Dave,
Tnx for the tip. In one K3 the 400 stayed at 0, and the 200 went from -.89
to -.84. In the other K3 the 500 went from -.75 to -.88 and the 200 went
from -.94 to -.96.

Why use the S-Meter for this? Depending on where you are in that S-Unit
that can make you miss the center. What you need is a relative dB
measurement. Turns out that the only piece of test equipment that you
need is a K3.
Center the signal in the passband. Then hit disp and use VFO to get to

Same here.
I have to overload a little ALC and CMP and it solves almost all the
problem, but it continues.
Before the k3 i owned an Icom 7700 and with the correct ALC and CMP it
had a very stable SSB Power.
I am sure it can be solved with a firmware update.

Hi Maury,
Some things spring to mind:
- Does this problem also occur in TEST mode (press and hold the MODE^ button)?
- If not, it may be RF coming back to the rig. Is the rig grounded?

which the built-in ATU had problems matchi
There is a lot of difference between exposing the radio, i.e. the finished

Juha this "problem" is an old one. Some time back the K3 had poor ALC
which allowed for overshoot on peaks, the firmware was altered to soften
the ALC control with the results you (and the rest of us) experience.

I have K3 #2100. On CW power is very stable, but not on SSB. There is some

Being in the semiconductor business and having sat by a anti-static

about long-term damage. However, if you want to treat your rig like a

Inject a clean signal to the K3, around S5 - S7 in level, go into the

other side until it again drops one S point. Set the offset to the

A proper grounding mat costs a fraction of the price of a transceiver,

Some of the anti-static bags that Elecraft use are the pink ones. Those
are non-conducting and get their anti-static properties by not
generating static, rather than dissipating it. They would be useless as
an anti-static mat.
