[Elecraft] K3 vs RigExperts SWR meter issue

[Jeff Cochrane - VK4BOF]

Hi Alexander,
I see this a lot with my K3.
The truth is that the KAT3 is never really out of circuit.
The trick is to enable the KAT3 (Hold ATU Tune), use it to show a low VSWR to the rigs finals, then disable it (Hold ATU TUNE) again.
You will then find that the VSWR will presented to the rig will be correct as per the analyser.
I don't why the KAT3 still appears to be in circuit when supposedly switched out but at least there is a workaround.

  Hello:

  I just bought an AA-54 RigExperts analyzer.  I am tuning a Buddipole
  which I use with my K3 (25+ countries and counting).

  The RigExpert says my SWR is 1:2.5 at 14.200Mhz.  I also scan the SWR
  curve with it and I see that I am 1:3 or lower a couple of 100hz
  around the 14.200 center frequency.

  I hook my feedline up to my K3, put the KAT3 on bypass, set VFOA to
  14.205Mhz and ask if the frequency is in use.  I immediately see "HI
  SWR" on it.  I can definitely use the KAT3 to tune out any reactance
  and my SWR/RF look reasonable (I hit 100on the RF Scale and the SWR
  meter doesn't go above 2).

  What am I missing here?  I am trying to compare the SWR meter on the
  K3 against what the RigExperts claims as a learning exercise (1.5
  month old ham here).
