K2: KAT 100 question

[jferg977]

There have been a series of repairs to my KPA100 and the KAT100. I have  
realigned the KAT100 as per the manual.  It brings the SWR down to 1:1 on  40 and
20 meters and 1.2:1 on 80.  But on 17 meters, I'm getting 2.3:1  where I used
to get more like 1.1:1.  Do I need to redo the alignment or is  there a chance
that in one of the recent EDS events, a part other than the  1N5711's has
been invisibly fried?  The antenna system is a simple 23 foot  shakespeare whip
with an additional 8 feet of lead-in.  Grounding is the  saltwater harbor I'm
in.
 
I'm assuming that the SWR issue, whatever it might be is either antenna or  
tuner and not a result of some issue in the K2 itself.
 
I've looked at all the connections and they seem sound.  Ideas?

John,

The relays and inductors in the KAT100 are pretty hardy, so unless you
got a direct hit, I would not suspect them.  I would do the 'relay
click' test from the menu to be certain all the relays are operating.  
After that I would suspect something has changed in your antenna and/or
feedline - salt water corrosion perhaps?  The feedline could have become
damaged with a lightning surge.  Be certain all the connectors are clean
and tight.
