Contesting with fldigi

Fldigi supports a full range of contests, either using it's internal logbook or when linked to one of the N3FJP loggers. Each contest's unique data exchange is captured either in a generic multi word exchange field, or in contest specific fields that are displayed in the main dialog logging group.

Contesting with fldigi's built-in logbook

Select the contest type from the Contest combo:

UI Contest

If you select the State QSO parties, you need to make a second selection for the specific state, province, area, or region contest in which you will be participating.

UI Contest

The serial number out (#Out) is automatically initialized and updated by the built-in serial number generator. You can enter the appropriate exchange information via the keyboard or mouse. Text in the Rx pane can be selected by mouse left-click / right-click. Make your selection and the info is placed in the correct text box. Note that the popup menu changes with the QSO logging view and also with a change in "Quick entry". A full description is found in the description of operating the Logbook. The important thing to note for contest operation is that the Call and Serial # are single word captures. The Xchg capture can be either single word or multiple word (mark / right click). If the Xchg field has text contents then the new capture is appended to end of the current text in that field. That means you can point to the word representing the field, right click and select from the menu. You do not need to highlight the text for the word capture. You can very rapidly fill in the serial number and the exchange data (even if multi value) by simply pointing and right clicking on the desired word.

Set up the Generic contesting on the UI/Contest tab. The Send Xchg control is the text you want the appropriate macro tag. ie...if the contest requires RST and name you would fill in the Exchange Out box with your name. The contents of this field are accessed from a macro with the <XOUT> tag. You will also need to check the RST always 599 box as this is the de-facto signal report in contests.

If you are participating in a CW contest you may want to select the "Send CW cut numbers", cut numbers is the norm for a CW contest. The cut numbers will send N for 9 and T for zero.

The next box contains the needed requirements to use serial numbers for a contest. You will always want to use leading zeros, start with 1 and use 3 digits. Press reset to initialize the #Out QSO field to the Start number.

Check the appropriate fields for determining if this is a duplicate call. If a duplicate is detected the Call entry will be highlighted as shown in the "Dup Color" button. Pressing this button opens a color selector so you may customize the color. There are many choices to alert you to a duplicate contact. The duplicate is based on the logical AND of all of the fields to be checked. The DUPE is cleared when you press the clear QSO log button (the brush icon).

After you have filled in all the required information, make sure you save and close.

Remember YOU MUST click the Reset button in the Serial number panel for the serial number counter to be initialized. You should also press the QSO clear button (broom) in the QSO entry widget for the other changes to take effect.

It would be best to create a new log for each contest. You create a new log by selecting the menu item File/Logs/New logbook. The default new log name will be newlog.adif on Linux and newlog.adi on Windows. You can rename the new log file now or later by using the system file manager or when you save the log. The import/export feature of fldigi will allow you to export the log into your everyday logging software or the built-in fldigi logbook.

You can check for duplicates by any combination of the specified named fields. You can also specify that the duplicate had to occur within a given time interval. Some VHF contests allow a duplicate CALL after a given time interval.

Field Day Contest

The log fields and associated Rx Text popup menu changes to appropriate fields when the Field Day check box is enabled on the contest configuration tab:

The field day station station callsign is your fldigi user callsign. Enter the operator's call (if different). Enter the Class and Section for your station. These will all be available as macro tags for writing macros appropriate for participating in the field day event.

fldigi can connect to external Field Day logging programs such as N3FJP's FDlog and/or a TclTk application called "fdserver" that is a part of the family of fldigi programs. fdserver operation is described in a separate document.

Additional instructions on the field day server is available at Field Day Server setup.

Capturing Rx data strings

Capturing exchange text from the Rx text panel has been simplified for contest operations. All text capture is based on a single mouse left click on the word of interest, or on the first word in a sequence:

  • LEFT click - capture single word
  • SHIFT LEFT click - capture two words
  • CONTROL LEFT click - capture three words
  • SHIFT CONTROL LEFT click - capture four words

The capture text parser behavior is keyed to the selected contest. The program will attempt to recognize specific phrases such as RST exhcange, States/Provinces (both long and abbreviations). For each contest there is a preferred capture order. The capture order for the specific contest is displayed on the contest configuration tab. Use the capture order to assist the parser.

You can also capture text using a RIGHT mouse click on the target Rx word. A pop-up menu will open with selectable fields that are keyed to the selected contest. You may need to use the right click paradigm when fields may be conflicting. For example a contest may require both RST and a SERIAL number, both of which may have similar values.

