[Elecraft] KAT3 question

[Rick Dettinger]

I have just installed the KAT3 and it seems to be working, however, i  
can only get a SWR of 4.0 on the K3 on my 40M end fed antenna.  I know  
the SWR with this antenna is very high, but I can get the SWR down to  
2.5 with my K2 ATU.  The K2 is using ALT tune to get there taking a  
long time.  I can understand that this could be a matter of chance,  
since the tuners use discrete components, rather than adjustable  
ones.  I don't find much info on the KAT3 in the Installation  
Instructions or the K3 Owner's Manual.  Sheet 3 of the KAT3  
Installation Manual, Introduction, says "Complete details for using  
the KAT3 are included in the KXV3 Owner's manual."  I can't find a  
KXV3 Owner's Manual on the Elecraft site, only the Installation  
Instructions and I don't have a KXV3.  Do I need a KXV3 to use my  
KAT3?  Does the KAT3 have the equivalent of ALT tune on the K2?  The  
KAT3 seems to give up after a few seconds, while the K2 tries real  
hard to get a good match.  I can prune my end fed antenna but I may be  
missing something here and would like to know.

Thanks and 73
