[Elecraft] K1 Transmitter problem

[Dennis Rayfield]

I'm building a K1 and have everything finished and am at the stage for transmitter alignment and test.  I use the out menu to set the output to 3 watts, but when I put it into tune mode it immediately shows P0.1 on the display and there is no power out.  When I take it out of tune and go back to the out menu, that still shows 3 watts.

Any suggestions where I should start with this?  

Thanks for any suggestions.
