Yes, the SJ radar did use the A-Scope. The A-Scope gives range readouts, the SJ, bearings. Don't believe me?:

Actually, that's the SJ - Surface search radar. The SJ first appeared with an A-scope type display and later - through the SJ-a/SJ-1 version, gained the PPI type screen.
The SD - aircraft search radar - also had an A-scope, and was non-directional. We don't model that one as mannable station.

Yes, I know the early SJ used an A scope. The question is, did it require both the A scope and the PPI at the same time? If so why? PPI clearly provides range and bearing. So if you've got that what's the A scope for?
