[Elecraft] external soundcards for digimodes

[Lyle Johnson]

In casual operation, I doubt you'll see much difference. However, if you 
are planning on operating during a contest, or otherwise want to use a 
wide audio path (SSB bandwidth) with AGC OFF (so strong stations don't 
smother weak ones via AGC action) and with lots of signals 
simultaneously present, then you'll want a system with very low IMD.

The least expensive soundcard that I own that does a reasonable job with 
SDR (and by extension should do a reasonable job under the conditions I 
described) is the Creative Soundblaster MP3+.  This is a USB-based 
widget, and you can buy these from Creative's online shop, refurbished, 
for $14.99.
