Changes fumo391 radar to radar warning to use on top of the snorkel in the xxi.
I tested on my career and seems to work fine submerged with the snorkel up.
NYGM version 2017a.
Don't SELECT fumo391 in the list as a radar warning receiver, it is going to be added automatically if you do you get destroyed RWR antenna etc.
