Just a dumb question:
How do you insert the external SWR meter on the same node as the K3
internal SWR bridge?
I don't find an easy solution for my own comparisons.

Rudolf,
There is no way to do that external to the K3. It would only be
possible if one were to dig into the hardware and insert the external
wattmeter into the signal path between the KPA3 and the KAT3.
Unfortunately, that would require cutting traces inside the K3.

Don,
Thank you for the explanations;
the difference between external SWR and
K3 SWR without ATU should be less then
the differences announced ?

Mike, I see the same thing. My Autek says my antenna is 2.5:1, the K3
(#476) says 1.2:1 at the same frequency (numbers mentioned were on
40M).
My Palstar SWR meter pretty much agrees with the Autek.

Just for the record, I have excellent agreement between an external
(MFJ-949E) SWR/Wattmeter and the indication on the K3, both at excellent SWR
and poor ones such as those offered by my G5RVs when the external tuner is
bypassed. Poor agreement here should not be considered normal.

Brett, this is something I would love to see in all rigs and amplifiers, but
then I'm prejudiced;-)

One thing I think would be really slick is to see a path in which
someone can insert a watt meter such as the LP-100 into the chain
between the output and the antenna tuner where
This thread came at the right time. I have just finished
re-calibrating my LP-100A. I did this after having used the unit
for 6 months, however the calibration was very close to the
original settings.
Then I thought that I would check my K3 SWR indication.
The results are not as good as I would
However, the Gap SWR is around the
2.3:1 range when the K3 (or PW-1 tuner) reads about 1.5:1 or less. I then
realized it was showing me the real SWR, not the tuned SWR.
I think I am correct in this assumption.
John, your understanding is correct unless the K3 ATU is in bypass mode
which it was

Isn't the LP100A giving you the actual SWR, not the tuned SWR since the
LP100A is getting current samples from the feedline to the antenna and is
independent of the K3 tuner. The K3 tuner
I have been working on antennas today and have a puzzle. I am finding that
the K3 SWR indications are unbelievable generous.
With my 40M inverted V fed with RG8X (50 ohm) coax I see that the K3 seems
generous in the SWR indication on tune with ATU bypassed. I have noticed a
slight change in SWR
Mike,
I have to accept your observations, but must ask - have you calibrated
the K3 wattmeter? Neglecting to do that can cause the SWR readings to
be off by a fair amount.
That being said, consider the purpose of the K3 having an SWR indication
at all - that is to determine the minimum SWR
I noticed the same thing. My factory-assembled K3 is reading 1.0 SWR while
my LP-100A and tuner both agree on about 1.4-1.5.
