2. Expand the Ports section to check for:
   • ICOM IC-705 Serial Port A (CIV) on COM4
   • ICOM IC-705 Serial Port B on COM5
3. Ensure both ports are present, indicating successful installation.

Step 7: Set Up WSJT-X Software

1. Open the WSJT-X application.
2. In the settings, ensure the Radio is set to ICOM IC-705.
3. Select the Serial Port as COM4 (CIV).
4. Set the Baud Rate to 9600.
5. Ensure the PTT method is set to CAT.
6. For Modulation, choose Data / Packet.
7. Enable Fake it for split operations if needed.

Step 8: Test the Setup

1. Click on the Test CAT button in WSJT-X; a green indicator means successful communication.
2. Test the PTT function to ensure the radio transmits correctly.
