Click the heading. Within each PERIOD and never across them: the slots
are what this panel is — what was on the air in one fifteen-second
window — and a list sorted end to end would mix three minutes of decodes
into one column of numbers with no way to tell which window any of them
came from.
One click sorts the way that column is worth reading — strongest signal,
lowest frequency, furthest DX, A to Z, most wanted — the second reverses
it, and the third gives arrival order back. Arrival order stays the
default and stays one click away, because it mirrors the decoder's own
window line for line, which is what makes the two screens comparable at a
glance.
Status ranks by the cluster's own order, so the two views rank the same
things the same way, with the markers that are orthogonal to the entity —
a new county on a worked country — sorted above the plain duplicates.
A station that never sent a grid cannot be placed, and an unresolved
country is not a name: both sort to the end whichever way the column
goes, rather than pretending to a distance of zero and heading the list
under "nearest first".
The rest between two series was two minutes — four overs on FT8, by
which time the DX has worked four other callers and half the time has
gone. It is now counted in the station's OWN overs and is one by default:
seven calls, one over listened through, and it goes again if the station
is still there. The deadline lands mid-cycle on purpose, so "sit out one
over" means one over rather than depending on a millisecond of clock
skew.
A period the target was DECODED in is never counted as a miss. A period
is judged more than once — decodes arrive in a burst and stragglers
follow — and a later judgement holds a partial view of it, not evidence
of absence: D2ACE answered in the very period the counter then read as a
miss.
The readout moved out of the Auto button and beside it. "Auto D2ACE 1/7
·1/3" read as one number, and the control changed width every period.
The callsign is now the biggest thing on the row, the calls and the
missed periods each carry a label, the miss count appears only once there
is one, and a station being waited for gets its own amber chip.
Six faults from an evening on 60 m, all in the same family: the engine
judging a station by what the log wants from it and forgetting what is
already under way.
- An exchange was abandoned mid-QSO. The reply lands in the same period
the ladder is re-read, and that period was judged before the reply was
taken into account, so a better-ranked caller took the slot from a
station that had just come back to us. The answer is settled first now,
and our own report counts as being inside the exchange too — which also
protects a QSO the operator started by hand.
- A station just picked started with misses against it. Its transmit slot
was unknown until a second decode, and with the parity unknown every
period counted, including the one spent transmitting to it.
- The freed slot after "it is working somebody else" was thrown away: the
period's decodes are in hand, so the next station is picked from them
rather than fifteen seconds later. Never mid-over.
- Auto-call is never armed from a stored setting — not at launch, not on
a profile switch. It is the one feature that puts the station on the
air by itself and OpsLog starts with Windows.
- It says what it is waiting for: a wanted station in a QSO with somebody
else now shows beside the Auto button instead of looking idle.
- Switching profile left the previous logbook's verdicts on screen. The
worked-index, chase-new and the frontend's cached verdicts are dropped
when the logbook changes.
FT decodes: distance column, a message addressed to you set whole in
green (the station you are calling keeps a tint — most of what it sends
goes to other people), badge order L / Wkd / WL, list cleared when the
RIG changes band.
Rotor: new world-map compass from EC1KD's design, with the Ultrabeam boom
and second lobe restored and the compact form preserved; the classic dial
is kept and Settings → Rotator chooses between them. Stop no longer
flickers on a rotor standing still — movement was inferred from a degree,
less than the jitter a controller reports at rest.
Decodes:
- one click SELECTS, two transmit. A single click handed the decode
straight to WSJT-X as a reply, so brushing a row while reading the
band started calling a station.
- the list empties for a receiver that changes band, and a receiver
column appears when more than one is feeding one merged list.
- the period clock turns red while transmitting: it is the one thing on
the screen that moves, so it is where the eye already is.
- a WL badge, after the LoTW "L" — one letter, always in the same
place, so the column does not shift from row to row.
- the auto-call switch, its target and its count, and the chase list:
naming the station you are waiting for is done while watching the
band, not in a settings tree.
Themes: DXHunter's slate with its own blue, and the same slate with
OpsLog's orange. Counted across its sources rather than guessed from
one panel — blue is 132 uses to violet's 25, and the violet is the PSK
Reporter panel alone.
