[Elecraft] First foray into K2 in digital mode...power source

[Leigh L Klotz, Jr.]

I found that if I power the SL1+ from the same 12v that powers the K2, I 
get ground loop noise.  I haven't tried pulling power out of the mic 
jack.  I use a small battery.  But these days when I use it with my K2 I 
use the RS232 rig control for keying and don't turn the SL1+ on at all, 
just using it for the isolation.
