Hi all: This afternoon I received the KPA100UPKT package in the mail to upgrade my KPA100 to the latest version, Rev D. MY KPA100 is a fairly recent one so some of the upgrade steps did not apply. Keep in mind that this Upgrade package includes all changes since the KPA100 was introduced.
First... There are a couple of typos that have not yet been picked up in the errata sheet. (Elecraft has been notified of these typos.) The Parts List indicates that R4 and R33 are 1/2 watt resistors, the text calls them 1/4 watt resistors, and that is what was provided. On page 6 of the instructions, the 4th step states "Remove capacitor C16..." That should read "Remove capacitor C64..." The upgrade went quickly, but I really have become spoiled by having the Hakko 808 desoldering tool. Removal of components was painless and left clean through holes. I don't have any quantitative data on performance changes, but it seems more stable than before when using the KAT100 tuner. Also, the output on the higher bands (12 and 10 meters) in improved. I can now get 110-120 watts output with R26 properly adjusted. Before I could only get ~100 watts out. 73, Ken Wagner K3IU Portsmouth, RI K2/100 #5413 (my 10th) _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
