[Milsurplus] Marine use of airborne radios

[AKLDGUY .]

Without doing any research whatsoever, and delving back into my memory,
I believe the Brit rationale was that positive ground resulted in less
corrosion of one of the terminals. Don't quote me on that and don't ask
which terminal. It's long forgotten.

As to why they eventually went to negative ground, the answer probably
lies in the proliferation of solid state car radios that started to appear
from
1960 onwards, mainly from Japan. If the Japanese were manufacturing
negative ground radios to suit the American market, there's quite an
incentive
to standardize.
