[Elecraft] RTTY/PSK interface for the K3

[Don Wilhelm]

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,
