Yes, this is very clear and easy to follow. I will print those
schematics and put them in my folder.
Thanks.

Hi Jean-François,
Yes, in addition to putting back the W5 NB Bypass jumper, you
would need
to undo the rework that was required when you initially installed
the KNB2.
Have you done the other rework yet? It's shown in our updated
schematic
very clearly. The color code indicates which parts are to be
removed (red
with yellow background), and which parts are to be added, (blue
with purple
background).

Ooops.
I think I make a mistake ont his one. I read in the instruction that
if we need to remove the KNB2 later, we should put back the jumper
between pin 1 and 6 of J12. That's it.
I will revise all links you send me to properly build the KNB2
jumpers.
Remember that my jumpers are not as long as the connector inside the
K2, the reason for the red dot on each jumper.
II will modifiy this one right now...
Thanks for your remark !!

However, if you followed the instructions in Mark Dulecy's
original
article (hosted by W5BIG), then you may have used a 470 ohm
resistor in
error. Whereas your receiver will still function, the wrong
resistor value
results in a 5 db attenuator with a somewhat lower output impedance
than the
intended 150 ohms. It is possible that the resulting impedance
mismatch
could cause some intermodulation distortion in your receiver.
