Actually the USS Plunger was field tested the SD radar system during its war patrols late in 1941. The SJ system (much more reliable) came about in 1942. The PPI wasn't until 1943. This (also referred to as improved SJ) is the screen with the blips and sweaping line shown. Earlier radar were not as nice.

Now I am wondering why I can't get the SD radar to work at all. I have it installed on my subs. I just can't get it to work.
