The WSJT Decode List Window

The WSJT Decode List provides a bi-directional interface between the Band Activity Panel in WSJT-X or JTDX and N1MM+’s contest log.

Key Features

  • QSO initiation, auto-sequencing, and logging from within the WSJT-X or JTDX program
  • Contact logging in both the WSJT-X or JTDX log and the N1MM+ contest database
  • Callsign prioritization (normal, mult, double mult) based on contest contacts in the N1MM+ log
  • Dupe callsign warnings based on contest rules (bands, modes) and existing contacts in the N1MM+ log
  • Instructions for using WSJT-X or JTDX with N1MM+ can also be found in a file called “N1MMWSJTInstructions.pdf” in the Additional Support Files file gallery on the N1MM+ web site

Configuring the WSJT Decode List Window

Within N1MM+

There are several places in the Configurer that need to be set up for WSJT-X interoperation with N1MM+. These include the Mode Control page and the WSJT/JTDX Setup page in the Configurer window (note: in versions 1.0.7645 and earlier, the settings that are now on the WSJT/JTDX page were on the Broadcast Data page and the Digital Modes page). You also need to ensure that the Contest Setup is configured to include Digital modes (otherwise digital mode contacts will not be given points credit).

To enable logging from WSJT-X to N1MM+, configure per the following settings on the Configurer’s >WSJT/JTDX Setup page.

To enable logging from JTDX to N1MM+, in addition to configuring the UDP port as for WSJT-X above, you also need to configure the TCP port for JTDX logging to use port 52001 and check the Enable box in the “JTDX / Others TCP Settings” area.

In order to allow N1MM+ to call up the WSJT-X or JTDX program, you must also enter the location of the WSJT-X or JTDX program. Rather than attempting to type in the path to the WSJT-X or JTDX program manually, use the Select button. Clicking on this button opens an Open File dialog window, in which you can navigate to the location of the executable program (wsjtx.exe or jtdx.exe) and select it to fill in the box automatically.

The bottom section on this page implements the Auto Load feature for the Decode List window. If the Enable check box is checked, calling up the WSJT-X or JTDX program from the Window > Load WSJT/JTDX menu item will also automatically open the Decode List window as well.

Starting with version 1.0.7860, N1MM+ supports running two copies of WSJT-X or JTDX in SO2R (but not in SO2V). There are boxes on the WSJT/JTDX Setup page in the Configurer for entering the port number(s) and program location for the second radio. The UDP/TCP port number(s) for the second radio are different from the UDP/TCP port number(s) for the first radio, and will need to be changed in the settings for the Radio #2 (EW2) instance of the WSJT-X or JTDX program. You can use the same copy of the WSJT-X or JTDX program from both radios, even though they will use different settings; each one will store its settings in a different location.

When you are using WSJT-X or JTDX, the radio should be in the same mode as it uses for PSK. Still in the Configurer, on the >Mode Control page, on the right-hand side under Mode sent to radio, you need to set the mode in the PSK row correctly for your radio. On some radios, this might be PSK, or perhaps AFSK-R, or if your radio does not have a separate Data mode for digital modes, it might be USB. Consult the Digital Mode Mapping table in the Supported Radios chapter of this manual for the mapping between mode names on the radio and the mode names that appear in the pull-down list on the Mode Control page of the Configurer.

Make sure the correct contest mode is selected
Note that for duplicate and multiplier information to be recorded and transferred correctly, the correct contest must be selected in N1MM+, and the program must be in Digital logging mode (the easiest way to do this is to type FT8 or FT4 into the call sign box in the Entry window and press Enter).

Note that the contest Mode category in the contest setup dialog window must contain DIGITAL. If the contest mode is RTTY, contacts in other modes (including FT8 and FT4) will be assigned zero points. After changing RTTY to DIGITAL or SSB+CW to SSB+CW+DIGITAL in the contest setup window to correct this, you will need to use the Tools > Rescore Current Contest menu item to rescore any FT8 or FT4 QSOs that had not originally been assigned the correct score.


First, if you have made custom changes to the WSJT-X or JTDX settings and wish to retain those same settings when running together with N1MM+, you might want to follow the procedure described in the colored text box at the end of this section before starting to configure the special instance of the program that is used with N1MM+.

