[Elecraft] Need local help

[Barry LaZar]

Jim,
      The SignaLink sound card is quite adequate for running digital 
modes on HF, and it appears to be better than the one in my Toshiba 
Satellite laptop. However, I do use a professional level USB card for my 
panadapter which is far more demanding. And, PTT is less clunky if 
you're not knowledgeable enough  to set VOX properly.

     There are some secondary, subtle, issues with running using the 
built in software for RTTY, CW, and PSK on the KX3. Those are you can't 
run the other modes should you desire and you can't see multiple streams 
of data simultaneously which is very useful if you looking for picking 
up awards.

     Using an external sound card frees up your computer sound card for 
other things while you demod/decode digital signals. For the cost of a 
SignaLink USB, or equivalent for about $100, you open up a layer or two 
of additional flexibility. My interface is permanently in my KX3 audio 
line with my amplified speakers coming off the Aux. on the back of the 
I/F. I can switch modes by just invoking  data a mode on the KX3 and 
replacing my mic with the cable from my interface.

     I interpret  what you are saying as being heavily biased toward 
operating on the digital modes. That's OK, but I use CW and phone as 
much if not more. So, I designed my station for ease of mode switching 
and maximum performance.

Vy 73,
