[Elecraft] KAT3 - Antenna tuned or not?

[John W2XS]

I have often thought about adding an additional BNC connector to my K2 and
KAT2 to insert an external meter like the W1 in between the rig output and
the antenna tuner input. A short jumper would be needed if the meter is
disconnected. The "aux RF" is one BNC connection and another could be wired
to the tuner's input. 

The meter would then show the actual SWR that the rig sees after matching. I
like the continuous display of SWR and power output but, as has been pointed
out here, it does not make sense to monitor the SWR after the tuner.

I try and keep the coax cable as short as possible between the rig and the
balun because of the high SWR on that line. Most of the time I use a
male-to-male BNC adaptor between the rig's output BNC and the balun.

The external SWR meter is not affected by the KAT3 because it is between the
KAT3 and the non-resonant load.
