One of the bedrock 'values' of the Amateur Radio Service is
experimentation and "advancement of the radio art", yet FCC has
historically dragged its feet in allowing us the leeway to try
unorthodox modulation schemes, new transmission modes, etc. (As an
example, Canadian amateurs had AX.25 up and running for almost a
decade before FCC would allow W/K guys to play in that mode.)

Interesting example because in some aspects the US is more liberal
than a lot of other countries with regard to the amateur service.

The only modulation scheme that I had any contact with the "delaying
factor" was spread spectrum. The powers-that-were were very reluctant
to permit this in the amateur service because of the history of spread
spectrum - as you well know it was developed for the military to
frustrate transmitter location and interception of traffic, two "gotta
haves" in FCC amateur radio enforcement (whether they are used or not
is a different story). When the equipment to do so was finally
acquired and put into service, the mode was released for general use.
That's real life in the trenches....
