# What is not finished, and what has not been tested

Two separate lists. A feature can be finished and untested, or half-built and
exercised every day. Written 2026-08-27, updated 2026-08-31.

## Never run against the real thing

Everything below is written from a published protocol or from N1MM's source and
tested against a fake that speaks the same protocol. A fake agrees with whatever
the person who wrote it believed, so these are the places where a wrong belief
is still sitting there undiscovered.

| What | Tested against | What has never happened |
|---|---|---|
| `RigctldRadio` | a stand-in for `rigctld` over a real socket | no real `rigctld`, no real radio. The extended answer format, the `+` prefix and the split commands are from the documented protocol. If the format is wrong, nothing works rather than something being subtly off — check this first. |
| `OtrspBox` | a `MemoryStream`, checking the bytes | no real SO2R box. Command forms are from N1MM's `N1MMPort.cs`. |
| `ClusterClient` | a node fake over a real socket, sending the telnet negotiation, the login prompt and spot lines | no live cluster node. Which nodes send bare CR, and which send option negotiation, is guessed from N1MM's code. |
| `StationNetwork` | the message format, round-tripped | no second station, and no N1MM on the same network. |
| `CwDaemonSender` | the UDP messages, and a fake daemon that answers the `<ESC>h` reply request | no `cwdaemon`, no radio keyed. |
| `MmttyEngine` and the Wine bridge | MMTTY 1.70 under Wine 10, started and stopped through `XMMT.ocx` | no sound card, so nothing has been decoded or transmitted and no `rx` or `tx` line has come from a real signal. No FSK through EXTFSK, no PTT on a serial port, and 2Tone has never been run. `docs/digital-bridge.md` |
| `WinkeyerSender` | the status-byte reader, on its own | no test of the serial side, and no WinKeyer. The host-mode open sequence is from the WinKeyer datasheet; the status bits are from N1MM's `Winkey.cs`. |

The Cabrillo output has not been put in front of a contest sponsor's robot.

## Half-built

**The digital window: what N1MM has and this does not.** The window is here —
receive pane, coloured callsigns, grab list, call stacking, twenty-four macro
buttons, the engine controls — and the function keys, ESM and the QTC window
send through the engine on a digital mode. Left out: the waterfall, the spectrum
and the XY scope, which the engine reports and nothing draws; more than one
receive pane, which is MMVARI's multi-channel decoding rather than MMTTY's;
sending a text file; and N1MM's Send All, which keys a whole QTC series at once.
The other interfaces N1MM offers — fldigi, MMVARI, the hardware TNCs — are not
here either, though `DigitalEngine` is the place to add them.

**Voice keying.** `MessageSender` was written to cover a voice keyer playing a
recording, and nothing implements it. No DVK support either, so the second radio
of an SO2R station cannot call CQ by voice. Alternating CQ therefore works on CW
only, though nothing in it is CW-specific: a voice keyer that reports when the
recording has finished would drive it as it stands.

**The QTC window transmits on CW only.** The header, the lines, the QRV, the TU
and the again messages go out through the keyer, with N1MM's messages and
N1MM's defaults. Nothing goes out on SSB or RTTY: N1MM plays four recordings on
SSB — QRV, Agn, Cfm and TU — and sends RTTY from its digital window, and this
program has neither a voice keyer nor a digital window. N1MM's Send All, which
keys a whole series at once, belongs to that RTTY window and is not here
either.

**Cut numbers are not sent.** N1MM can key a serial number as letters — `N` for
9, `T` for 0 — and offers several styles. Nothing here does, in a QTC line or in
any other message.

**Two WAE numbers do not agree with N1MM, both from 2020 and 2021 logs.** The
disagreements are the country file of the day, not the rules: 4U1A counted as
`4U1V` then and as `OE` in today's `wl_cty.dat`, `KP2BH` counted as `KP2` then
and is listed as a US call now, and China was not split by call area yet. The
2022 to 2025 logs agree to the contact.

**Telnet window: what N1MM has and this does not.** Left out: the special-calls
list, and saving received spots to a database — N1MM keeps those spots in its
admin database, which is not the log file the two programs share, so there is
nothing to be compatible with and nothing asks to read them back. The band plan
tab is not repeated either, because Config ▸ Sub bands already edits the same
numbers.

The node list is downloaded from the public NG3K page rather than from N1MM's
own web service, which asks the operator to opt in to data collection and is
N1MM's to run. A page that changes shape would stop the download working; the
reading only needs `telnet://` links in a table, and the old list stays in place
when a download brings back something unreadable.

**Not every action macro is acted on.** The text macros and the action macros
that this program can carry out are listed in the README. What is read and
passed over: the `{CAT…}` and radio-hex families, the audio and rotator macros,
`{STEREOON}` and `{STEREOOFF}`, `{CONDJUMP}`,
`{QSYCQ}`, `{FORCELOG}`, `{SwapContests}`, the digital TNC macros (`{ENTER}`,
`{ESC}`, `{CTRL-A}`…), and the wav-directory macros, which wait on voice keying.
A message holding any of them still sends the right characters.

The CW keyer macros are not read either: `<` and `>` for speed, `~` for a half
space, and the prosign characters `]`, `[`, `+` and `=`. They belong to the
keyer rather than to the expander — cwdaemon and a WinKeyer each have their own
way of saying them — and they go out as the characters they are.

