[Elecraft] Meaning of KAT500 flashing Auto light

[ANDY NEHAN]

I am having some problems with my understanding of the KAT500.

I have a K3 and an ACOM1000 linear. On 40m when I operate data modes or AM (purely for testing purposes) all is well the units work well together. I can happily run up to 400 watts and as is well. My 40m OCFD has an SWR of about 1.2:1.

But when I operate SSB things go "odd". For no apparent reason the KAT500 starts to retune part way through and over and enters a fault condition (on the same frequency as I was using for data - so there is no frequency change involved) and the Auto button flashes. Now I have looked in the manual and cant find the meaning of the flashing Auto LED.

Can someone advise me please. I know its me but I am puzzled.
