setting KPA 100 page 48 problem

Good morning all ,

Zero adjustment of SWR bridge (C1) page 48

as you see on the video , I set the K2 to 5Watts

https://we.tl/t-MOz5AX1v3l

I managed to adjust the SWR the K2 announces my power at 0.1 Watts !!

the consumption goes from 0.32 Amps in Rx, in Tune mode 0.5 amps

I should have 5 Watts

Thank you for your help

# K2 7369 - kpa 100 in progress

Re: setting KPA 100 page 48 problem

Christophe,

When doing the C1 adjustment, look for the lowest voltage measured at U5
pin 1 (TP4) -do not look at the SWR at that point, but look for the
lowest voltage on your DMM.

Once you have achieved that null, then you will adjust the R26 and R27
potentiometers for the power indication and SWR indication. Do it as
specified in the manual.

Use 10 watts of power rather than 5 for a better indication.
After you have done the calibration at 10 watts, do a TUNE/DISPLAY (hold
both buttons together) with the power set a 80 watts or so, and fine
tune the adjustment of R26 to make the K2 power indication match your
external wattmeter.
Do not bother to adjust R27 again unless you had to move R26 a
significant amount (if you had to move R27 a lot, you may have another
problem to resolve).

Re: setting KPA 100 page 48 problem

In reply to this post by Christophe aufacf

Christophe,

I forgot to mention,
Before attempting to adjust the C1 null, first pre-set R26 and R27 to
43k ohms. Measure R26 from U5 pin 5 to ground and R27 at U5 pin 3 to
ground.

Then go through the nulling process followed by the power setting
process that I outlined in my prior email.

Re: setting KPA 100 page 48 problem

hello Don, hello everyone,

this morning I tested the K2 on my own.

the consumption (ampere) of K2 gave me part of the solution

the K2 alone in transmission consumes 0.5 amp on 40M then on the other
2 amp bands with a setting at 5Watts

so I have no broadcast on 40M only, we can hear the relays switch ...

after I admit being a bit lost to know where to start

I will review the soldering of relays K1, K12, K14 in case ...

could you give me advice since you know the K2 very well

Thanks in advance Don

Re: setting KPA 100 page 48 problem

Christophe,

The most common cause of a 40 meter only failure in the K2 is an
incorrect setting of the D19 secondary menu parameter.

If you have the K60XV option installed, or if you installed the "Rework
Eliminators" when you built the K2, you must set D19 to "y".

If you do not have either the K60XV or the Rework Eliminators, then the
D19 parameter must be set to "n".

If the above is not applicable, you may have a problem in the 40 meter
bandpass filter. Check the capacitors in that bandpass filter - C5 and
C7 = 100pF, C4 and C8 = 820pF, C6 = 4.7pF.
Also check the VFO frequency when the K2 is set to 7100kHz, it should be
close to 12,015kHz.

Re: setting KPA 100 page 48 problem

good evening Don,

I checked the values and solders of the capacitors mentioned
they are ok

on the other hand remind me of the procedure to check the frequency of
the VFO so as to find 12,015 KHZ pages in the assembly manual

Thanks again for your help

Re: setting KPA 100 page 48 problem

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.

Re: setting KPA 100 page 48 problem

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.

Re: setting KPA 100 page 48 problem

Christophe,

OK, the first thing you need to do is check the value (and soldering) of
C71 - it should be 120pF (marked 121).

If that is correct, you need to check continuity through relays K13, K14
and K15. The schematic shows the relays in their not-set position. K13
and K15 must be not-set, and relay K14 must be set (opposite the
position shown in the schematic).
Turn the K2 on and set the band to 40 meters, then turn it off (the
relays are latching) and do the continuity test with your ohmmeter.

Re: setting KPA 100 page 48 problem

In reply to this post by Christophe aufacf

Christophe,

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

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

Re: setting KPA 100 page 48 problem

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.

73,
Don W3FPR

Re: setting KPA 100 page 48 problem

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

73 , Cris F8ACF Happy Easter

Re: setting KPA 100 page 48 problem

hello Don,

the measures find
3.600 => 18161
7.100 => 18163
10.120 => 15034
14.100 => 19014
18.110 => 23024
21.100 => 16185
24.930 => 20016
28.200 => 23285
I put a link to a video : https://we.tl/t-rFR61aZsYH

look what happens when I go from 20 to 30M with HI CUR power for a
fraction of a second, 14 W instead of 5W

if I reconcile again the step of HICUR and I have my 5W, surprising! ...

may be related to my breakdown I think?

thanks again for your help

Re: setting KPA 100 page 48 problem

In reply to this post by Christophe aufacf

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.
