[Martin, AA6E]

The main problem in software engineering is figuring out what is this
program supposed to do, and how do we verify it?

The Orion (only to pick one example) has an extremely complicated
interface to the user (possible combinations of parameters and
sequencing), which is probably not written down or specified anywhere.
 This is in contrast to the RF specs, which are fairly easy to state
and measure.

Most software design is seat of the pants - you'll know it when you
see it, etc.  Formal definition of software specs and correctness is
something you see at NASA and Boeing (well, sometimes!).

I am afraid that K4TAX and others are right that this is the way of
the future.   The boat anchors didn't have such great performance, but
at least they were predictable, and you could figure out most problems
from a schematic.  (I keep a TS-520S in the closet, in case of EMP
attack or other digital meltdown.)
