An operator waited over a minute and the button never appeared; opening
Settings and pressing Cancel made it appear at once. That is the whole
diagnosis — Cancel was the only thing that re-read the option.
GetChaseNew returned the cached atomic, which exists for the MQTT goroutine
and is false until startup has read the setting. The UI asked while the
database was still opening, was told "off", believed it, and never asked
again. It now reads the setting, like the grid-chasing binding beside it.
The frontend asks again at the two moments this class of race resolves: when
GetStartupStatus returns, and when the first logbook load succeeds — the seam
that already re-reads the connection label for exactly this reason, with a
comment saying so.
The open/closed state was already remembered per machine; it is now in
PORTABLE_KEYS with the other widget toggles, so it travels with data/ like the
rotor and amplifier panels rather than being the one that does not.
Three cuts, all of them removing things nobody could act on.
The frequency column is gone. Clicking the row tunes the rig to it, so the
number was there to be read and never used. It is still carried on the spot —
the click is what needs it — and it is in the row's tooltip. The country takes
the space.
Modes are limited to FT8, FT4, FT2, PSK31 and RTTY. WSPR is the one worth
spelling out: it is a beacon, nobody answers a WSPR transmission, so a "new
entity on WSPR" is a path report and not a station to work — and on a quiet
band it would have been most of the list.
Bands are limited to the operator's own list. PSK Reporter carries every band
its receivers listen on, and a 13 cm decode is not an opportunity for a station
with no 13 cm.
Both tests run before the status lookup and both read a cached map: they throw
away most of the feed, so nothing downstream pays for it. The band list is
re-read when the lists are saved, so ticking a band in Settings applies to the
next decode rather than the next restart — which would have looked like the
filter not working.
PSK Reporter tells you what is actually being decoded in your region, which
is a larger set than what somebody chose to spot: nobody spots the FT8 caller
running ten watts from a rare square.
Almost all of it existed. The MQTT payload already carries frequency, mode,
transmitter and both grids; the watcher already drops any report collected
further than NearKm from the operator, which is exactly the question worth
asking — the station is being heard HERE, not in Japan; and with grid chasing
on the subscription is already every band, filtered at the broker by receiver
square, measured at 0.2 to 1.2 messages a second. This reads messages that
were arriving and being discarded.
"New" is not decided here. Every spot goes through ClusterSpotStatuses, the
same function the DX cluster grid uses and the same cached index, so the two
panels cannot drift apart the way the county columns did. Cost per message is
map lookups behind an option cached in an atomic, because the MQTT goroutine
must never wait on the settings store.
The option is its own, not nested under grid chasing: chasing squares and
chasing entities are different wants, and the feed now has three consumers,
any one of which brings it up and none of which cuts the others loose when it
goes down.
The panel says "digital modes only" in its footer. An empty list has to mean
"nothing new on FT8/FT4/JS8 near you", not "the band is dead" — it will never
show a new entity on CW.
