[Elecraft] KX3 Tuning noise with 2M module

[gt-i at gmx.net]

Hi folks,
received my 2M module this week. Assembly went fine, everything as 
described in the instructions.
TX works great, I can drive my PA with 1.5W.
RX is also quite sensitive. Worked 2 stations via TR > 400km, both were 
running less power than I did.
But: The tuning noise problem which I thought was solved (see my post 
over 1 year ago) is back alive.
It is extremely uncomfortable on VHF since 75% of all stations will be 
really weak in the first place - until you turn the antenna.
I'm not a big gun hence S&P is daily business.
I noticed that tuning with the VFO knob creates more noise than using 
the little "B" knob in OFFS mode.

Any ideas?
Thanks!
