[Elecraft] KAT500 - Blinking Mode Light

[Dick Dievendorff]

The ATU blinks the MODE LED when a tune has been started, but not enough RF
is arriving from the exciter to proceed. It's waiting for about 20 watts
from your exciter. If you want to cancel the tune, tap TUNE again.

Don't use both the K3 internal ATU and the KAT500 ATU together.  One or the
other should be bypassed.

Situation:  Tuner inline between K3s and known good dummy load.

1) Tuner off - K3s tunes 1:1 instantly
2) Tuner on in bypass - K3s tunes 1:1 instantly
3) Tuner on, and in Manual OR Auto Mode, tuner clicks and then Mode light
starts blinking.

All components in signal path obviously AND tested known good.

Any ideas where to start troubleshooting the malfunction?
