. If the MFJ434 has AC coupling
(a capacitor between the AF Line output, you probably need to do nothing,
but if the MFJ434 is DC coupled, you will need to move the 5.6K resistor
from the K2 to inside the MFJ434.
The internal jumpers inside the MFJ434 should be contained in its
instructions.

that goes from the KIO2 to the KPA100 for continuity on pin 7.

Hi all: I got no response, so I thought I'd try to be a little
clearer. My
K2 was working fb, in all regards. Suddenly, it maxes out at about 14-15
watts, regardless of the power setting
on an 8 volt supply level).
If you have reasonable 'action' on your S-meter, the AGC circuits are
working.
Yes, I was the one suggesting the AGC Threshold optimization.

Lee,
I'm not in Seattle, but here near the other coast - BUT perhaps I can help
with your K2 calibration. Surf to my website http://w3fpr.qrprqdio.com or
the mirror at http://home.earthlink.net/~w3fpr and look at the article there
on K2 Dial Calibration.
Yes there is a possibility
will display this self-shielding effect if it is wound with perfectly even
spacing between the turns, but if the spacing is altered, more flux leakage
will exist and the inductance will change because the effective permeability
will be modified.

Bill,
As stated in the change documentation, the limiting factor is the power
output on 10 meters. Change it to a higher value and see what happens.

In setting up to use the K2/100 with my newly acquired AL-80A, I
found that the K2/100 power output
spacing, and that
may show up as an apparent change in 'inductance' on many meters because
they do measure inductance at a specific frequency. The best way I can
think of to prove or disprove it would be to measure the time constant in an
LR series circuit.

I started to do the 40meter tx power test when I set the
control for 2.0 watts, I get 2 watts out. When I set it for 5
watts, I get 5
with the KSB2 removed? Check both during
transmit and receive.

Still chasing the problem with the SSB board.
1. Rig works fine with the SSB option removed and jumpers reinstalled.
2. 8V is present on pin 10 P1.
3. C42 was left out by my mistake, installed.
4
situations do exist, and they are discussed here
too.

I am now confused by the existence of two different mod's with the same
goal.
It makes perfect sense to me that I should not be wasting Tx
energy on audio
frequencies as low as 20Hz. Beyond
- the voltage drop at load will be less - a 15 amp circuit
could use #14 wire, but I recommend using #12 (#10 for 20 amp) - of course
if the run from the breaker panel is short, the voltage drop will be small
even with the normally rated wire.

Perhaps I can help - do you want to tackle the KIO2 problem or the KSB2
problem first? They are 2 seaparate problems, so best not to mix them, it
will only cause confusion.

While working on the ki02 the k2 transmitted on its own and smoked
is working - it may be
related, but right now it is not informative.
We can do the detail de-bugging off-reflector and then you can report the
results after it is cured.

install that option because the VFO Range Selection
mechanism is modified although you may want to install the 2 headers, but I
see no gain in doing so because the K2 heat sink must be removed to install
the K60XV and adding the headers at that time is just another easy step.

, the power output may be
real, but the problem is the feedpoint impedance of the antenna and not the
K2.
Please povide ua with more information of what does and does not work, if we
are to offer more specific assistance.
