[Elecraft] NaP3 and KX3 connection

[Don Wilhelm]

Ron,

The best source of knowledge for questions about NaP3, Com ports, sound 
cards, and other related questions can be found on the LP-Pan Yahoo 
group.  Larry (N8LP) and others are quite responsive.  There is also a 
lot of helpful information at Larry's website www.telepostinc.com.

Yes, an add-on high end sound card will normally have a lower noise 
floor than the ones built into a computer, even if the other specs are 
equal.
