Enclosure Construction

       

This is another shot, showing the 3-dimensional construction of the RF-enclosure. The entire enclosure is actually "upside down" at this point. Eventually, the RF chain is "underneath" the floor.

The narrow sections were originally where I planned to put Pi attenuator pads. My original thought was to build in 1dB, 3dB, 6dB, and 20dB, and possibly an extra 1dB attenuator. Once I got the basic RF chain working, and started getting used to how the Spectrum Analyzer actually operates, I realized that a 5dB, two 10dB and one 20dB attenuator would be infinitely more practical (the basic idea is to calibrate the SA with your scope to get 10dB per vertical division).
