[Elecraft] K2 Signalink USB

[EricJ]

I  also use the Signalink USB with a K2 with a little different layout.

I used Don's audio board, but I used a tiny 10K trimpot in place of the 
voltage divider for output. I mounted it on the left side panel with 
foam tape. You can easily remove the side panel for access to the amp. 
The output goes to a jack on the rear panel in a hole for adding the 
transverters.

Since I didn't know what might be needed for levels and wasn't sure I 
wanted a perf board accessory in my K2, I wanted more access than if I 
stuck it behind the front panel. I anticipated having to go back in 
several times, but that didn't turn out to be the case. I like Dennis' 
approach in hindsight as there is only one connecting cable between the 
K2 and the Signalink.
