Configure the Radio
Before we begin to setup DM780 to interface with the radio, we first need to setup the
radio side of the connection. When using the 3000 for PSK and other sound card
based digital modes. The data mode lets the radio use a different set of interfaces and
configuration settings for example from SSB use. Which is nice as it allows you to flip
between data and voice modes without having to reset a series of controls.
Enter the menu system and change option #65 PC Keying to DTR.