Contest Macros

This section contributed by W3NR, Ed

It is recommended that you make a separate macro file for contesting. Start with the generic set of macros and modify them as described in this section. Then save the modified macros with a suitable file name such contest.mdf. This will give you 48 macros to use based on the type of contest you are entering.

Take a good look at the following examples and you will notice there are no commas, hyphens or other extraneous items. Your contest exchange should be brief and concise. These are examples of what not to do:

  • w3nr you are 599 in Alabama your serial number is 001-001-001 how copy ??
  • hello ed thanks for the call you are 599-599-001-001-001 QTH Alabama back to you

Capturing data from that kind of exchange is nearly impossible. Contest macros should be written to expedite the exchange of data.

When you enter a contest you have to decide whether you are going to sit on one frequency and call CQ (Run) or are you going to tune the band looking for stations to work (S&P). So lets set up some macros that should cover both cases.

Several new macro tags have been created to facilitate contesting, these include the following tags.

<LOG> add QSO data to the logbook & clear the QSO data fields
<CNTR> insert current contest serial number into the text stream
<INCR> increment contest serial number
<DECR> decrement contest serial number
<XOUT> contest exchange
<QSOTIME> current log time in Zulu HHMM format
<LDT> local date time
<ILDT> LDT in iso-8601 format
<ZDT> Zulu date time
<IZDT> ZDT in iso-8601 format
actual time of execution of the macro ... useful where exact times are used to match contest log submissions
save entire contents of the expanded macro text to the "Exchange Out" field in the logbook
mark the beginning of a text string that is to be saved to the "Exchange Out" field in the logbook

mark the end of the text string that is to be saved to the "Exchange Out" field in the logbook
note: <SAVEXCHG> and the <XBEG>...<XEND> macro tags are mutually exclusive

<XBEG>...<XEND> is given priority if both all three are specified in a single macro

See Macros for additional information on editing and using the fldigi macro system.

RUN Macros

We need just a few, starting with a CQ macro - Put this in the F1 key definition

cq test de <MYCALL>  <MYCALL>   cq k

Notice that I left 2 spaces between my call and 3 spaces at the end before the k. This will make it easier for a station to grab my call and the k on the end eliminates garbage characters before my macro finishes. The tx/rx are on separate lines as I want to be sure my macro is on a line by itself and not mixed in with screen garbage. This does not apply to the CW mode as there is no CR/LF function in CW. fldigi will convert the CR/LF to a space in the CW mode.
Now the exchange macro - Put this in the F2 key definition

<CALL> 599  <CNTR> <CNTR>  <XOUT>  <XOUT> <CALL>  k

Why do I have his call at the beginning as well as the end, to make sure I have copied his call correctly. You will also see that I have not as yet logged the contact,why, well are you sure he does not need to correct his call or ask for a repeat.

You are asked to repeat the exchange, you can just re-send the exchange macro, this verifies all of the information. Now he sends you his info and if you have copied it correctly you need a TU macro. - Put this in the F3 key definition.

qsl tu qrz test  <MYCALL>  k

Here we have done all the necessary items to complete the exchange. Notice that I did not log the contact until after everything was correct. I have fldigi set to clear on save, so when the <LOG> part of the macro executes the QSO area is cleared.

Thats the end of my RUN macro setup, told you it was rather simplistic and generic.

S & P Macros

I rarely if ever use S&P, but there are times I need to, especially if my QSO rate drops while running. Again the macros are very generic with only the needed info. If band conditions warrant you may want to send your call 3 times. Put this in the F5 key definition


Why just my call ?? Well I assume the other guy already knows his call !

The exchange macro is basically the same as the RUN macro. Put this one in the F6 key definition

599  <CNTR>  <CNTR>  <XOUT>  <XOUT>    k

As you see I have not as yet logged the QSO or incremented the serial number. This is the final S&P macro. Put this one in the F7 key definition.


Now this is the most important macro you will ever need......trust me. Put it where you won't fail to find it. How about F9 ?

agn  agn  k

You will see that it is used many times during a contest, especially with weak stations and heavy QRN/QRM.

