[Elecraft] USB Sound Card

[Joel Black]

Tom,

For many years, I used a Creative Labs E-MU 0204. The last time drivers were written for that interface was late 2014 and it is no longer in production. When I upgraded to OS X 10.11, I could not use the interface because of some changes in OS X. I purchased a Focusrite 2i2 and cannot be happier (unless I had purchased the Focusrite 6i6 for more I/O). I regularly decode JT65 and JT9 in the mid -20s. I have had at least one JT9 decode at -27 using the Focusrite.

The 2i2 is available from most online big-box places for right around $150. All you will need to purchase the appropriate cables. With both the K3 (I know you said K2) and KX3, I use a 3.5 mm TRS to 1/4” T and R mono from radio out and a 3.5 mm to 1/4” mono to radio input. The Focusrite USB interfaces are red anodized aluminum and you can adjust both input from the radio and output to the radio with dials on the front. It also has a separate headphone stereo monitor that can be turned on and off with volume adjustment. The adjustments right on the front of the Focusrite make operation very easy.

73,
Joel - W4JBB
