ApplyNetworkSettings disposed the station link without clearing it, so
ApplyStationLinkSettings disposed it a second time and threw. Only the
second function touches the link now, and StationLink.Dispose can be
called twice.
Contacts from the network are queued and applied together on the window
thread. Each one used to rescore the whole log and redraw the log window,
which kept the window thread busy for minutes during a resync.

A QTC row holds the serial of the contact it reports, which the station
being reported sent, not us. The serial pool was filled from every row in
the log, so reporting a station that sent us 1800 pushed our own next serial
to 1801, and reopening the log read it back from the rows again.
The pool now takes the sent number of contacts alone, when a contact is
logged, when one arrives from another station of the entry, and when the
numbers are seeded from the log at startup. N1MM leaves both QTC kinds out
of the same query, in QSONrsByBand.
The test opens a real log file, sends a series, closes the store and opens
it again, so the series numbering and the contacts already reported are
checked across a restart as well.

The button started the numbers again at one. N1MM's manual says it "sets
serial numbers on all computers to the highest value in any of the logs,
plus 1", and its own handler re-reads the highest number per band out of
the log, so a mixed network came apart at exactly the point the button is
meant to repair: the N1MM stations counted on from the highest number and
this one started at one, sending numbers that had already gone out.
ContestSession.RestartNumbers fills the pool from the log, which is where
the reset now lands. SerialNumbersFrom is gone with it, and so is the pool
this station sent afterwards: N1MM sends none, because each station works
the same number out of its own copy of the log.

Each station worked out its next number as the highest in its log plus one,
so two operators typing at the same moment both sent the same number and
one of the two contacts was wrong in the sponsor's log.
SerialNumberPool holds the highest number taken per band, which is N1MM's
QSONumbers array. A number is taken at the first character of the callsign,
as N1MM takes it, and ReserveNr tells the other stations before the contact
is worked. A number at or below one this station has used is answered with
the whole pool, N1MM's QSONRS, and the station that is behind counts on from
there. The pool also goes out when a contest is opened and when the numbers
are started again.
Contest.NumbersByBand says whether the numbers run per band or as one
sequence for the station. CQ WPX runs one per band for a multi-two and a
multi-multi; every other contest here runs one sequence. The band index in
the message is N1MM's, so the array lines up with theirs.

Seven tabs now, in N1MM's order, and the messages behind them.
**Options** holds what there is something behind: Log QSOs at all Stations,
which decides whether the contacts the others log are kept here; the
message trace, moved off the Messages tab where N1MM does not keep it; and
Run1/Run2, which used to be guessed from the radio number and is now the
operator's choice, sent in every `STATUS` and every `XMIT`. The transmit
interlocks stay out: this program does not block a transmitter, and a
station that claimed it did would be waited on for nothing.
**Call Stack Targets.** A callsign heard at one station and handed to the
position that will work it — `STACKANOTHERCALL` with the call alone,
`STACKCALL` with the contact behind it. The target is picked from the tab
or from the station list, and what arrives goes on the call stack of the
radio the operator is on, sorted by whether it is a multiplier here.
**The master** is the station the entry follows for cluster spots and the
time. `MASTER` names it to everybody, so the column agrees everywhere.
**The clock.** `TIME` carries a station's clock and Force Time Sync sends
it. N1MM sets the clock from it when it is running as an administrator and
says how far out it is when it is not; this program always does the second,
because setting the clock needs root and a contest logger has no business
asking for it. Anything over two seconds is called out.
**Serial numbers.** Reset Serial Numbers at all Stations sends
`RESETQSONRS` and every station starts again at one. The contacts already
logged keep the numbers they were sent with.
**What the entry agrees on** is now checked rather than assumed:
| What | How |
|---|---|
| the contest | `CONTESTNAME` as soon as a connection opens, and again in every `CHECKSUM` |
| the country file | its issue date — the publisher's `=VER20260826` — rides in `STATUS` |
| the computer name | longer than N1MM's fifteen characters is named at startup; a second computer answering to this one's name is named when its beacon arrives |
| the station number | two stations on the same number are named when the second says so |
`CountryFile` reads its issue date, which nothing had asked it for before.
Left for later: the master relaying its cluster spots, and the shared
serial-number pool where stations claim numbers in advance.

A station that was away — a laptop that lost the network, one that was
switched off — comes back missing whatever the others logged while it was
gone. N1MM fills that in by walking the log an hour at a time, and this is
that walk, on the same messages:
| Message | What it says |
|---|---|
| `CHECKSUM` | here is what I hold for your contacts in this hour, and the contest and callsign I am logging |
| `DELETEQS` | drop your copies of my contacts in that hour, I am sending them again |
| `RESYNCQSO` | one of those contacts |
| `CONFIRMED` | here is what the hour hashes to at my end — which also asks for the next hour |
Each station is the authority on the contacts it made, so an hour that
disagrees is replaced rather than merged. The answer to one block asks for
the next, and the walk ends when the block starts after the end of the
period. The Resynchronize tab counts the hours that agreed, the hours that
were sent again and the hours that still disagreed, which are N1MM's
columns.
**`LogChecksum`** is N1MM's: a CRC32 over the `DXLOG` columns of the block,
ordered by time and then callsign, leaving out what each station works out
for itself — points, the three multiplier flags, the country prefix, the
continent, the WPX prefix and `IsOriginal`. Two stations may disagree about
those and still hold the same log. A checksum that disagrees for any other
reason costs one block of traffic, which is what a resync is for.
**The link still holds no log.** It asks one through `ContactLog` for the
contacts of a computer in a block of time, and `SessionContactLog` answers
on the window thread, because that is where the log is touched.
**Every contact logged here now carries the computer that made it.** N1MM
stamps `NetBiosName` and `NetworkedCompNr` on every row and this program
did not, so its own contacts belonged to no station and a resync could not
ask for them.
**Rescore** writes the points and multiplier flags of a period back to the
database. The log in memory scores itself whenever it changes; the stored
rows do not, and N1MM reads them rather than working them out. A contact
that arrives from another station after the one that took a multiplier
leaves those columns behind. A station can also ask the others to rescore
when its resync finishes, which is the flag on the end of `CHECKSUM`.

