What do these do?

[Palindromeria]

in general setting the sonar sensitivity in the sim ini to 0.7 or 0.8 helps.

you can also mess about with CrewRating (0.3 - 1.0) at each wep/sensor in the udf.
it doesnt affect every station equally. in some cases you might note no change.

this is from the stock nssuboat9Cgun found in sh2 unit folder but not used in game

[WEAPON1]
Type = TURRET
Node = Main1
System = Gun105mm
ElevRange = -10,50
TravRange1 = 0,-165,165
CountAmmo = TRUE
MagazineCount1 = 150
CrewRating = 1.0

these setting if they do work likely function directly on the destroyers sensors rather than the subs--(they are on one or two stock destroyers after all )

so it's allways worth banging them in all the DD's in the hope that it might enhance gameplay--

i got the sense that they did work--especailly the noise--hard to test of course as there's no debug system to show the figures--

try
[SOUND]
EchoFront = 100.0
EchoSide = 100.0
EchoRear = 0.0
Noise = 100.0

for example to help generate the rear ward blind spot--

can't remember exactly what set i used of hand--

but i worked on the idea that if it did work then wonderfull stuff --if it didn't then it's just text in a file --end of story--
