Since I bought the 100 watt Power Amplifier option, we have to install the shield for it. You also have to move the frame stiffener that we used on the top cover install to the chassis for this option.
Here is the bottom of the main RF board. There are a few stand offs that get installed on the bottom where the covers will attach which you can see in the picture.
After that is done, the bottom stand and feet get attached to the front half of the bottom cover.
The Noise Blanker board is installed
Insert the battery
I bought the General RX
board option, so now that board is installed.
Attach the front half of the bottom cover and put some adhesive thermal transfer pads over the low power amplifier transistors. These will contact the other part of the bottom cover, making it act as a heat sink.
Now the bottom cover is attached. Note the difference in the screws in the middle that attach to the LPAs
Finally, the 10 watt Elecraft K3 is assembled. If you purchased the 10 watt version, you would just finish the build by putting some plates across the back, but this the 100 watt version so I'll install the fans later.
Now it's time to do the calibration and testing before installing the 100 watt PA.
