Lid  
This sense of lid is still common today in Amateur ("Ham") Radio (in the United States, at least), usually as "they're a lid", meaning "they're being a rude or unobservant person."
It doesn't refer to new operators, usually, as much as someone who is willfully ignoring convention.
We can't really see how this originates from any meaning of lid; the most plausible origin to me seems the phrase "put a lid on", because as an operator, a lid "silences" others or "puts a crimp" in their operating.
