[Elecraft] K-3: USB SignaLink for better RTTY decoding?

[Lorenz Koestler]

Hi Dick

I haven't much experiance with RTTY on different soundcards. But I 
noticed that the SignaLink interface is much better (lesser noise) then 
most integrated sound cards. Especially compared to the sound cards in 
notebooks.

One point is the galvanic isolation. But I think the biggest advantage 
of a SignaLink interface is the usability. The potentiometer are very 
useful to ajust the levels. Our local distributor in Switzerland ships 
the interface together with all cables needed for the K3.
