Getting Started with HF Digital Modes

The following article intends to provide information on where to download free software to operate on various digital HF modes, and to provide some basic station configuration information.

This article covers multiple software applications, including:

Basic FLDIGI Configuration

This section is under development.

Obtaining NBEMS Software

The important applications to install for full NBEMS support include fldigi, flarq, flwrap, flmsg and flamp. Although you’re probably going to use fldigi, in most cases, it is a good idea (if you want to have full EMCOM capability available) to download and install the full NBEMS suite.

More information on NBEMS can be found by clicking here.

For the links for NBEMS software below, you want to download the image that is for Mac OS X while running on an Intel compatible processor. These are indicated by seeing _i386.dmg in the file name. Windows users would use the filenames that include _setup.exe.

When configuring fldigi to communicate with your radio, you will need to have a serial connection (requires a USB to Serial converter on the Mac) and the appropriate setup files. For Windows, if the radio has a USB interface, a Virtual COM Port driver may be available and would avoid using the serial interface. An xml file will be needed to configure fldigi to interface to the radio. You can download an xml file for your radio by clicking here, and then selecting the folder for the manufacturer of your radio.

Once you have the xml file downloaded, fldigi can be easily configured to talk to the radio.

Obtaining WSJT-X Software

[APP ICON] Version 1.8.0-rc1 of the WSJT-X software for Mac OS X, which is used for the JT65, JT9 and FT8 modes, by clicking here. Windows users can click here.

Please note that the above version of WSJT-X is a preliminary release (which adds FT8). I would expect that a final release will supersede the above link at some time in the near future, and should be available from the main WSJT-X page. The main page, and on-line documentation, can be found by clicking here.
