[Elecraft] k3/psk on laptop

[Simon Brown (HB9DRV)]

Limiting factors - well first you should try a side-by-side comparison of 
the average internal laptop soundcard and a high-end solution.

With poor soundcards you get:

* Reduced dynamic range, (weak signals will be lost)
* Intermodulation.

You are limiting a very good RX by using a poor soundcard. Good soundcards 
will meet the K3's RX dynamic range spec more-or-less and deliver a faithful 
signal to your software. Until you try good, bad and ugly side-by-side you 
don't know what you are missing.

Also - how do you know that you have not suffered degraded performance 
unless you compare two cards?

Using old laptops / soundcards with the K3 is like using a Ferrari 360 with 
$30 tires.
