An important step in setting up DM780 is the configuration of the Radio Pane. On the DM780 top menu click on VIEW > then click on RADIO and the following Radio Pane will appear on the right hand side of the DM-780 display.
Your radio pane may NOT look EXACTLY like this but we will still be able to get the basics here.
The Radio Pane MUST be configured before you will be able to transmit any data from within DM780.
From here, click on the "Configure" icon on the Radio Pane toolbar as indicated by the red arrow in the image to the left. This opens the Radio Configuration Options page.
In the image above you will first see the HRD User interface information. Be certain it shows an "Address" of "localhost" and a port of "7809". Do not change the “Address” or “Port” settings as this will result in DM-780 not being able to communicate with the other HRD modules. Be certain there is a check mark in the box to automatically connect, then click on the "Connect" button.
There MUST be at least a "TX" button configured in order for DM780 to key your radio from within the digital modes, so, our next step is to place our cursor on the button marked "TX" and left-click. This will open the button options screen as seen below.
Once this is open, select and highlight "TX" as shown above, and click the "OK" button on the bottom of the Select button menu. This activates the TX button in the Radio Pane.
N o t e : There is one exception to setting the “TX” button. If you are
configuring the “TX” button for the Kenwood TS-590, 590s or 590sg, you must select “TX Data” from the Select Button list.
Now, all you do is click the "SAVE" button on the bottom of the configuration window and you will be returned to the main DM780 window.
You should now be able to transmit the AFSK digital modes in DM780 provided you have your soundcard configured properly and the PTT option set correctly in the DM- 780 Program Options.
