Christophe,
K13 and K15 should have continuity between pins 2 and 3 also pins 8 and 9
You should also determine that there is an open between pins 3 and 4
also 7 and 8.
K14 should have continuity between pins 3 and 4 also 7 and 8. It should
b open between pins 2 and 3 also between pins 8 and 9.
For comparison with the VFO chart on the schematic key, use the low end
of each band - 3500, 7000, 10,000, 14,000, 18,000, 21000, 24,890, and
28,000 kHz.

hello Don,
continuity measurements from C71 ==> K14 PIN 3 & 4
K12 PIN 7 & 8; K15 PIN 2
for measuring band frequencies
80M, 30M, 20M; 17; 12 and 10M
on 3600, 10.140, 14.100, 18.100, 21.100, 28.100
will that be correct?
as I did on 40M

Good evening to you as well Christophe,
C71 is properly 82pF, thanks for checking.
That likely means you have a relay problem with either K13, K14 or K15.
You may have a similar problem on bands other than 40m.
You should also check the VFO frequencies on each of the other bands.
Set the K2 to the lower edge of each band, then measure and compare with
the VFO Freq. chart on the K2 Schematic Key page.
A list of the VFO frequencies that are far away from where they should
be will give me the information needed to point to the relay at fault.
Although you may find that with the continuity check.

good evening Don,
visually C71 blue capacitor "82J" so correct for registration, I think?
for C71 in conjunction with K13 pin 7 and K14 pin 4 on the diagram
I will give you the continuities on the relays tomorrow after having
started the K2 on 40M then having turned it off
thanks again for your great help
good night, here it is 22H local

Christophe,
I made a mistake on the value of C71. With no K60XV installed, the
proper value is 82pF (marked either '82' or 820').

hello don
I forgot to answer you no K60XV, no rework that I do not know this
option, I have the NB option provided for purchase
for the parameter D19 = N
thank you in advance

Christophe,
You have not yet answered 2 important questions which relate to your 40
meter operation.
1) Do you have the K60XV option installed (or do you have the Rework
Eliminators installed)?
2) What is your setting of the secondary menu D19 parameter?
The answers to those 2 questions is critical to what to do next in
troubleshooting your problem.

hello don
the frequency to find with CAL FACT 18.159 kHz
thank you in advance for your good advice

Christophe,
Tune the K2 to 7100kHz
Then plug the internal counter probe into TP1 and the P6 header on the
Control Board.
Enter the menu to CAL FCTR and hold EDIT
The frequency will be seen in the K2 display.
You could alternately use an external frequency counter to read the
frequency at TP1.