Watchlist: drawn as DXHunter draws it — the callsign in the interface
font rather than monospaced, which is the difference that shows with
the two windows side by side.
FT Map: arcs no longer run off the side of the map. The map shows one
world, and a path crossing the antimeridian was drawn past 180° into
the blank space beside it — from VK that is most of them.
Cluster: "superfox", "fox/hound" and "F/H" in a comment are read as
FT8. They are WSJT-X's DXpedition transmit modes, and the comment fell
through to the band plan and came out DATA — which then decided the
band+mode verdict.
A decoder is named by what it IS: Nexus sends its packets as "Tempo",
the engine inside it, and OpsLog showed a program nobody has heard of.
A decoding application that loses its CAT link keeps announcing the last
dial frequency it knew, and every decode after that carries a stale
band. Nothing downstream can tell: the entity verdicts, the band filter
and the FT map all believe it. Seen for real — MSHV kept saying 80 m,
and Korea read as a NEW BAND because on 80 m it would have been.
Said, not decided. Taking the rig's band instead would be wrong for
anyone decoding a second receiver on another band, and a warning costs
that setup nothing but a line to read past. Shown only while CAT is
actually connected: an empty band means there is nothing to compare
with, never that the rig is on no band. Opens 0.27.9.
The FT map drew a strip of dead space along the bottom after a zoom.
Leaflet measures its container ONCE, at creation — which for this panel
is the instant the tab is selected, before the flex layout has settled —
and then asks for tiles to fit that stale size for ever. A ResizeObserver
hands it the real size, plus one pass after the first paint for the
layout that settles without ever firing a resize.
And the decode list's continent chips are the seven, fixed. Building
them from the feed meant a row that reshuffled itself every period — a
chip appeared when the first Asian station decoded and moved everything
sideways under the pointer — and it could not say what the filter was
capable of until something had been heard.
Chase POTA, US counties, prefixes and grids were written for the cluster
and stayed there, so an operator who does not chase parks still met NEW
POTA in the FT decode list and in Chase new: the same badge withdrawn on
one screen and shouting on the next. The setting is about what is hunted.
One helper answers the question for every panel, keyed by both the status
field names and the shorter category names so a single call serves badges
and filter chips alike. Chase new also stops CATEGORISING a row by a
marker that is switched off, which had left rows listed with no visible
reason for being there. A new US state has no switch of its own, so it is
always allowed.
Dimming the filled chip to a transparent background left its light
foreground text on nothing — an invisible badge in the row. Unconfirmed now
renders in the category's own hue, dashed border and text, like the extras
beside it.
The frontend caches statuses and only asks about unknown keys, so flipping
the chase mode left half the screen judged under the old rules until a
restart — which read as the mode not working. The backend now broadcasts an
invalidation and the panels re-ask as rows repaint. The entity badges also
say their name with a question mark, dashed, when the need is only a missing
QSL — the 50% opacity was invisible on a filled chip.
The unconf label was hard-coded to GRID? for every category — a prefix
worked-but-unconfirmed showed as a second grid badge beside the real one,
which read as impossible. Each badge now says its own name plus a question
mark. And the global Chase block moves above the Chase POTA/SOTA/grid
checkboxes, where its operator expected the master switch.
The gap between worked and confirmed becomes visible everywhere. A Chase
setting on the DX Cluster page picks the mode; in new-plus-unconfirmed the
verdicts for DXCC/band/mode/slot, prefix, county and state are judged against
CONFIRMED-only ledgers built from the operator's chosen sources (LoTW, card,
eQSL, QRZ.com — HRDLog has no confirmation field in ADIF to offer), and a
need that exists only because a QSL never arrived is flagged Unconf: the
cluster and decode badges render it dimmed, the convention the grid hunt
introduced. The grid's own Chase selector folds into the global one; its
square-matching scope stays where it was, being grid-specific. One snapshot
key change rebuilds the cache when any of it flips.
