[Elecraft] KAT500 Tune Memory and Power Failure Restart

[Phil Hystad]

Regarding my questions below...

I was reminded that the KAT500 utility has a save feature which I did dutifully use after I set all my memory tune spots.

I have now restored my saved configurations.

But, I would still like to know if this is the normal behavior -- that is, a loss of power means loss of memory meaning that the memory for the KAT500 is totally volatile??  I am pretty sure I have unplugged the equipment at times and have not lost anything so I am still confused of what is normal behavior on a power loss.

I lost power ever so briefly, about 2 seconds maybe, during dinner at 5:45 PM.  But, enough to cause restart of all the equipment except for laptop and other battery operated things and battery backup saved iMac-24 from a restart.

Doing a retune took the longest time of clicking relays and SWR racing all over the place as if the match was being searched from minus infinity.

I was not in the room when this happened so I am assuming that power on startup was a race and I am thinking that the KAT500 might be first but I don’t know.