If you will be running WSJT-X or JTDX from within N1MM+, you must make the WSJT-X (JTDX) configuration changes described below from WSJT-X (JTDX) after it has been called from within N1MM+, not after it has been started stand-alone. The stand-alone configuration settings do not apply when WSJT-X/JTDX is run from within N1MM+.

After starting WSJT-X or JTDX from N1MM+, configure per the following settings on the >File >Settings page in the UDP Server panel under the Reporting tab:

In the “Logging” area, the upper two check boxes control how logging in WSJT-X is controlled. Most users will likely want one or the other checked – i.e. either have the program prompt the user to log the QSO at the end of the QSO sequence, or else do the logging automatically. If neither one is checked, you must remember to click on the “Log QSO” button at the end of every QSO, and it is very easy to forget to do this, in which case the contact will not be logged.

In the “UDP Server” area, the “Accept UDP requests” check box must be checked in order for the WSJT Decode List window to work. It enables the passing of duplicate/multiplier information from N1MM+ to WSJT-X or JTDX, as well as allowing WSJT-X/JTDX to use N1MM+ for rig control if it is called up from the N1MM+ Window menu. For SO1R or Radio #1 in SO2R (EW1), the default port number of 2237 is correct; for Radio #2 in SO2R (EW2), change the UDP server port number to 2239.

In JTDX, there is another TCP port that needs to be set up in the “External logbook connection” area. For SO1R or for the first radio in SO2R, the default TCP port is 52001. For the second radio in SO2R, this would be changed to correspond with the setting in the N1MM+ Configurer’s WSJT/JTDX Setup tab (suggested 52006).

In WSJT-X, do not check the Enable check box in the “Secondary UDP Server” (WSJT-X version 2.1.0) or “N1MM Logger+ Broadcasts” (WSJT-X version 2.0.1) area. This is not used when WSJT-X is run from inside N1MM+.

In order to enable N1MM+ to call up WSJT-X or JTDX from the Window > Load WSJT/JTDX menu item, under the Radio tab in WSJT-X or JTDX change the rig control method to “DX Lab Suite Commander”.:

For SO2R, in the setup for the Radio #2 (EW2) copy of WSJT-X or JTDX, immediately below the Rig: box, you will need to change the Network Server port to . You do not need to enter anything in this box for SO1R or for Radio #1 in SO2R.

Note that you do not actually run DXLab Suite’s Commander program; N1MM+ uses the same method as Commander to communicate with WSJT-X or JTDX, so the same Rig setting can be used in WSJT-X/JTDX. Choose your PTT Method, radio’s Mode and Split Operation method depending on your radio.

If you choose CAT as the PTT method, what that really does is tell WSJT-X or JTDX that N1MM+ will be handling PTT control. You must have a method of PTT control configured in the N1MM+ Configurer for this to work. You can check the “PTT via Radio Command Digital Mode” check box in the setup window for the radio control port in the Configurer, or configure a serial port in the Configurer for PTT control, or if you are using a Winkeyer, connect a PTT cable from the Winkeyer’s PTT output to the rig’s PTT input jack. Any of these will work with the CAT PTT method selected in WSJT-X/JTDX when it is run from inside N1MM+. If you are using a SignaLink to perform the PTT function, or if you are using the rig’s own VOX function, select VOX as the PTT method in WSJT-X/JTDX.

The Mode section in the WSJT-X and JTDX setup is used to tell the program which mode to put the radio in while operating in JT modes. If your radio has a special mode for sound-card data modes that you want to use, make sure to select the Data/Pkt setting in the setup here, and you must also ensure that the N1MM+ Mode Control is set properly for your radio as described in the previous section. For older radios that do not have a data mode, you might need to choose either USB or None in this section.

The Split Operation pane in the WSJT-X and JTDX setup controls how WSJT-X/JTDX handles audio frequencies outside the “ideal” 1500-2000 Hz range. If either Rig or Fake It is chosen, then if an audio frequency outside that range is chosen, whenever WSJT-X/JTDX commands N1MM+ to put the rig into transmit, it will also request that N1MM+ QSY the radio by a multiple of 500 Hz so as to put the audio frequency back into the “ideal” range. This avoids problems with audio harmonics or with reduced audio gain in other parts of the bandpass. If Rig is chosen, the QSY will be done using the rig’s split operation capability; if Fake It is chosen, the main VFO will be QSYed every time you switch between transmit and receive. With some rigs, there may be an objectionable delay or other problems when switching to transmit with the Rig setting chosen; if this happens to you, try using the Fake It setting instead.

