Ok.Look at the installation in the SBD Dauntless.The radio operator 
/gunner would have a heck of a time with the radios in flight.All 
situated below his waste level.Same with the Kingfishers and Ducks.You 
really only got to play with the DU and the key.The TBM/TBF had a radio 
position but the missions probably did not require much attention to 
the radios as the radioman was also the torpedoman.Now, in the 
Catalina,Mariner, and Mars and the (can't think of the name) PB2Y 
?(Ah,Privateer?) (B-24 upgrade for Navy) there was lots of space to 
fiddle with knobs but since everything was mounted where ever it 
fit(even in the galley!), ergonomics probably wasn't the first priority.
  (Now, in the systems I've built, ego, I mean, ergo has always had 
first dibs....)

  PS I'd like to read 11 pages on a knob!I have a hard time with the 2nd 
paragraph of IEEE papers...

Not really true. The ball really started rolling with ergonomics in 
the 1930s, and RCA was on top of it. The BC-348 is pretty nice 
ergonomically because RCA expended resources to make it so. 
 
For example, the "RCA knob" found on Navy equipment (and a few 
aircraft sets, like ARE..ARH) is highly sought after because it really 
is a good knob. I have seen the original report RCA wrote on the 
studies of that knob - I think it is 11 pages long. All to make sure 
you are comfortable turning a shaft. 
 
Certainly ergonomics was not the thing it is today, but ARC managed to 
show almost complete incompetence with the ARA/ATA (RU/GF is not 
nearly as bad, I think, but that might be due to simplicity). RCA, GE, 
Westinghouse, Western Electric, and Bendix had a few hiccups (ATD 
leaps to mind, although the problems are confined to the transmitter 
itself), but in general showed excellent to good understanding of the 
science - which really is a whole lot of common sense, when you boil 
it down.
