[Elecraft] KAT500: Tuning on 6m

[KD7YZ Bob]

Howdy K3' people:

There is an 8-element yagi connected to the KAT500 for the K3 internal
6m selected 6m antenna.

I set KAT500 default antenna for 6m to Ant2.

On the KAT500 I can press 'TUNE' then tap K3 "XMIT" and the KAT500 will
usually settle on or about 1.1:1 .

Then when I .run a WSJT, Data, QSO, if the KAT500 is left in "AUTO",
re-tuning will often take occupy 10 or more seconds of the time before
the KAT500 finds a place it likes. Often the SWR is then in the RED or
worse, FAULT. Not very often on FAULT however.

Mostly what I see are SWR's around 2:1 .  (KAT500 in AUTO .

If I put KAT500 in BYP,  the K3 often shows SWR's of 2 to 3.

If left in AUTO, the mismatch is apparent in received audio.

Without the KAT500, the antenna itself exhibits a 1.3 SWR consistently .

The constant re-tuning or irregular attenuation due to mismatch form
KAT500 is annoying. On a weak-signal QSOit means the difference from
making the QSO or not decoding.
