[Elecraft] USB Support - K3, K2?

[Leigh L Klotz, Jr.]

Screenshots I have seen of the TigerTronics USB show crud at the <200Hz 
level.  I don't have one and haven't tested it.  I use a silver (pre 
iPod white) Griffin iMic, and it has a slight amount of 60Hz noise on it 
but much les than I have seen on the TT.  I use a TT SL1-+, but don't 
use its vox feature on the K2 (cat control).
