[Elecraft] KPA100 option almost done...

[Steve Kallal]

Well after about a month, I almost have my KPA100 option finished for the
K2. I didn't accurately time the hours, but I think it is in the 25 hour
region. This is the first serious kit I've built in years and the most
serious ever. I had only one mistake to correct. U7, the dual op amp, was
reversed. Once that got replaced, the amp came to life.
 
I have a couple of issues left, minor ones.
 
1. The power does seem to vary a little bit on key down, nothing major, but
a few percent before the power level settles. The TUNE function indicates
1.5:1 SWR into a dummy load. Perhaps I need to go back and retweak the SWR
setting.
 
2. The speaker sounds like the cone is bad. I ordered a bunch of parts from
Elecraft, but the speaker slipped my mind. I will need to remove the shield
if the speaker gets replaced. Does the adhesive comes loose easily?
 
Thanks for all help from this reflector!