**The busted-spot check is one character wide.** N1MM offers two. Every call one
character away from the spotted one is looked up in the callsign database, which
is a few hundred lookups per spot; two characters away is a few hundred thousand,
which is too much work per spot for the little it would add.

**Two BARTG contests share one set of rules.** N1MM has a class each for the
March HF RTTY contest, `BARTGSRTTY`, and the September sprint, `BARTGRTTYS`.
This program has one contest, named `BARTGRTTYS`, holding the March rules — the
ones the station's log needs — and both of N1MM's names open a log with it. A
sprint log would be scored by the wrong rules, and a log started here writes
`BARTGRTTYS` into the contest name, which N1MM would read as the sprint.

**Digital modes.** A contact can be logged as RTTY or another digital mode, and
the contest rules score it, but there is no digital window: no decoding, no
transmitting, no interface to fldigi, MMTTY or similar.

**Contest coverage.** Twenty-five families are built in, plus whatever `.udc` files
are in the user-defined folder. N1MM ships well over a hundred. Opening a log
from a contest that is in neither place fails with the contest name, which is
the right answer but it is still a wall.

Most of what is missing does not need code. A contest whose exchange is a
report and one value, scored by band, mode, continent or country, and counted
by country, zone, section or prefix, is a `.udc` file, and the file published
for N1MM is read as it is. Code is for the ones `.udc` has no words for: WAE
needs QTC traffic, IOTA needs island references as multipliers, and CQ WW RTTY
needed a third multiplier and its own points table because it shares a name
with the CW and SSB running of the contest.

`.udc` settings that are still passed over. `MultiplierBands` and
`QsoErrorString`, which are about the windows rather than the score.
`GenericPrintString`, which is the layout of a printed log rather than a
Cabrillo one.

`MultWindowType` is read as far as the score goes: it names the list a section
multiplier is checked against. Four of N1MM's lists are held here — the ARRL
sections, the US states, the Canadian provinces and the OK/OM districts — and a
file naming any of the hundred-odd others falls back to counting any exchange
that is not all digits.

`CabrilloString` and `CabrilloVersion` are read: a contest whose sponsor asks
for its own columns gets them, in N1MM's shape — the operator's callsign in the
first 13 columns, then every column padded to the width the file gives with one
space after it, and a value longer than its column cut rather than pushed. The
numbered `CabrilloFormat` layouts 2, 3, 4 and 5 — the NAQP, NA Sprint,
Sweepstakes and section-and-serial lines — are read as well, in N1MM's columns.
The exchange those layouts split into columns is built from the boxes the file
defines, in the order it defines them; N1MM builds it from the section box
alone, which writes only half of a two-box exchange. Layout 6, the ARRL RTTY
Roundup line, is not read, and a file asking for it gets the default line; no
published `.udc` file asks for it, because the Roundup has a contest class of
its own. `CabrilloFormat = 0` means the sponsor takes no Cabrillo log at all,
and nothing here stops the operator writing one.

N1MM's `.udc` format has no way to say that the exchange itself differs by the
other station's country. OK/OM DX is written in code for that reason — it asks
a county from OK and OM stations and a serial number from everyone else — and
`Contest.SkipsField` steps over the box that does not apply. REF, ARRL 10M, the
Ukrainian DX contest and the Russian DX RTTY contest ask their exchange the same
way, and are written in code for the same reason.

Every contest in the station's own logs can now be opened, and its 78 contest
instances score contact for contact as N1MM did apart from the cases below.

What still differs, and why:

- **The EU DX Contest** is written from N1MM's own class. The station's logs
  were made with the `EU_DXC.udc` file instead, which scores a contact inside
  your own country 1 point where the class scores 2, and counts a district code
  once in the contest where the class counts it once per band.
- **Field Day Region 1**: every contact in that log holds 1 point and no
  multiplier, which is not what N1MM's own class works out, so the log looks
  like it was never scored. The rules here follow the class: 5 points for a
  portable station, 2 for one in Region 1 at home and 3 from outside it.
- **SA 10 and OK/OM DX on SSB** are not written in code at all: both are
  published as `.udc` files, and with those files in the user-defined contests
  folder the station's logs score to the contact. N1MM's OK/OM DX class is the CW running only and says so; the SSB
  running has different rules and its own pair of files, one for each side of
  the contest.
- **Two OK/OM DX contacts** whose district code was stored with a trailing
  space. N1MM checks the code against its list without trimming it, finds
  nothing and counts no multiplier; the code is trimmed here and counts. Both
  contacts are the same station in the 2026 log.

## Known rough edges

**The band plan covers 160M to 2M only.** 60M and everything above 2M get no
CW, digital or phone shading on the bandmap, because N1MM's own numbers for
those bands contradict themselves — its CW top for 1.25M is below its phone
start, and its 70CM CW top is above the band. Config ▸ Sub bands cannot add a
band that has no default.

**Available mults and Qs is only as good as the bandmap.** It lists what is
spotted, so a multiplier nobody has spotted is not there. N1MM's window also
shows the mults a contest has and nobody has worked, which needs a list of every
multiplier the contest counts. Only the section and state lists are held here,
so the zone and country lists would have to come from the country file first.

**Two entry windows and one keyer.** The SO2R box is told which radio to key
before each message, but nothing stops both radios sending at once if the
operator asks them to.
