Hi there!
I assembled my KXPA100 (with ATU) recently, serial number 0595.
Unfortunately, it isn't working. The link to the KX3 works great
(rather slick, everything was instantly recognized), but the KXPA100 is
not making any antenna connection cleanly. KX3 is properly configured
to link with
Josh,
Unfortunately, I'm not familiar enough with the KXPA100 to know if,
when bypassing the unit internally, there is DC continuity between the
input and output. If there is (I suspect so), you should be able to
measure between them with a regular ohm meter. While not 100%
definitive,
The first thing you need to do is to use the same SWR-meter both at the tower
and at you're K3.
When measurering close to the K3 and if it is a big difference between you're
SWR meter and the K3, the K3 is probably indicating the wrong SWR, or the K3
tuner is coupled in making the SWR to be
My experience with this is that if one is seeing an SWR 2.5 -3 it
usually means either the braid or center conductor isn't connected.
I'd redo the connectors.
You don't say how the measurements were made at the tower. But I'm
guessing it was done with another short piece of coax. Thus
Is it possible to set the KXAT3 to activate per band? If so, can someone
point me to where that is in the manual? I cannot seem to find it.
Thanks,

Mark,
Any transmission line will have an impedance transformation unless it is
terminated in its characteristic impedance.
The other factor may be that you have some common mode current on the
coax shield - that can skew SWR readings.

Hi,
Martin makes an important point!
The VSWR indicated on the K3 is measured between tuner and PA. The tuner
does not influence the VSWR on the feeder.

The tablet sized E Series 20 case seen at the url below should do nicely for

SWR meters don't generally tell you the SWR on the line they're connected
to, except in special cases. That's independent of the line losses
discussion.
If the SWR on the line is other than 1:1 and you move the meter along the
line, the indicated SWR will change but the actual SWR on the

Unless your antenna is exactly the same impedance as your feedline at the
desired frequency (pretty unlikely) then the feedline is going to
transform the antenna impedance based on distance from the antenna. The
exception to this is feedline lengths that are perfect multiples of a half

If I take a lossless 50-ohm line and terminate it in 100 ohm and measure the

Hi All,
I have an opportunity to pickup a Timewave 599 audio filter to use with
my K2.
From what I understand, audio filters like the Timewave units are really
good at reducing cyclical noises, but not simply to reduce general
noise-floor levels.
I'm wondering if it would be a waste of money for

Josh,
Yes, DC measurements can be confusing - it all depends on the input and
output networks.
Rather than attempting to make that measurement at DC, connect your
antenna analyzer to the RF IN jack and a dummy load to the ANT jack.

Hi,
It would be great if the KX3 could retain the mic gain setting per mode.
When using the Elecraft mic, mic setting is quite different value between
SSB and FM mode by example.
Especially now with the 2m module, FM could be used now more often (at least
for many) so always adjusting the

Looking at the owner's manual, page 41, there is a simplified

considerations, but I would suspect that's the way it is. Until someone
