KX3 Tuning noise with 2M module

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!
Gernot, DF5RF

Gernot,

did you activate the RXSHFT on 2 m? That should take care of it. Think
there's a remark on that in the KX3-2M manual, too.

Mark & Olli,
VFO NR reduced indeed the tuning noise. On a real antenna faintly
audible w/o PREAMP.
Great!
The RXSHFT has to be set to "NOR" according to the manual, which I did.
Thanks for the hints.
