Three pieces on top of the link:
**The network status window**, on the entry window's Window menu. A row
per station, this computer included the way N1MM shows it: number,
address, operator, band, mode, run, transmit, pass frequency, the last
message type, how long ago it arrived, the counts each way and the echo
round trip. A station that broadcast the wrong version is named under the
table in red — that is the one fault where everything looks connected
and nothing arrives. The box at the bottom sends a line of chat, and
Echo asks every station whether it is there.
**Where this station is** goes out once a second when it has changed.
The frequency, the mode and run have a dozen places they can change from
— the radio moving, a band button, a QSY typed into the callsign box —
so it is read and compared rather than announced from each of them.
**The ten-minute rule.** `BandChangeRules` already counted changes and
the stay on a band, and the entry window already showed the countdown,
but only a user-defined contest carried a rule, so every built-in
contest allowed anything. `ForCategory` gives a multi-operator entry
with one or two transmitters a ten-minute stay, which is N1MM's fallback
in `ContestInstance.BandChangeTimerDuration` for every contest that does
not name its own. Its per-contest table is a few hundred cases in a
decompiled hash switch and is not repeated.
Config ▸ Edit Networked-Computer Names now covers both networks: the
12060 broadcast to other programs and the 12070 link, with the station
number, the port, the version to claim and stations named by address for
a network where a broadcast does not reach.

SOBandChangeTimerDuration and MOBandChangeTimerDuration say how long a
station has to stay on a band it has just moved to. Both were read by
nothing: N1MM counts them down in its info window, which this program
does not have.
The countdown now stands in the entry window's status bar, next to the
contacts and multipliers, ticking with the clock that is already there.
BandChangeRules.StayLeft works it out from the log, starting the stay at
the minute after the contact that changed band, which is where N1MM
starts it.
Which contests show it is decided at runtime rather than by a list: the
rules come from the contest for the entry's own category, so a file that
asks for no stay, or asks for one only of single-op entries while the
station is entered multi-op, shows nothing at all.

Four settings were read by nothing.
MultipleSessions = 0000/30 runs the contest in half-hour sessions from
00:00 UTC. The session is part of the dupe key, so a station worked in
an earlier one may be worked again, and ResetMultsEverySession and
ResetSNEverySession start the multipliers and the serial numbers over.
DupeQSOMinutesAgo is the other way back to a station: after so many
minutes rather than in the next session. The log holds the time of the
last contact per dupe key instead of only the key, and the setting's
IgnoreBand and ThisMode decide the scope, because a file that uses it
turns DupeType off.
MinimumOffTime drives the time on and time off the score summary now
shows under the score, and beside them are the band changes made against
the allowance for a contest that limits them. N1MM's countdown for the
minutes you have to stay on a new band needs its info window and is not
here.
UdcFile.Flag now takes 1 and 0 as well as True and False, which is what
these settings are written as and what N1MM reads.

MultSqlString = CallHist counts every station the call history file
lists, once per callsign, which is how N1MM dedups it. The file reaches
the scoring code through ContestLog.History, and a QsoContext now
carries it; without a file loaded nothing counts.
BonusPoints2 = +50, calls.txt reads the callsigns from the support-files
folder and adds 50 to the contact, *2 doubles it and a plain 50 scores
50 instead. The folder comes from the registry, which the app passes
when it reads the .udc files. N1MM's other form, where the file is
grids.txt and the bonus is looked up by grid square, is not read.

MultWindowType names the list N1MM validates a received section against,
and every exchange that was not all digits counted as a multiplier here.
Four of N1MM's lists are held now -- the ARRL sections, the US states,
the Canadian provinces and the 165 OK/OM districts, which came out of
N1MM's own exe -- and a file naming one of them counts only the values
on it. A file naming any of the hundred-odd others keeps the old rule.
The 2023 OK/OM DX log now scores contact for contact as N1MM did. Two
contacts in the 2026 log still differ: the district code is stored with
a trailing space, which N1MM matches against its list untrimmed, so it
counts no multiplier where this counts one.

I wrote SA 10 and OK/OM DX SSB in code after two failed attempts at the
download. The download works — the page posts a nonce with the form — and the
files say I got both contests wrong.
SA 10 is deleted from the code. Its file scores the station's log to the
contact, where the code had the wrong Cabrillo name and counted its multipliers
once in the contest rather than once per mode.
OK/OM DX now covers the CW running only, which is what N1MM's class is for and
what N1MM's own documentation says: the SSB running has different rules and a
pair of .udc files, one for each side. The CW rules go back to the class, so
Czechia and Slovakia are one side of the contest again. With the SSB files in
place both of the station's SSB logs score to the contact.
Reading those files turned up four things in the .udc reader: a file whose
extension is upper case was passed over, `Country` was not read as a
multiplier source, `OtherCountry` was not a points condition, and a section
multiplier counted the serial numbers the other side of a contest sends.
All Asian stays in code — N1MM has a class for it after all — with the Cabrillo
name and the band table it uses.

