[Elecraft] CW with my K3s and KX3

A bit off topic but I think many Elecraft users are CW people. My station is completely set up for good CW (K3s, KPA500, KAT500, KX3 with paddle, Vibroplex Code Warrior) and I can send and copy relatively well up to about 20 WPM but I seem to lack the interest to grab the horns and actually eng
