[Elecraft] KX-1 output problem

[Ken Kirkley]

Hey John:
I had a similar problem with my KX1. It ended up being a bad solder 
joint on a resistor pack. I cannot remember which one, but if you look 
at the schematic
you will be able to locate it. After applying a little heat to the joint 
all was OK. Hope this helps in some way.

When I finished the basic KX-1, I put it on an uncalibrated QRP wattmeter and it read about 2 watts, so I thought I was in the ballpark. Now, assuming that my original 2 watt reading is really 0.9, I find that the output is the same both with and without the ATU, so the problem must be in the transmitter and not the ATU.

I've checked the continuity for all the toroids and T1, as well and recounting the turns and lead placement.  The output control is fully clockwise and the output is being fed into a 50 ohm dummy load.
