[Elecraft] K3: noise using MFJ auto-tuner (K9HXO)

[Bill Miller]

My newly acquired K-3 and I are getting acquainted and I'm loving the rig. I am newly re-licensed after many years off and finding lots of QRN. Not news to anyone, eh? Well, I am using an MFJ 993 tuner and just for giggles I turned it off today and the S meter dropped several points (all noise).
 
I've considered getting a KAT-3 and unless someone has a solution to the MFJ noise problem, I will go ahead with plan B.

tnx, Bill K9HXO
