket exists — so the rig was told to send audio to a port nothing was bound to, got a port-unreachable back, and only resumed when its own retry timer came round. It is sent once more as soon as the port is listening.",
+      "Icom over the network: when CI-V goes quiet while the experimental RX audio stream is still delivering, the log now says so and names the switch to try. The two share the rig’s session, and the shape in the field is exactly that — hundreds of audio packets arriving, not one CI-V reply, the watchdog tearing the session down, and the whole thing starting again. The silence report also lists the last eight CI-V commands sent: a rig that answers at connect and then never again has usually been sent something it does not like, and a count of unanswered commands never said which one.",
+      "Icom over the network: a rig left in standby no longer sits in a dial-and-drop loop. The clock that bounds “the control link answers but no CI-V comes back” belongs to a session and was never cleared when a new one opened, so every fresh session started already past its grace — torn down at once, redialled twenty seconds later, and torn down again for as long as the radio was asleep. Silent since connect is now read as what it is: a rig in standby, with the session kept so it can be woken.",

A device unplugged, renamed by Windows or unable to run at 16 kHz failed silently while everything upstream reported success — the stream up, the packets arriving, the monitor started — which is the whole of “I turned the sound on and nothing comes out”.

Line breaks inside a value are now joined with a comma, which is how an address reads on one line anyway. The files were always valid (ADIF counts bytes); they were unreadable.",

The check added for services with no credentials demanded a Club Log API key, which nobody has ever set — OpsLog carries its own application key — so an operator whose live upload had worked for months was turned away when sending QSOs by hand.

+// It is the other way round from internal/pskr. That watcher asks what is
+// happening AROUND HERE — reports collected near the operator, whoever sent
+// them — and it is the right shape for finding a band opening or a new entity.
+// This one starts from a callsign the operator wants to work and gathers the
+// evidence about that path, in both directions:
+//
+//   - did the DX decode MY call, and how long ago
+//   - who NEAR ME did the DX decode (the path is open at my end)
+//   - who near the DX decoded ME (the path is open at his end, even when he
+//     uploads nothing himself)
+//   - how many stations he is decoding right now (the pileup I am up against)
+//   - where in his receive passband those decodes land, so a caller can pick a
+//     slot he is not already covered on
+//
+// Nothing here is persisted and nothing is inferred from a QSO: it is a sliding
+// window of PSK Reporter reports, and when the window empties the answer goes
+// back to "not known", which is the honest answer.
+//
+// The window is FIVE minutes. An FT8 cycle is fifteen seconds, so that is
+// twenty chances for a path to show itself — short enough that "he decoded you"
+// still means now, long enough that one missed cycle does not erase it.