REF, the Ukrainian DX contest, the BARTG Sprint, ARRL 10M, Russian DX RTTY,
RDAC, YO DX HF, Oceania DX, IARU Region 1 Field Day, SARTG RTTY, All Asian and
SA 10. Every contest name in the log now opens, and every one of these but
Field Day scores its log contact for contact as N1MM did.
Most are written from N1MM's own class and checked against the log. Three
things the log settled that the class does not say plainly: ARRL 10M counts its
multipliers once per mode rather than once, the BARTG Sprint counts a continent
once in the contest while its countries and call areas count per band, and RDAC
counts nothing but the districts and scores nothing for a station that sends
none.
All Asian and SA 10 have no class in N1MM, which logs them from a .udc file, so
those two are written from the published rules and the log. docs/unfinished.md
lists what is still not settled.

Four more of the contests in the station's log. IOTA, CQ 160 and Mexico RTTY
score every contact in it exactly as N1MM did.
IOTA pays 15 points for a station that sends an island reference and 2 for one
that does not, and counts each reference once per band and mode. CQ 160 is one
band, so its states and countries count once each. Mexico RTTY and CQ 160 both
take a state from one side of the contest and a serial or a zone from the
other, in the columns N1MM keeps them in.
The EU DX Contest is written from N1MM's class, including its list of what
counts as Europe: the European Union, its outermost regions and its overseas
territories, and nothing else. The station's own logs were made with the .udc
file, which scores and counts two things differently; docs/unfinished.md says
which.

Both are in the station's log and neither could be opened. The rules are
written from the published ones and checked by replaying the log.
YOTA scores a contact by the age the other operator sends: 13 points down to 10
for anyone 25 or under, whatever the continent, and 1 point or 3 for everyone
else. Every age worked on a band is a multiplier. The 2024, 2025 and 2026 logs
come out to the contact.
OK/OM DX is the first contest whose exchange differs by the other station's
country: a county from OK and OM stations, a serial number from everyone else,
in the two columns N1MM keeps them in, and `SkipsField` walks the entry window
past the box that does not apply. Points depend on which side the operator is
on, and Czechia and Slovakia count as the two countries they are. The 2023 log
comes out to the contact.
The Cabrillo exchange now gets the entry, because YOTA sends an age that only
the contest setup knows.
Two differences are left in the log, both from the .udc files the operator
used: their YOTA file only lists ages 7 to 25, so a younger operator scored as
an adult, and one OK/OM log was made with the file for stations outside OK and
OM while signing an OM call.

The three differences left after replaying the log were ours on purpose. A log
has to score the same in both programs, so they now follow N1MM:
- ARRL DX and CQ WW RTTY count the 14 Canadian areas N1MM lists as `48SDC14P`,
which keeps Newfoundland apart from Labrador. A station sending the postal
code is counted as the area the contest names.
- A maritime mobile is scored from the call it signs. CQ WW says it counts for
the zone alone; N1MM gives it the country, and so do we.
- A callsign the country file cannot place counts as a multiplier with an empty
value, so every unplaceable call worked on a band shares one multiplier.
29 of the 37 contest instances in the log now agree with N1MM on every contact
and on the totals. What is left is the country file of the day and rows whose
cached points N1MM never worked out again after a call was corrected.

Two pieces of work on the scoring engine.
The .udc reader now takes N1MM's published scoring vocabulary: the full
PointsPerContact condition set, the PointsMultBy family, PowerMult, BonusPoints,
the multiplier sources and the settings that say which stations bring a
multiplier in. MultMult is a weight rather than a switch, as in N1MM's
ComputeScore. The entry categories and the sent exchange reach the rules in a
new ContestEntry, so a contest can score by the power category it is entered in
or by what this station sends.
Then every contest in a real N1MM log was scored again from these rules and
compared with the points and multiplier flags N1MM wrote. That found five bugs:
ARRL DX and IARU read the exchange from the wrong column, a stored " " was read
as a value rather than as empty, CQ WW RTTY's own Canadian area names were not
counted, a maritime mobile scored nothing, and a contact in a mode the contest
does not run scored as if it were in the contest.
docs/n1mm-interop.md has the check and what still differs.