There is another setting under the General tab in the WSJT-X/JTDX Settings window that is not strictly speaking necessary, but that will probably make operating easier, and that is the “Double-click on call sets Tx enable” check box, which we recommend you check. You might also want to check some of the other options, depending on your operating preferences.

WSJT-X/JTDX Configuration when run from inside N1MM+

If you are running WSJT-X or JTDX from inside N1MM+, the first time you open it you may notice that all of the WSJT-X/JTDX settings have been restored to default values – for example, your call sign and grid square may not be entered under the General tab. If you want to avoid having to manually re-enter all of your preferred settings (other than the ones described above), there is an optional way to transfer them over from your stand-alone setup to the setup within N1MM+.

In WSJT-X, use the File > Open log directory menu item to open a Windows File Explorer window open to the directory where WSJT-X stores its settings. If you do this from the stand-alone version of WSJT-X, this will be C:\Users\[yourusername]\Appdata\Local\WSJT-X. If you do it from WSJT-X after it has been called up from within N1MM+, the directory will be C:\Users\[yourusername]\Appdata\Local\WSJT-X – ForEW1 (or ForEW2 for the copy of WSJT-X called up for the second radio in SO2R). You can navigate to the …\WSJT-X directory, find the file called WSJT-X.ini, copy it and paste the copy into the …\WSJT-X – ForEW1 directory. Then rename the copy to WSJT-X – ForEW1.ini (after deleting or renaming any existing file with that file name). If you had already made the configuration setting changes described earlier on this page, you will have to make them again. From now on the two configurations will be independent; changes made to one will not affect the other.

In JTDX, the same procedure applies, except that the path names and file names will say JTDX instead of WSJT-X.

Configuration for a Specific Contest (WSJT-X only)

WSJT DecodeList SettingsAdvanced2
  • For most contests, click the “Special operating activity” checkbox, the radio button adjacent to the contest that you intend to operate, and in some cases the Exchange box at the right, as follows:
    • For the ARRL RTTY Roundup – SW/VE stations should insert their two character state/province abbreviation. DX stations should use the expression “DX”, which will enable sequential serial number exchanges.
    • For the ARRL Field Day – Enter the exchange information describing your station configuration (e.g. 1D EMA – see ARRL instructions).
    • For the WW Digi contest at the end of August, use the NA VHF Contest setting (during pre-contest testing, you can leave the “Special operating activity” check box unchecked and use normal non-contest mode; the WW Digi contest exchange is compatible with the normal non-contest mode in WSJT-X).

Launching WSJT Decode List

If you are running WSJT-X or JTDX from within N1MM+, use the N1MM+ >Window > Load WSJT/JTDX menu item (last one in the list) to start WSJT-X/JTDX, as configured under the WSJT/JTDX Setup tab in the Configurer. In addition to the WSJT-X or JTDX window(s), there will also be a small N1MM+ window that opens:

If you have checked the Auto Load check box on the WSJT/JTDX Setup page, the Decode List window will open automatically at the same time as the WSJT-X or JTDX program. If you have not checked this option (or if you are using an older version of N1MM+), you can open the WSJT Decode List from the N1MM+ >Window >WSJT Decode List menu choice:

WSJT DecodeList EWmenu

Opening this window will automatically initiate the UDP Server communications between WSJT-X/JTDX and N1MM+ for the transfer of duplicate/worked/multiplier status from N1MM+ to WSJT-X or JTDX. Once the window has been opened, you will do all of your operating from WSJT-X or JTDX, and not from the N1MM Entry Window. In fact you can minimize (but do not close) the WSJT Decode List, and you can also minimize all of the N1MM+ windows temporarily if you want to to free up screen space.

Log contacts in WSJT-X or JTDX, not in N1MM+

If something (such as anti-malware software, or a configuration error in one or the other of the programs) prevents the transfer of logging information, you need to fix that. For example, you may need to configure a firewall in your anti-malware program to permit N1MM+ and WSJT-X/JTDX to use the UDP or TCP ports they need to use to communicate with each other. DO NOT try to bypass the automated logging by entering exchange data directly into the N1MM+ Entry window and pressing Enter to log it. Doing so may result in incorrect information being logged.

