[Elecraft] K3 KAT3 strange behaviour

[Gary Gregory]

G'Day all.

Just now, using a double extended zepp I find it tunes all bands except 20M
consistently but for a couple of weeks it has been fine.

The KAT3 will tune to 1.1:1 BUT the swr meter fluctuates to 3:1 but does*not
* generate HI SWR on the display.

All other bands this behavior does not occur.

Press and hold tune at 5W and up to 100W the swr shows stable. Without the
KAT3 the zepp is 1.4:1 and reads stable.

SSB Tx however produces this fluctuating swr reading which reaches as high
as 3:1

Scratching my head here as all other bands 80 thru 10M this swr problem does
not appear.

It started during a qso and the other station reported a jump in signal
strength from S2 to S9 on 20M

Any clues from the group would be most helpful.
