 refusal
After installing FreeDV, I have been able to transmit, but have not been able to make contact at this time.
I cannot hear any signal at all on any of the bands.

I'm still trying to figure out if there's something wrong with the settings.
In a Facebook conversation, I learned about something called FreeDV!
I found this page
In the middle of that page, you'll see "About the current versionClick on the link "Click on the link
You can download it from the "Available Binary Releases" section further down on the page that opens
Clicking on the downloaded file will launch the installer
Press "Next" to proceed with a few things, including where to install the software.
Press "Install" and after a while the Python installation will start.

The first time you install it, it will take a while here, but just wait.
Before starting FreeDV, switch the DATA mode setting of the FTDX3000 from the menu.

Menu 67 MODE DATAPSK to OTHERSswitching over to
After installation is complete and FreeDV is started, Easy Setup is launched


If you are playing FT8, you can enter almost all of these settings and you're good to go!
However, only the microphone array will choose a headset or other device instead of USB.
In my case, I connected it to a FTDX3000.
FTDX3000 and ThinkPad X390 connected via USB cable

Select Mode, then select the frequency in ReportFreq(MHz) and press Start button to start reception.
Looking at FreeDV Reporting, Mode seems to be RADEV1

Maybe it's just my computer, but the mouse cursor stops responding for a few seconds after I press Start.
Spectrun Screen
Select [Tool]-[FreeDV Reporting] to see the band
When Track is checked, the frequency automatically switches to the frequency selected on the main screen.
