[Elecraft] KPA100

[Fred Jensen]

Hi all,

I was experiencing the 40m parasitic and so I made the positioning mod 
on RFC10 as shown on N0SS' web site.  It was really easy.  I didn't 
touch anything else (I know, that's what they all say, but honest, I 
didn't ... at least I don't think I did :-) ).  Now, the KPA100 
indicates "Hi SWR" and apparently throttles back the power to virtually 
nothing.  Same thing happens if I reduce the requested power below 10W. 
  It's been sitting idle for quite awhile awaiting some time to look at 
it, which came today.

I checked D16 and D17 with the DMM.  On the 2000 KOhm range, they read 
105 and 99 respectively in the forward direction and infinity in the 
reverse.  They read infinity in both directions on any other resistance 
range.

1.  Can I even check them this way?  My DMM is a cheap little pocket 
CEN-TECH P30756 that I won at a hamfest.  It has a 9V battery in it.

2.  Any ideas for what else I should check before I ship it to someone 
for "real repair?"

KEVIN: ECN will be on the TS-850 this afternoon, K2 is on the operating 
table.
