[Elecraft] What's best Soundcard Interface for KX3

[Robert Nobis]

George,

Many laptops do not have a good quality built-in sound cards. Their performance for very weak signals typically is not as good as using an external sound card.  You might want to test your internal PC sound card before you go to Brazil. If your internal sound card is able to consistently decode JT65 signals at levels below -19dB (for example -20 to -26 dB) it is probably acceptable.

You might wish to review Jim Brown’s (K9YC) Tutorial on sound cards:  http://k9yc.com/USB_Interfaces.pdf
