I/ve been studying the spec of this rig and am surprised at the
degree of provision of facilities, including narrow CW filters at
the outset and the included automatic ATU.

But, assuming that one has space available for a shack, is it necessary
for everything to be so compact? For example, fiddley little buttons
and knobs?

My own shack (mainly a museum) covers a whole wall with 5 sets
of shelves and countless boxes beneath the tables, so compaction
is not an issue.