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.

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.

AppSession.TakeFromNetwork wrote the contact to the store and then called
OpenContest to see it, which built a new ContestSession, read the whole log
back and built new entry positions. Anything the operator was typing at either
radio went with them, and the entry boxes were rebuilt under the other
operator's hands. It also ran on the socket thread, so it was changing the log
while the windows were reading it.
ContestSession now applies the three messages itself: AddFromNetwork,
ReplaceFromNetwork and DeleteFromNetwork write the store, change the log in
place and raise Changed. None of them raises Logged, Edited or Deleted, so
nothing goes back out to the other stations. Points and multipliers are still
worked out here from the rules rather than trusted.
A contact that arrives goes in where its timestamp says it belongs, through
the new ContestLog.Insert, and the log is scored again: of two stations that
worked the same multiplier, the one that worked it first keeps it, however
late the message turns up. Add would have appended it at the end and given the
multiplier to the wrong contact.
The socket thread now hands the update to the thread the windows run on, which
is where every other change to the log is made.
The matching rule moved with the code, so ContestSession answers what a
message from N1MM refers to: the contact id, then the call and time it had
before the edit.
Still not tested against a second station. Two of these cannot run on one host
to try it, because they share one UDP port.

The menu tree comes from N1MM's EntryWindow.Designer.cs: File, Edit, View,
Tools, Config, Window, with the items under the names N1MM gives them. The
window list moved out of View into Window; the call history file moved from
Config into File > Import. Ctrl+W, Ctrl+L and Ctrl+M now work, so the keys
printed in the menu are real. Two commands that had no menu item before:
the CW and SSB function key definitions, and the QTC setup area.
The rest of the Edit menu:
- Ctrl+N asks for a note and puts it in the comment of the contact in the
boxes, or of the last logged contact when nothing is typed.
- Edit Current Contact opens the Edit Contact form over what is typed but
not logged. Update hands the values back to the entry boxes.
- Ctrl+Q and Ctrl+A load a logged contact into the boxes and paint them
pale yellow. Enter writes the change back, Esc puts back what was being
typed, and stepping forward past the newest contact leaves quick edit.
- Ctrl+U raises the received serial, or a numeric exchange box when the
contest has no serial.
- Ctrl+F shows the call being typed in the log window, then the next
contact with that call.
RadioPosition is now OperatingPosition: it is the operator at one radio,
not a place on a band.
Looked at under Xvfb on a 3775-contact log: quick edit back and forward,
Esc, the note dialog, find, and Edit Current Contact putting a zone back
into the entry boxes.

N1MM's format, so a file published for a contest is read as it is: # comments,
!!Order!! naming the columns of the lines after it, semicolons in preference to
commas so user text can hold a comma, and a default column order for a file
that names none. The directives that change what is stored are acted on;
!!Order!! can appear again part way through, because these files are usually
several files stuck together.
Leaving the callsign box fills what the file knows into the exchange boxes that
are still empty. A box with something in it is left alone: what the station
actually sends beats what somebody published months ago. The zone comes from
the CqZone or the ITUZone column depending on which the contest asks for, and a
file with no Sect falls back to State.
The check window's two missing columns are in. History lists matching calls
from the file. Exchange is not about callsigns at all: it offers the values the
exchange box with the cursor in it can hold, which is what N1MM's exchange pane
does — it searches the contest's list of valid exchanges, not the log.
CheckCandidate.Call is now Text, because an exchange value is not a call.
The section-validating directives are read and passed over rather than acted
on. Acting on them means holding N1MM's section lists and its rules about
retired sections, and getting that wrong throws away good data.
Running it caught what the unit tests could not: the exchange was filled and
scored but the boxes on screen still looked empty, because nothing resynced
them.

LoggingSession mixed two things: the contest, which one station has one of,
and what the operator is typing, which belongs to a radio. It is now
ContestSession and RadioPosition. Two positions share one log, one score and
one run of serial numbers, so a station worked on radio 1 is a dupe on radio 2.
Frequency, mode, split, what is typed and whether you are running belong to
each radio on its own.
A second radio opens a second entry window. It has no menu of its own: it is
another view of the same contest, not another program. Only the window for
radio 1 opens the database and the connections.
Ctrl+Tab moves the operator to the other radio and the keyboard follows.
Ctrl+Shift+Tab puts both radios in the headphones.
OtrspBox speaks OTRSP to an SO2R box over a serial port: TX1/TX2 for the key,
RX1/RX2 and RX1S for the headphones, AUXnnn for an output line. It follows the
active radio, and every message points the box at this radio before keying, so
a message cannot go out of the radio the operator has just left. A command that
would change nothing is not sent, because the box works relays; N1MM does the
same. The box takes a Stream, so what it sends is tested without a serial port.
Still missing: alternating CQ, and voice keying on the second radio.
Looked at under Xvfb with two fake radios, one of them split: both windows up,
radio 1 showing 14008.00 into 14020.0, radio 2 on 14030.00, Ctrl+Tab moving the
keyboard between them.
