[Elecraft] KX1 and KXB3080 L3 Mod

[Chuck Gehring]

My KXB3080 L3 Modification

The L3 Mod is complete and working fine.

Before I installed the R11, R30 resistors, my KX1 power out with 13.7 VDC
was:

80m  	3.1 watts
40m  	2.9 watts
30m  	3.4 watts
20m  	2.6 watts

With the R11, R30 resistors installed and 13.7 VDC power out was:

80m  	3.7 watts
40m  	3.6 watts
30m  	4.2 watts
20m  	3.3 watts

I just completed the L3 modification and my KX1 power out is:

80m  	3.9 watts
40m  	3.7 watts
30m  	4.3 watts
20m  	3.4 watts

Power out was measured with into a DL1 (Dummy Load) and measured with a DMM.
Granted the power out from beginning to end was not really that significant
in the big scheme of things. It was simply an opportunity to burn some
solder and learn a little more about my radios.

I really do appreciate everything Wayne, Eric, Gary Surrency and everyone
else at Elecraft continues to do for Elecraft builders, the general Ham
population and myself.

Three years ago I would have never dreamed of building a radio.  Two years
ago when I built my KX1, I prayed that I got everything right the first
time, because I didn't think I would be able to find and fix any problems.
Just thinking about winding Toroids put me into a sweat.  Now it seems like
one of the best things about being a ham is the tweaking, and fixing.

Thank you so very much
