[Elecraft] [K2] RE: KAT100 error Fixed Part One

[W4HDM]

 Recap:KAT100 Tuner was going through the motions of tuning showing an SWR
of 1.0-1 but K2 showing a high SWR. Reduced power on TX on all bands. SWR
scale lights on the KAT100 not lighting during tune or TX.

 

I replaced D1 and D2 diodes on the KAT100, per  Skip,  WB4DAD's suggestion.
This has the KAT100 tuning and showing lights operating as they should. I
suspect a near lightning strike or power surge caused these to go bad?

 

PART 2: The only issue I see now is that the tuner always reverts to ANT 1
on power up. If I shut down while set to ANT2, when I power up it will show
2 for a second then go to 1. Anyone had this problem?

 

Thanks again to WB4DAD and his friend that passed this info to him.

 

Also, I would like to thank Don, W3FPR for his help. He has helped me on
several problems and gets my vote into the Elecraft Hall of Fame. I suspect
he would have solved this as well if not for my post being rejected from the
site.

 

Now to put it all back together!

 

Note: I ordered 10 of these diodes from an internet source, but being
impatient I found them at FRY's.  Same thing with the 40 pin firmware
socket. So if anyone needs diodes or 20 pin sockets, feel free to contact me
off list.
