It acts that way because it IS that way, if the K3 internal tuner is activated.

Presuming that both of you have the internal tuner in your K3s and no
external tuner, then, yes, what you're seeing is expected and normal.
Remember that the internal tuner provides a match to the receiver and
transmitter but cannot change the complex impedance that is present on
the feed line.

I do have an external tuner and the TXMON sampling unit is connected
between it and the amplifier.  I also have an internal tuner on the K3
and sometimes use it instead of the external tuner.  When I do, the P3
SWR meter is predictably reading much higher than the radio's SWR meter.

Deane,

I have discovered the same. It kind of acts like an SWR meter put *after* a 
tuner.

If I use a resonant antenna or transmit into my dummy load, I don’t get these 
squirrelly readings.

[Elecraft] K3 & Txmon Connection

2016-02-21 Thread Deane Walkington
I have recently installed  the Txmon and have seen some peculiar Power and
SWR readings on the P3 Display.  Power levels much higher than the K3 is set
to and SWR readings much higher (10:1) than the K3  indicates (typically
1.2:1).  I connected  the Coupler to the K3 ANT 1 socket via a short coax
patch cable.  What is the preferred method of connecting the Coupler - a UHF
male to male adaptor or a short length of coax?At present I have
disconnected the coupler from the radio and the P3.
