(req) black out PPI screen on early SJ radar
 

Anyone think they could black out the PPI screen on the early SJ radars? My understanding is the SJ-1 radar that appeared in late 43 and early 44 is when the PPI screen came around, not the biggest deal but an imermsion tissue for sure.Perhaps could make a mod to enable that disables the screen prior to late 43 .Again, would do it myself but no clue how to do so.
