fldigi with Icom IC-7300

fldigi is a free program used for various digital modes.

Thanks for visiting this page. It seems to have become the goto reference page for setting up  fldigi for the Icom IC-7300, and I will try to keep it updated.

This post describes the steps needed to get fldigi set up with the Icom IC-7300.

  1. Setup your 7300 as described in this post Icom IC-7300 Digital Mode Settings.
  2. Download fldigi from here: fldigi – Ham Radio Digital Modem Application
  3. Each transceiver needs a Rig definition. Some transceivers can work with the (not recently updated) Hamlib library, but not the IC-7300. Instead, you use the fldigi RigCAT settings. The specific rig description is available for the IC-7300 to download. So, you need to download the rig description file from here: ic-7300.xml before you install fldigi. It is an XML text file. Keep track of where you save that file for use in Step 5.
  4. Install fldigi by running the file you downloaded.
  5. Configure fldigi for the 7300.
    1. Open the Configure menu
    2. Open the Rig Control sub-menuj
    3. Select RigCAT from the left tab on the 2nd line.
    4. Click the user RigCat checkbox at the top of the box.
    5. The Rig Description File box should be blank. Click the Open… button, and then use the file selection dialog to select the ic-7300.xml file you just uploaded in step 3.
    6. Baud Rate of 19200 or 38400 should work.
    7. CAT command for PTT should be selected.
    8. Select the correct Device (will be a COM#). The actual port number will vary depending on your computer, but will be the one connected to Silicon Labs CP210x.
    9. Click Initialize and Save, and you should see things start working on the fldigi main screen.
  6. The introduction to fldigi is found here.