Using WSJT Decode List

WSJT DecodeList

With the WSJT Decode List enabled, a list of up to 30 recent callsigns will be displayed with row colors indicating each callsign’s contest priority (by default, these will be grey for dupe or zero points, blue for workable but not a multiplier, red for new multipliers). Callsigns in the corresponding WSJT-X/JTDX Band Activity panel will reflect those same contest color priorities as a background color. The only callsigns that are marked are callsigns of stations calling CQ. Callsigns of stations with QSOs in progress are not marked and do not appear in the WSJT Decode List.

To initiate a contact with a listed station, you may click on a callsign in either location (in the Logger’s WSJT Decode List window, or in the WSJT-X or JTDX Band Activity window). A single click just transfers the call sign and grid square information without enabling transmit; if the “Double-click on call sets Tx enable” option has been checked in WSJT-X, a double-click does the same and also enables transmit on the next valid time slot. Note that if you double-click on an “old” callsign, i.e. one that was sending CQ during the 15-second sequence before the most recent one, WSJT-X/JTDX will not start transmitting until the correct time slot for calling that station (e.g. if the other station called CQ on an “even” time slot starting at 0 seconds or 30 seconds, WSJT-X/JTDX will only call that station on an “odd” time slot starting at 15 seconds or 45 seconds).

When you click or double-click on a callsign, either in the WSJT Decode List window or in the WSJT-X/JTDX Band Activity window, that call sign will also appear in the N1MM+ Entry window. This is for the purpose of doing a dupe/multiplier check; it is not part of the logging process. Do not enter the exchange into the Entry window. Simply complete the QSO in WSJT-X or JTDX, up to and including the point where the QSO is logged. After completing and logging a contact in WSJT-X or JTDX, that contact will be logged in the WSJT-X or JTDX ADIF log and the N1MM+ contest database simultaneously.

Do not type anything into the Entry window or any other N1MM+ window; in fact, it is possible to operate in FT8 or FT4 with all of the N1MM+ windows minimized to the Windows Task Bar and still have all of your FT8/FT4 QSOs recorded in the N1MM+ log. It is not necessary that the WSJT Decode List window in N1MM+ be visible; it can be minimized to the Task Bar and will still carry out its function of relaying dupe/multiplier status to WSJT-X or JTDX.

When a callsign is listed in the WSJT-X or JTDX DX Call field, the Decode List interface will persistently copy that callsign into the N1MM+ Entry Window callsign field (for example, the call will stubbornly reappear after using <Wipe> to clear the N1MM+ Entry window). After you have completed a QSO in WSJT-X and it has been safely logged, you can use F4 in WSJT-X to clear the DX Call field while still running WSJT-X. This will clear the callsign field in the Entry window as well. If you are entering a contest that allows multiple modes, having WSJT-X or JTDX put calls into the Entry window, or having it clear the Entry window, is definitely not something you want to have happen while you are using another mode. Therefore, you should always close the WSJT Decode List window and shut down WSJT-X/JTDX before changing to a non-WSJT mode.

To change modes from a WSJT mode to a “normal” N1MM_ mode (CW, SSB, RTTY, PSK31/PSK63), type the name of the mode into the Entry window and press the Enter key. If this does not close the WSJT-X or JTDX program automatically, close it as well. Either way, the WSJT Decode List window should close (if it doesn’t, close it as well). Now QSY to the frequency you want to operate the new mode in (for example, by typing the frequency into the Entry window) and carry on operating in that mode. To switch from that mode back to FT8 or FT4, either use the >Window > Load WSJT/JTDX menu item, or just type FT8 or FT4 into the Entry window. Then, if the Decode List window does not open automatically, use the >Window > WSJT Decode List menu item to open the WSJT Decode List window.

WSJT Decode List FAQs

Rig Control – Can both WSJT-X and N1MM+ control the radio?

Yes, if you are calling up WSJT-X from within N1MM+ using the >Window > Load WSJT/JTDX menu item and N1MM+ and WSJT-X have both been configured appropriately. When you do this, N1MM+ handles rig control on behalf of WSJT-X, using the same technique as is used by the DXLab Suite Commander program (which is why WSJT-X is configured to use “DX Lab Suite Commander” as its rig control method).

If you run WSJT-X stand-alone instead of from within N1MM+, the only way that both programs can control the radio is if you are using a port splitter or virtual serial port application. If you do not have some kind of port splitting program to allow two programs to control the radio simultaneously, then plan on disabling rig control from N1MM+ and allowing WSJT-X to “drive” the radio settings whenever it is active. If you want to make contacts in RTTY, you will have to close WSJT-X or disable its rig control, re-enable rig control in N1MM+, and put N1MM+ into RTTY mode. Experimentation prior to the contest is highly recommended – see also FAQ #5.7 below.

