Though radio people seem to appear sometimes:
Bob Padula OAM (also an engineer) - http://bpadula.tripod.com/autobiography/id54.html  for services to shortwave listening
Arthur Cushen MBE - https://nfb.org/images/nfb/publications/bm/bm98/bm980411.htm

I think you first have to get nominated by someone.

I think you first have to get nominated by someone.

True.  Radio people (eg at least some of the above) have organised themselves into clubs for over 100 years so there's potential for others to know of their achievements and nominate them.

There were a lot of computer & CB radio clubs in the '70s and '80s but most seem to have died.   

Judging from old electronics magazines there were hardly ever any high-profile electronics hobbyist clubs - possibly until the advent of hackerspaces in recent times.

I don't recall reading about a single one in any of the Oz mags since I started reading them in the late 70's.
There were computer clubs, but that's all I can remember.
