This next section skips over a few other sections primarily so that we can get the analog to digital

this buffer and the VXO so that we can test the VXO that was just finished. The RF phasing section
contains parts that are band specific.
The RF phase splitter will not be aligned until much later in the receiver section when alignment is
performed to null out the opposite sideband.
Install the parts in this section in the following order:
