Noob problems part 2. Please help me!

[mundio_73a]

Hello!
My previous post was probably incomprehensible.
I will write again, a shorter message.
I have the following problems:
A. I am converting from the "Op. Monsum v. 705" Ubot Type XXIII mod to an Allied ship - what should I do to add a radar to the equipment?
In the "Op. Monsum v.705" mode - this ship does not have a radar, the radar tab is inactive in the game menu.
B. In the Hydrophone - the noise of my ship's propeller can be heard at a bearing of 0 degrees, and not as in other ships - at a bearing of 180 degrees.
What can be done to keep the ship's own noise at 180 degrees?
What value should I enter in the X axis rotation in the dat file to reverse it by 180 degrees for selected devices?
C. I have noticed that many multi-barreled guns fire all barrels at once, while others fire sequentially. What should I change in the gun configuration files to make it fire from all barrels simultaneously?

I am asking for any help and advice,
