It's a closed codec - you can't look at it, play with it, improve it
or
adjust it.

In fact, being patented, it's ILLEGAL to do any of that.

That's not strictly true. The whole point of a patent (from the Latin
'patere' - to reveal) is that an inventor discloses the workings of his
invention to the public in return for legal protection and the exclusive
right to prevent others from exploiting his invention commercially. It
does not prevent others from studying the invention and designing
improvements and even patenting those improvements if they meet the
required criteria. Of course, it will not be possible to exploit those
improvements without the permission of the holder of the original patent
(and vice versa). Whether an individual may build a patented device for
personal 'research' purposes will depend on the patent law in the
country where the patent was granted.


Which means it's not amateur radio.

I agree.

Hell, even the name is a registered trademark of Icom.
