How many ships sink without turning turtle?

I can think of only one. The Titanic.

I believe the ship’s engineers invented counter-flooding on the spot to kept the ship level enough to launch the lifeboats from their davits.

As a result over 700 passengers survived. The engineers didn’t.

If you don’t understand that, you aren’t an engineer. Or a radioman...

You are correct! I am neither a ship's engineer, though I have logged many thousands of miles at sea, nor am I an early-twentieth century radioman. But I am a variant of what is still called a radioman.

It just seemed to me, as the radio rooms of so many ships of the "early" radio period were generally high and near the wheelhouses and aerials, that a flooded radio room would contain a particularly courageous and selfless radioman.

Plenty of ships sink without turtling, especially if they hole deeply and take water fast. My opinion is, though I am not a naval architect, that it is the heavy superstructures of so many famous WWII era warships and the great amount of footage we see of their sinkings that convinces us all ships 'fall' as they sink. To be sure, there are also the top-heavy cruise-ships, invariably captained by Italians, that make such a fuss. But per tonne? I am not so sure.