The WAS gap made visible: a worked-states set joins the cluster status cache
(distinct states over the three US entities), the status entries carry a
NewState flag wherever the state resolves (log county first, ULS licence
second), and the decode panel gains the badge in its status column plus the
filter chip alongside NEW/BAND/MODE/GRID. Colour from the shared marker
palette, so the cluster can adopt it later without a second hue.
Between the locator and the country, per its operator: the two-letter badge
anchors the eye and the spelled-out name answers it — 'SD' alone is a quiz
for a European. The status-cell badge from the first pass moves here.
Plain text, not a badge — it is a fact, not an action — placed first so a
WAS chaser can scan the column edge. Shown whenever the status cache knows
the state (log county data or the licence address).
The panel now mirrors the decoder's own window line for line — the operator
compares the two side by side, and the SNR sort scrambled that
correspondence. The report is still right there in its column.
A station new on this band AND in this mode is one status, 'new-band-mode',
and the badge table has an entry for neither half. The lookup returned
nothing, so those rows showed only their grid or prefix badge — and with
NEW/BAND/MODE selected, a row whose visible badges were LOC and PFX read
as the filter letting through things nobody asked for. It was not: the
row belonged there and the panel failed to say why.
catsOf has always split that status into its two categories for filtering.
The badges now do the same on screen.
Panadapter spots are now worth reading. The comment carries the spotter, the
entity and the status in DXHunter's own shape — "CQ up 2 [F4BPO] [Franz Josef
Land] [New Slot]" — which needed two things nothing documents: SmartSDR splits
its command line on SPACES, so the words ran together until every space became
non-breaking; and it truncates past ~60 characters, so the cluster's own words
are trimmed first and the three brackets always survive. RBN column padding is
collapsed on the way in, or a preserved run of spaces opened a gap wide enough
to push the rest off screen.
"Already worked" means the CALLSIGN is in the log, not the entity: saying it of
a station never contacted was simply wrong. Each status can also be kept off the
panadapter entirely, and the WSJT-X decode spots obey the same switches — the
palette governs the panadapter, not one of the two things that feed it.
And the radio is no longer hammered: a spot whose frequency, colour and comment
are unchanged is not removed and redrawn. A busy skimmer feed re-spots the same
station every few seconds; one two-minute session sent 2128 adds, 88 of them for
a single callsign, and the display did not move a pixel for any of them.
CI-V, from an IC-7850 that kept killing JTDX: a reply the rig sent to another
controller on the same bus is no longer taken for ours, and a set_ptt, set_freq
or set_mode whose acknowledgement goes missing is verified by reading the rig
back instead of being reported as a failure. WSJT-X and JTDX answer a failed
command with a Rig Control Error and drop the link mid-over — 98 keyings, 6 lost
acknowledgements, 2 dropped connections in one session. The check waits 700 ms,
not the poll's 150: the rig has just failed to answer twice because it was
retuning, and a short probe would fail for the same reason.
Auto-call is withdrawn — it duplicated DXHunter, which already answers decodes,
and two programs deciding that from one shack key over each other. The library
is kept whole and dormant; a guard in App.tsx makes sure a stored preference
cannot key a transmitter whose switch no longer exists.
Also:
- the log rotates while running, not only at startup: the CI-V trace left on
wrote 416 MB and nothing would have stopped it before the disk did. Closing
it now releases the crash file too — the runtime keeps its own duplicate.
- the interface zoom announces itself, with a badge, a click back to 100% and
a View menu; Ctrl+wheel and Ctrl+0 always worked and nothing said so.
- no more elastic bounce, and no swipe-to-navigate out of the app.
- Edit QSO: your own TX power and the contacted station's extended locator
were saved and written back with no box to set them.
- FT decodes: continents are a multiple choice; a compound MSHV message that
answers two stations in one line is recognised as addressed to you.
Compared side by side, DXHunter's decode list is plainly easier to read,
and three things account for the gap.
The Call column repeated what the message already said. Every FT8 line
opens with the callsigns — "CQ A93MO LL56", "PG5FRL JH3CUL PM74" — so a
column in front of it printed the same token twice and pushed the line
everyone actually reads to the middle of the row. It is gone; the message
is the identity, and the tokens worth finding are picked out inside it:
green for CQ and for our own call when someone answers, red for the station
we are calling. The grid went with it, being the message's last token.