There are a number of possibilities for port splitting. If your radio is one of those that supports one of these programs, one of the Win4K3Suite/Win4YaesuSuite/Win4IcomSuite programs may do what you need. N8LP’s LP-Bridge program is another possibility, although with at least one caveat — apparently, WSJT-X might only work with LP-Bridge’s Virtual Serial Port #1, i.e. the leftmost virtual port in the LP-Bridge window. Yet another option may be to use the DXLab Suite’s Commander program for rig control, configure WSJT-X to use Commander instead of controlling the rig directly, configure Commander’s “secondary CAT port” to lead and follow the primary port and use the Kenwood protocol, then configure N1MM+ to use the Kenwood protocol for radio control and connect it to Commander’s secondary CAT port via a connected virtual serial port pair (com0com). This is described in the DXLab Suite Wiki under “Interoperating with Software-Defined Radios”, substituting N1MM+ for the SDR software. Note that the only rig control functions supported by Commander’s secondary CAT port are frequency and mode control. Advanced control functions such as CAT1ASC macros, RIT control, filter width commands and PTT via radio command from N1MM+ will not work using this method. Note also that this port splitting method cannot be used if you are running WSJT-X/JTDX from within N1MM+.

When using one of these methods, you may encounter problems with N1MM+ changing your radio mode from the setting required by WSJT-X for data versus the mode setting in N1MM+. Generally speaking, the radio mode you use for WSJT-X will be the same as the radio mode you would use for PSK. Therefore, if the Mode sent to radio is set up correctly under the Mode Control tab in the Configurer, then N1MM+ must be put into PSK (digital) mode (from the Entry window) whenever you are operating from WSJT-X. If you leave N1MM+ in RTTY mode (or CW or SSB), it may put the radio into the wrong mode (e.g. FSK or LSB for RTTY instead of USB or USB Digital for PSK/WSJT-X).

If you do share radio control using one of these methods, some of N1MM Logger+’s features may not work. The N1MM+ Development Team is unable to help with such situations, since the port splitting method used is outside our control. If you encounter problems with N1MM+ while using one of these methods, then before reporting a problem, please test to make sure you can reproduce the problem with no port splitting program active or involved. If you cannot reproduce the problem with no port splitting software in the picture, we are not likely to be able to resolve it.

No Rig Control – Does it work without rig control?

Yes. It is possible to use WSJT-X without rig control – but this requires some careful attention to detail when changing bands. You will need to change bands manually in both programs every time you change bands on the rig. Checking for duplicates and multipliers will not work correctly if the N1MM+ program is not set to the band you are operating on. Operating without rig control also means that some of WSJT-X’s features, notably the “Split” or “Fake It” techniques used to keep the sound card audio in the 1500-2000 Hz “sweet spot”, as well as the automatic choice of operating frequency depending on the mode selection, will not work.

Compatibility with JTAlert – Can I run JTAlert at the same time?

No. The current versions of JTAlert and N1MM+ do not permit port sharing. You must close JTAlert for the WSJT Decode List to function. Furthermore, if you enable both the WSJT-X -to- N1MM+ logging interface and the JTAlert logging interface (without using the WSJT Decode List window in N1MM+), your contacts will be double-logged into the N1MM+ contest database.

Supported Contests – Does this only work with specific contests or can I use it with my general log?

You can use the WSJT Decode List with your general DX log or with one of the contests supported by WSJT-X.

For general logging, use WSJT-X in normal non-contest mode and use the DX log in N1MM+. Make sure the Mode category in the Contest Setup window for your DX log is set to SSB+CW+DIGITAL. If you leave it at the default SSB+CW, digital mode contacts made from WSJT-X may not be logged correctly, and the dupe checking will be wrong.

For contest logging, if the contest exchange is different from the normal non-contest exchange in WSJT-X, you will need to set the contest mode in WSJT-X under the Advanced tab in the Settings window. Check the check box called “Special operating activity” and then select the applicable contest and if necessary, fill in the contest exchange box. In N1MM+, open a contest log of the appropriate contest type, make sure the Mode category includes DIGITAL, and in the Entry window, put N1MM+ into Digital mode (e.g. by typing FT8 or FT4 into the call sign box and pressing Enter).

