[Elecraft] KXAT1 - No RF Power on display

Kevin,

That behavior is typical of a bad solder connection somewhere.
I suggest removing the KXAT1 and installing the jumper - now what is the 
power output (you will have to use an external wattmeter) - operate it 
into a 50 ohm dummy load to eliminate the variables that may be 
introduced when operating into an antenna.

If the behavior continues when the back is put on, then the problem is 
on the main board - OTOH, if all works as normal, the problem is in the 
KXAT1.

With the back cover OFF, everything works better and get closer to 3 watts out.  When I put the back cover ON, it drops to 1 watt and the display stops showing the power out graph.