Time is on every row now, compact, no separators. A decode belongs to a
period and the section heading names it — but once a slot runs past a
screenful the heading is somewhere above, and an instant you cannot read
where the decode is is not an instant you have.
Band and mode became their own columns, band as a chip, and the status
flags moved into one column at the right edge with LoTW and a "worked"
marker beside them. Rows are tighter: 13 px for the message and the report,
11 px for the figures, 10 px for the badges, and the column rules run
through the lot.
A countdown for the T/R slot, against the UTC clock — a bar, the seconds
left, and the mode. Slots are anchored to UTC rather than to when OpsLog
started, so it is computed from the wall clock alone and keeps running when
the band is dead and there is nothing to group. The last fifth of a slot
turns amber: that is when a decode is imminent and an operator deciding
whether to answer has run out of time to think.
Which exposed a real fault in the grouping. Status reports the T/R period
as a whole number of seconds, so FT4 arrives as 7 or 8 depending on which
way the sender rounded, and the code floored to whole seconds on top of
that — two FT4 periods landed in one heading and others were split down the
middle. The slot length now comes from the MODE, which knows the exact
figure and the whole halving family (FT8 15, FT4 7.5, FT2 3.75), with the
sender's number only as a fallback; and the arithmetic is in milliseconds.
Sub-second slots get a decimal in their heading, or two FT4 periods inside
one second would print the same time twice.
Two rows now stand out from the band behind them, because they are not
about the band at all but about the QSO in progress:
- the station being called is red, taken from the transmit state, so it
can be found in a slot holding thirty others;
- anyone ANSWERING is green and labelled, which outranks everything else
on the screen. A reply is a decoded line that opens with our own
callsign — bracketed too, since a non-standard call comes back
compressed.
Clicking a decode now ANSWERS it. It sends WSJT-X/MSHV a Reply message
(type 4), which is the same thing as double-clicking the line in their own
Band Activity window: the application looks the decode up, sets its
transmit frequency to the caller's and starts the exchange.
It deliberately does not tune the radio, which is what it did before and
why nothing happened. On FT8 the whole band sits inside one passband, so
moving the dial changes nothing about who gets answered - the decision
belongs to the decoding application, and the Reply is the only way to hand
it over. Tuning would also just fight it for the VFO. The entry is still
filled so the QSO can be logged here.
The reply is routed by PROGRAM ID, not by listener: two receivers can share
one multicast group, and answering a station heard on the 6 m instance by
talking to the 20 m one would start a call on the wrong band. It goes to
the address that instance's packets actually arrive from - a multicast
listener must answer the sender, never the group. WSJT-X matches the reply
against its own decode list, so the payload replays the decode field for
field: time, snr, delta time, audio offset, mode and message text.
Two columns added, DT and Freq - the audio offset inside the passband, not
the RF frequency, which is the same for every station in the list and says
nothing. Past about two seconds DT takes a warning tint: that station is
drifting out of the window.
The transmit strip. "You cannot see what you are sending, or who you are
calling" - two separate faults. The message was only ever threaded into its
period, and in FT8 you transmit in the slots you are NOT receiving in, so
its period had no decodes and the whole line was dropped; a transmit slot
now creates its period. And the state is a strip of its own at the top,
because it is the one thing on the screen that is about the operator rather
than the band. It is fed by every Status rather than only by one carrying
transmit text, so it can still name the station being called on MSHV and
older JTDX builds, which stop before tx_message in the Status payload.
"New only" became per-category badges, in the colours and the vocabulary of
the Chase New panel. None lit shows the whole band - this is a decode log
first, and a panel that opened by hiding most of the traffic would be lying
about what is on the air.
Three things from reading it on a real screen.
Column rules. The grid alone was not enough to follow a line across: cells
now carry a right border and the row stretches, so the rules run unbroken
from the header to the bottom of the list. That is what turns rows of text
into a table.
Left-aligned. The previous pass centred the grid inside a maximum width,
which on a wide screen opened a dead margin down the left before the first
callsign - trading the hole in the middle for a bigger one at the edge. Now
it fills the width and the slack lands in the message column, which is the
one that can use it and the one bounded by rules on both sides, so it reads
as a cell rather than a gap.