Callsign Colors – What do the callsign colors mean?

The callsign colors displayed by WSJT Decode List and transferred as background colors to the Band Activity window in WSJT-X/JTDX are derived from your N1MM+ settings found in the >Config >Manage Skins, Colors, and Fonts >Colors window under 3. Callsign Background Colors. By default those colors are:

  • Grey = dupe or non-workable (zero-point contact)
  • Blue = normal (new contact but not a new multiplier)
  • Red = new multiplier
  • Green = double multiplier (not applicable in contests supported by WSJT-X at this time, but may apply in future)

Serial Numbers – Will serial numbers from the two programs be in sequence?

In a word, no. If you make some contacts from N1MM+ (in RTTY, for example) and some contacts from WSJT-X (in FT8, for example), the serial number sequences from the two programs will not be in sequence. There is no way for WSJT-X to know what serial numbers you have used in N1MM+, so it will issue its own serial numbers independently of what N1MM+ does. Don’t try to edit serial numbers to make the sequence look pretty – just accept whatever the two programs generate. What matters most is that your log reflects accurately what your software actually sent.

What do I need to do to switch between CW/SSB/RTTY and FT8?

When you run WSJT-X or JTDX from the N1MM+ Entry Window’s >Window > Load WSJT/JTDX menu item, you can change modes simply by typing the name of the mode (FT8, FT4, RTTY, PSK31. PSK63) into the Entry window.

If you are not using the full N1MM+ to WSJT-X/JTDX integration, switching modes is more complicated. To go from SSB, CW or RTTY to FT8 or FT4, first change the radio’s mode to the mode you use for FT8/FT4, then (unless you have some kind of port sharing working) disable rig control in N1MM+ to allow WSJT-X to control the rig (in the Configurer, change the Port column for the rig control port to None) before starting WSJT-X. Make sure the rig’s IF filtering is appropriate for FT8/FT4 (wide), and tune it to a frequency where contest FT8 or FT4 QSOs are taking place (on the HF bands, the regular non-contest FT8 frequencies are not good places to try to make contest QSOs). Open the WSJT Decode List window in N1MM+. Note that if rig control is disabled in N1MM+ in order to run WSJT-X stand-alone, then whenever you change bands in WSJT-X or on the radio, you also have to change bands in N1MM+ to ensure that the band in N1MM+ agrees with the band the radio is on, otherwise dupe and mult checking will be incorrect.

To go from FT8 or FT4 to RTTY (or any other mode operated from N1MM+), first close the WSJT Decode List window and WSJT-X. If you were running WSJT-X in stand-alone mode and you do not have some kind of port sharing method active to allow both programs to control the rig at the same time, enable rig control in N1MM+ by setting the Port listbox for the rig control port to the port used for rig control. Make sure the rig is set to the correct mode with the appropriate filtering, and tune it to an appropriate frequency (presumably not the frequency you were using for FT8).

Note that if you leave WSJT-X running with the WSJT Decode List window active while you are trying to make RTTY contacts, WSJT-X will take control of the N1MM+ Entry window and you will be unable to log RTTY contacts. WSJT-X is persistent in sending the characters from its DX Call field into N1MM+’s Entry Window callsign field. Even if DX Call is empty (blank) it sends a blank to N1MM+ – wiping out anything you may try to enter in N1MM+. You must close the WSJT Decode List window and the WSJT-X program when operating from N1MM+. Conversely, you must do all of your FT8 and FT4 operating from WSJT-X. Do not try to enter anything into the N1MM+ Entry window while WSJT-X is active and the WSJT Decode List window is open.

Why are my FT8 contacts being scored with zero points?

If your FT8 and FT4 contacts are being assigned zero points in the Log and Score Summary windows, it is likely that you have selected the wrong Mode category in the N1MM+ contest setup. Use the File > Open Log in Database… menu item to open the contest setup dialog window, and change the Mode category from RTTY to DIGITAL (ARRL RTTY contest), or from SSB+CW to SSB+CW+DIGITAL (VHF contests, general DX logging).

The logging interface into N1MM+ does not refresh the contest score when you change the contest category. Use the >Tools >Rescore Current Contest menu item to rescore previously-logged QSOs, and the score should be accurate thereafter (as long as you don’t change contest settings again).