  • <QSOTIME> - time sent in Tx stream
    • repeat execution of <QSOTIME> before a <LOG> macro or a save to log button press will resend the original time
  • <LOG> macro or a save-to-log button press appends the QSOTIME to the STX_STRING field in the adif log record and clears the QSOTIME.
  • <XBEG> - use at end of a contest exchange to save the entire exchange string in STX_STRING
    • usurps QSOTIME if both are contained in same macro text, ie:
      "<RST> <CNTR> <QSOTIME> <SAVEXCHG>" will send the exchange as
      599 024 1125
      if RST = 599, Counter = 024 and time of execution is 1125
    • repeats the same as <QSOTIME >
  • <LOG> - or a save-to-log button press saves the associated macro text (after expansion).
    • QSOTIME and the saved exchange text are cleared after the save occurs.

An example of the SAVEXCHG macro tag


Where RST = 599, CNTR = 0125, XOUT = AL, QSOTIME = 1433

Will save this string to the Exchange Out field in the logbook: "599 0125 AL 1433"
Please note that you should not include any text or macro tags that are not to be a part of Exchange Out. If your macro had this:



the saved Exchange Out field would contain: "W3NR UR 599 0125 AL 1433 de W1HKJ k"
Probably not what you want. Use separate function keys for the "<TX>CALL ..." and the "de <MYCALL> k<RX>" or use the next set of macro tags


These two macro tags are delimiters for capturing the transmitted exchange data, for example:


Will place the expanded <RST> <CNTR> <QSOTIME> into the Exchange Out field of the logbook when the contact is saved. This is much better illustrated with a screen shot. This one shows the macro editor contents, the logbook entry in Exchange Out, and the transmit text buffer.

Contesting with N3FJP logger connection

Fldigi and the N3FJP logging software have been interfaced to form a very powerful combination that allows the avid contester to perform CW and digital communications in the most popular ARRL, National, International, and State contests. This combination also assists the Handi-ham in communicating in CW. They allow the operator to send and receive contest exchanges as well as control their rig. The N3FJP logger behaves as a log data base server and fldigi the modem client for the purposes of data exchange. The N3FJP logger can reside either on the same host computer (Windows) or on a LAN connected Windows host computer. The fldigi/N3FJP combination has been tested on a single Windows 7/8/10 computer, and on a LAN with fldigi running on a second Windows computer, a Linux computer, and an Apple OS-X computer.

Although the contests are varied, certain parts of the set up are the same for all. These include the Sound Card (Rig Interface such as Rig Blaster, Signalink, or home brew) and the API (Application Program Interface.), and transceiver control. Both fldigi and the N3FJP program can provide transceiver control. You should use fldigi / flrig for transceiver control as then can provide a broader range of control functions.

The N3FJP logger will maintain and provide the SENT serial number to fldigi. That serial number will be used in all macros which reference the sent serial number.

The N3FJP logger software is independently sold and distributed by Scott and Kimberly Davis. Download the appropriate logging software from http://www.n3fjp.com.

Either fldigi or the N3FJP logger can be started first. When so configure fldigi will periodically attempt to connect to the logger. The two programs can reside on a single or multiple computers with LAN access. The N3FJP logger will only run on an MS operating system. fldigi can be on any of the supported operating systems. The connection has been tested between Linux, OS X, and MS operating systems.

N3FJP logger setup

  • Click on Setup and configure your station information.
  • Set up API. This is necessary even if both fldigi and the logger are on the same machine. Select API from the Setup menu.
    Check the box in the upper section for API port 1100.

Fldigi setup

  • Open configuration dialog to the UI/Logs/N3FJP... tab

    N3FJP connect
  • Enter the LAN address, either as the machine name or it's numeric uniform resource locator, i.e: LENOVO-DUALBOOT (
    If both fldigi and the N3FJP logger are on the same Windows computer, then the machine address is
  • Check the box "Enable data stream" to view the connect and data transfer process.
  • Check the "Connect" box

fldigi should connect to the logger with a few seconds. You will see the connect stream processing as above, and the GREEN connect triangle should\ illuminate.

Disconnecting is as simple as unchecking the "Connect" box.

fldigi's contest selectors will be set by the initial information exchange with the N3FJP logger. Exiting the N3FJP logger and starting a different one will be reflected in fldigi's contest configuration almost immediately. The fldigi main dialog title bar and the fldigi logging controls will reflect the change in contest usage. Here is an example for an automatic connection to the CQ WW DX contest

CQ WWDX contest

fldigi will query the N3FJP logger for duplicate checks. Both the N3FJP logger and the fldigi logging control for CALL should provide a duplicate indication.

For more information on fldigi/N3FJP loggers see N3FJP Log/Contest Setup.
