On the “Serial Ports” tab of the connect window the virtual serial port presented by SmartSDR CAT is visable. Next let’s start up HRD and setup the CAT connection to the radio. In the DAX Control Panel one final step before moving on, enable “RX Stream 1” by clicking on the “1” which will change the stream to active and the indicator to blue. I have outlined in red below the key configuration areas. In my example below I am running a 5Khz wide slice which while in the example is on a 20 meters PSK frequency, this setup works well across any of the audio based digital modes.įor DAX to work it must be enabled, the slice assigned a DAX channel, it is also a best practice to open up the receiver width to 5k with a corresponding change to the TX High Cut to match.

Since we are going through the effort of plumbing up the CAT connection, let us spend a little time setting up the virtual sound card for whatever tickles your fancy. The connection will not actually occur until HRD config is complete.

Also shown in the screen capture below, HRD is connected to this port. Below is the end result a Com11 CAT serial port assigned to Slice A. So I thought it a worthwhile use of time to create a similar posting for SmartSDR.Īs the FlexRadio documentation is excellent I will not spend much if any time providing details on how for example to create a port in SmartSDR CAT as the existing user documentation covers this in detail.įirst step is setting up a vitual serial port for HRD to connect to. My post covering the setup and use of the Yaesu FTdx3000 with Ham Radio Deluxe (HRD) gets hundreds of hits a week.
