[ARC5] Trivial question. Meaning of "SCR"

[Leslie Smith]

Hello Bob/List-members,
Once I believed "SCR" meant "Signal Corps Radio" and then I came to
believe it meant "Set - Complete Radio".
Now I don't know what to believe.  Maybe I'm ready for reality TV?
If I don't know what "SCR" means will I be voted off the list?

What does SCR mean?

73

PS  Some people think "SCR" is a 4 layer thyristor, but they are just
plain WRONG there!
