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, area, region contest in which you be participating.

UI Contest

Enter the exchange you want to send. You can force the RST in/out to always be 599. That seems to be a norm for many contests. When operating in a CW contest you can have fldigi send cut numbers, T for 0, N for nine.
The serial number can be set to use leading zeros. You can specify the starting number for the sequence and how many digits are sent, ie: 0024. Pressing Reset will set the starting number to the QSO logging serial out field. See Contest How To for more info.

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

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.

Since the contests differ greatly in their exchanges, these instructions will be rather lengthy and will have many screen shots. These instructions will be broken down by contests that are similar and require similar settings.

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.)

The first thing that you will need to do is to bring up the N3FJP program for the contest that you want to participate in. To do this go to http://www.n3fjp.com and select it from the Contest Logs drop down menu. The N3FJP logger software is independently sold and distributed by Scott and Kimberly Davis.

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 (
  • 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.

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

fldigi will follow suite as you stop and start various N3FJP loggers. The fldigi main dialog title bar and it's logging controls will reflect the change in contest usage. Here is an example for an automatic connection to the CQ WW DX contest
