Thank you for answer,
The spurious signals are not only visible on P3 but perfectly audible in the
speaker.
I have also tried turning P3 off and unplug it but the signals are always
present and audible.

That sounds like a P3 cable problem. There have been reports of
faulty BNC cables supplied in a batch that was bad from the supplier.
Try contacting Elecraft and describe the problem to them.
Also while you are waiting to call Elecraft over the week-end, make
sure that ALL of the cable routing is as it was before the
installation. That covers any existing cables you may have moved
around.
Good luck,

Today I installed the module K144XV. It all works ok but I noticed several
spurious signals received, in particular each 12.5 kHz at a level
of around -140 dbm indicated on P3, plus some pretty strong signals such as
at 144.4165 to S7 and others.
Obviously signals are present with the antenna disconnected and with a 50
Ohm load on the antenna connector.
I exclude the origin from the outside of the transceiver, I disconnected
all possible noise sources such as switching power supplies and similar.
It 's normal or there may be a problem? Any suggestions?
