[Elecraft] Building a KX1

[Don Wilhelm]

Ron,

Yes, you have the order of things correct.  If you are a very 
experienced builder and have great confidence in your ability to make 
things work the first time through without interim testing, then you can 
integrate the KX1 and the KXB3080, but I would not recommend that for 
the first time through.

If you do want to try it, you could build the KX1 without installing L7, 
C1, C26 and C27.
Then follow the KXB3080 instructions *only* through page 4.
At that point, you may test the KX1 on 40 and 20 meters.
Once that combination is aligned working well, start on page 5 of the 
KXB3080 manual and finish it.

One more note - do *not* add the KX1 Power Mod (included with the 
KXB3080 kit) unless your KX1 is not capable of producing 3.5 watts with 
a 13.8 volt power supply (3 watts with a 12 volt supply).  Most of the 
KX1s with the newer PA transistor do not need the power mod, and running 
much over 4 watts for a period of time can damage the components in the 
PA output circuit.

73,
Don W3FPR