"CQ CQ PE1NAO JO32" - a green CQ badge in front of a message whose own
first word is CQ. The badge is gone; the word already in the line is picked
out instead, which scans the same and stutters not at all.
First pass on the panel from operating feedback.
Columns are a grid template shared by the header row and every data row, so
the two cannot drift and the eye has a rail to follow. It is capped at
1500 px and centred: free-flowing, a 2500 px window put the country a foot
from the callsign it belonged to and left a hole in the middle of every
line.
"New" gets a COLUMN. It was only a coloured edge before, which says
something is special without saying what — and every one of these is a
reason to break off what you are doing and call. The entity verdict is a
solid badge, the orthogonal ones (park, grid, prefix, county) are outlined
in the colours markerColour already gives the cluster list and the band
map, so a new park is the same green in all three. Applied inline because
those are categorical --chart-* custom properties, which the theme does not
expose as Tailwind colour utilities: written as border-chart-7 the badge
would simply have had no colour.
Band and mode selectors now appear only when the feed actually carries more
than one of each. One MSHV is one band and one mode, so for most operators
they were furniture; they show up the day a second instance puts a second
band on the link, which is the only day they mean anything. Same rule for
continent, and a receiver count when more than one instance is feeding.
Added a LoTW-only filter, and raised the type throughout (call and message
to 14 px, secondary to 12 px, badges to 11 px) with more room per row.
The decode payload now carries the sending application's own id. It tells
two receivers apart on one multicast group — and it is the address a
WSJT-X Reply message would have to go back to, so it is carried now rather
than requiring another trip through the parser later.
Every FTx decode WSJT-X, JTDX or MSHV puts on the wire, grouped by T/R
period. Optional and closable, from Tools -> FT decodes; its open state is
remembered, because an operator running digital modes leaves it open for
the session rather than consulting and closing it.
The period is the point, and what separates this from the cluster list.
FT8 is a sequence of fifteen-second slots and a band is read by watching
them go by: who called CQ this slot, who answered, what I was sending while
they did. A flat list sorted by time loses exactly that, so the list is
grouped one section per period, newest first, with the operator's own
transmission shown inside the slot it went out in.
Three fields had to be carried up from the wire to make it possible:
- the decode's OWN timestamp, which the parser read and threw away. It is
what assigns a slot: a period's decodes arrive in one burst a second or
two after it closes, so arrival time piles a whole period into the next
one. Rebuilt to UTC from milliseconds-since-midnight, with the
day-boundary case handled - a decode stamped 23:59:58 arriving at
00:00:01 would otherwise be dated a day ahead and sit at the top of the
list for the rest of the session.
- the decoded line itself. The exchange is what says where a station is in
a QSO, and no set of extracted fields reads like "R-09" does.
- tx_message and transmitting from Status, which nothing parsed before.
Recorded once per message rather than on every Status, which repeats it
about once a second for the whole over.
Also picked up on the way: is_new, low_confidence, off_air, the operator's
own call and grid, and the T/R period itself - better authority on slot
length than the mode name, which says nothing about a custom period. The
Status tail is read defensively: those fields were appended over successive
schema versions and JTDX and MSHV each stop at their own point, so a short
packet is normal and keeps whatever parsed.
Status flags come from ClusterSpotStatuses, the resolver the cluster list
and band map already use, filling the same cache. One verdict per call:
"new band" in this panel and plain worked in the cluster two seconds later
would be worse than no flag at all. Clicking a call goes through the same
handler as a cluster spot, so answering a station is one gesture whether it
came off telnet or off the receiver.
Filters: CQ only, new-anything only, band, mode, continent, an SNR floor
and a free search. The band, mode and continent choices are built from what
is actually on the feed - offering 160 m to a station whose receivers are
all on 6 m is noise.
Decodes are held in the frontend and pruned to a rolling half hour: they
are a live view, not data, nothing outside the panel reads them, and a
night of FT8 on 20 m would otherwise grow a list no filter can rescue.
Arrivals are staged on a 300 ms timer so a period landing as fifty packets
costs one status lookup and one render.
