I'm sure there would have been a lesson on this at Hogwarts :)
Just to keep it on track I did wonder if perhaps in time there might be
a better option.
I know the Orion is just another old radio and not likely ever to
attract Collins type prices or reverence but perhaps there would be
enough of a market to warrant some 're-jigging'.
The board with the dragon also has the DSP's and ADC/DAC's plus some
other extraneous bit n pieces but from a hardware side is not much more
than a specialised computer with some peripherals. The software is of
course another story, it's been through various iterations and some
might say it's still not quite there, or will ever be now.
All that said I get to wondering if an open source replacement board
might be something to consider. Having seen what can be done with a lot
of the easily accessible and indeed free in some cases CAD/CAM tools
together with some community software development it would seem the
Orion might be an excellent candidate for a whole re-imagining of its
control, display and operation structure. I imagine a drop in
replacement cpu board with all the same connections and fittings but
with updated hardware and software. There's a lot of radio in an Orion
and 21st century processing scheme could probably make a lot more of it.

*Really simplified version.... O.K.?
Back in the good old days, electronic
components had wire leads. Now we have SMT or Surface Mount
Technology. So
now on Microprocessors and other LSI or Large Scale
Integration components.
There are tiny Pads or Lands on the bottom of the device. At
the factory
these components have tiny Balls of solder on each lead,
sometimes over 200
leads or pin connections could be on the device. In the new
technology, the
Chip is placed on the board by a very fast and precise
machine. The board
will then go through a multi-stage Oven which has a minimum
of Heat-up,
Solder or Bond and then the cool down stage. Going through
this oven on a
conveyor belt, the oven can be over 50 feet long. The
circuit board has no
holes for component leads to pass through. I have repaired
many video games
and other devices with a simple Paint Stripping Gun. It
takes a light hand
and a handheld infrared thermometer is a must so that you
don't cook the
board. It is very easy to do lots more harm to the device.
Repairs of the
Xbox 360 have financed several of my Boat Anchor Restoration
Projects. Try
goggling " The Red Ring of Death "*

just my two cents.
