[Elecraft] K3 as an antenna analyzer?

[Tom Hammond]

Kristinn:

That feature IS ALREADY AVAILABLE in the K3...!!!  Though not quite as easy
to access as one might want for 'daily' access, ALL of the KAT3 tuning values
CAN be viewed in the LCD display: (the last two sentences are the really
important ones here)

   KAT3 ATU mode; normally set to BYP or AUTO (you can alternate
   between these settings using the [ATU] switch). Modes L1-L8, C1-C8,
   and Ct are used to test KAT3 relays. Mode LCSET allows manual
   adjustment of L/C/net settings. When in this mode, tapping [ATU
   TUNE] shows the L & C value; C is changed with VFO A, L is changed
   with VFO B, and [ANT] toggles between Ca and Ct .