WAE is two contests in one. The QSOs are scored like any other, except that a
multiplier is worth four on 80 metres, three on 40 and two on the high bands, so
Multiplier grew a weight and ScoreTally sums weights rather than counting.
Europe works the rest of the world and the rest of the world works Europe; on
RTTY that rule is dropped and everybody works everybody.
The other half is QTC traffic: one station reads back contacts it has already
made, ten to a series, and every line is a point for both stations. Those lines
live in the log as rows of their own, exactly where N1MM puts them — Exchange1
says SQTC or RQTC, the reported contact's time, call and number go in the sent
report, received report and sent number columns, and the series in misc text.
So a log written by either program opens in the other with its traffic intact.
A QTC row is not a worked station: Contest.IsContact says so, and ContestLog
keeps such rows out of the dupe index and the multiplier index while still
counting their points. Cabrillo writes them as QTC: records.
Checked against eight real WAE logs rather than against my own reading of the
rules. Points agree with N1MM on all eight, to the contact. Weighted
multipliers agree on the six logs from 2022 on; the two older ones differ only
where the country file has since changed its mind, and in one place on purpose:
N1MM counts a callsign it cannot place as a multiplier with an empty value.
That comparison turned up two bugs of ours. A KG4 call is Guantanamo Bay only
when it is three or five characters long — KG4NE is, KG4IGC is an ordinary US
call — and the country file cannot say so, so every program that reads it
carries the rule. And Callsign is a record holding a list of modifiers, so the
generated equality compared that list by reference and two parses of one call
came out different.
Entering QTCs while operating is not there yet; the window is next.

CQWWRTTY resolved to the built-in CQ WW with the mode set to digital, and then
scored it as though it were the CW running: a contact inside your own country
worth nothing, two multiplier types, and CQ-WW-SSB in the Cabrillo header. Every
one of those is wrong for RTTY, and wrong quietly, which is the worst way.
RTTY is a different contest wearing the same name. Every contact scores — 1
inside your own country, 2 on your own continent, 3 off it. The exchange carries
the state or province after the zone, and that is a third multiplier per band.
A station outside the US and Canada sends DX there, so the box is not required
and DX brings no multiplier.
The state box being optional is deliberate: most of the log is DX stations, and
holding up an entry for a box that will hold DX costs more than it is worth.

The box names in EntryWindowInfo are N1MM's LogItem.LogItemNameType members.
We read four of them under names that are not in that enum, so a file naming
its section box SectionText got no section box at all, and a zone or a power
box was dropped whatever it was called.
SectionText, CQZoneText and PowerText are now read. SectText stays as well: it
is not one of N1MM's names but files in the wild use it.

Three things stopped it.
A contest is keyed by ContestNR, not by ContestID. ContestID is only the
ContestInstance table's primary key; DXLOG.ContestNR refers to ContestNR, which
is what N1MM's SQLWhereString matches on. The two agree in a fresh log and
drift apart in one that has been used for a while, so we were reading one
contest's header with another contest's contacts. In a real log of 56284
contacts, joining on ContestID disagreed with the contact's own ContestName
52029 times; joining on ContestNR disagreed 109 times.
N1MM names a contest per mode: CQWWCW, CQWWSSB, CQWWRTTY, never plain CQWW.
Our contests now use those names, and N1mmContestNames turns one back into a
contest and a mode when a log is opened. The name carries the mode, so it beats
the ModeCategory column. Plain CQWW still opens, because older versions wrote
it that way.
The log columns were sized by counting characters, which was too narrow for the
headers: those are drawn in the theme's font, not the grid's monospace. The
grid sizes them now, with the character count as a floor so a column of short
values does not collapse.
Bandmap spots now age from when they arrived rather than from the time written
in them. A node with a wrong clock, or one replaying its backlog on connect,
emptied the bandmap as fast as it filled it.
Checked by opening a real 56284-contact N1MM log under Xvfb and reading the
contest and contacts back.

ARRL DX, IARU HF, Sweepstakes, RTTY Roundup, NAQP and general logging join
CQ WW and CQ WPX. The Cabrillo QSO line is now built column by column by the
contest, because Sweepstakes puts the callsign after the serial number where
everyone else puts it first.
User-defined contests read the subset of N1MM's .udc settings that covers the
exchange, the dupe rule, points and up to three multipliers.

Frequencies, bands, modes, callsigns, grid squares and the country file live in
Nonemm.Core. Nonemm.Contests holds the scoring engine and CQ WW and CQ WPX.
Nonemm.Storage writes N1MM's DXLOG schema, and Nonemm.Formats writes Cabrillo
3.0 and reads and writes ADIF.
