[Elecraft] KX-1 Q6 and Power Questions

[Brian Wruble]

Hi All:

I just completed KX-1 #414.  Great fun, and everything seems to work, but I
have 2 questions:

1.  The chassis screw that goes through the shoulder washer and secures Q6
is very sensitive to being screwed in too far.  The Q6 tab shorts to ground
with the screw still extremely loose, almost falling out.  The positioning
of the thermal pad looks exactly right, but it acts like a little bit of
additional screw tightness is somehow causing the tab to get past the
thermal pad to the metal case.  I simply cannot figure out how this is
happening.  I am concerned that a little inadvertant hand pressure on the
case while operating might cause a catastrophic short.  Any suggestions?

I used my DMM and the DL1 dummy load to measure power on the 3 bands (I have
the 30M module installed).  I get

20M 2.50W
30M 3.38W
40M 3.26W

Are these ok, or can I do something to get closer to 4Watts?  I do not yet
have the antenna tuner installed, that's next.

Tnx.  73 de Brian W3BW
