[Elecraft] K3 "No ATU" and 12w max

[cx7tt at 4email.net]

This morning I turned on K3 #250 and got a ERR AT3 msg which was strange 
as when I shut down the radio yesterday, everything was fine. I rarely 
use the ATU as I have a Steppir beam and inverted L which I run thru an 
external tuner.
I started troubleshooting and went thru the following sequences:
After seeing the ERR AT3, I check the config, it was in BYP.
ATU Tune- No ATU
Config-ATU to auto
ATU Tune-No ATU
Power-OFF/ON
No msg this time
ATU tune- ERR LPF
ATU tune-ERR IO3
ATU tune-ERR IF1
ATU tune-ERR xv3
ATU tune-AT3
ATU tune-ERR PA1
ATU tine- ERR BP3

Xmit/Tune- 12 w max (KPA100 installed)
SWR shows 1.8 on K3 display, LP Pan shows 10.6w and SWR of 1.15 (on 
exact Steppir freq of 14.050)
Same with ATU in BYP or Auto
KPA3 in nor

Any ideas/suggestions
