[Elecraft] Clean CW signal

[David Walker]

I notice when I listen to my CW on a separate reciever that there appears to be a slight husky modulation to the carrier.  It's not located near a power supply - so I've eliminated magnetic field interference.  I do have a manual MFJ tuner located 3 ft away. My antenna is a G5RV that runs across the roof of the house.  I have a 6:1 balun at the 300/50ohm junction.

I was wondering if this slight raspy noise on the carrier is normal or if I have some issues with my setup.  

Tonight I will set my K2 up to beacon and go for a walk 400m away from the house to see if it shows up further away.  But any advice from you guys would be appreciated.  It might save me a lot of time :-)  I do not recall noticing this before I did the CW shaping upgrade, so I am wondering if I am just noticing this now.
