You should see the red volume bar move due to incoming audio from SmartSDR.Ĥ) Open Ham Radio Deluxe and setup SmartSDR as the radio type. Make sure the 'TX' is also clicked and red. It should increment to COM5.ģ) Open DAX Control Panel and click the '1' button and verify it turns blue in color. Click 'Add a Port', change the Port Type to PTT, and check 'RTS' and 'DTR' on the 'Pin Change' selection. In this example, COM 4 is for CAT, and COM5 is for PTT.

I find that DM780 responds faster using a direct PTT connection to the radio rather than sending PTT via HRD.

Make sure the DAX button is clicked in the P/CW tab on the right.Ģ) Switch to SmartCAT and add another COM port for PTT trigger. Click the DAX tab in the slice and set the channel to 1. Please also make sure you have installed SmartCAT, and it is running.ġ) Open SmartSDR and connect to your radio. I will demonstrate transmitting on 20M PSK31 using Slice A with a single Pan Adapter. This guide is to show how to configure SmartSDR and HRD v6.2 for use with DAX.
