Adriano, The K3 has full digital interface isolation built in. Using nothing more than 2 cables to the computer soundcard you can operate using VOX. Adding a serial cable between the computer and the K3 can add other options.
The only advantage for using an external digital interface is that many provide an added soundcard. That is an advantage for those who use a laptop with only USB connections and an inadequate soundcard. OTOH, an external USB soundcard may be a better solution than the full "digital interface". My vote is for the KISS principle - no external interface, the K3 already has it built in. 73, Don W3FPR On 1/11/2012 3:03 PM, Adriano Perazio wrote: > New on digi modes, i´m wondering what´s the benefits of adding an interface > to the K3? > I´ve been working with the K3 “internal” interface and seems to work very > well.
