i am playing DW, at the moment, and my boat has the German counterpart to the APR-1 and it cannot be turned off either.

I am guessing (like most things about the game) that it is because it is passive. Nothing "active" about it. What I did the other day when testing, was to remove the crew from the conning tower, and there is no longer anyone to man the sonar and radar station then. You still see the "lines" on the NavMap, but not all of the voice and time interruptions. The framerate improved also, from not having to track all the "Radar signals detected. Bearing: 356" etc... lol

ok, then why would someone place comments in the Upgrade file that warn Kaleuns about using the APR because it can be detected.
if the system is passive there should be nothing to detect.
are the comments incorrect? if that is case, then this is easy to fix.

Now, the US devices were passive. Some of the German devices were active... they could detect radar of a given wavelength out to say 8nm, but by then, the Ally's radar was a smaller length, and could see 15nm... that kind of thang...

So we must turn off both SD and SJ to avoid active emissions?Are both radars detectable?

In FotRSU, yes you do. In most other mods and stock, you cannot turn-off the SD unless you submerge... However, going by your question, I would be willing to bet that this has not adversely affected your patrols too often... lol - Primary goal is to sink ships. In conducting said goal, number one chore is to not be seen. To minimize that risk, you use radar. However, the enemy can home in on your radar signal, just like they can the radio signals, so if you want to do things the "realistic" manner, you use 1x TC like Front Runner does, and then sparingly use your radars, such that you are aware of your surroundings, but not having a contact "beacon" sounding... Myself, I only do the intermittent stuff occasionally, else you would be out there on the boat for four years...

Thanks propbeanie.
My strategy is to always use both radars on but I wasn't sure which of the two are detectable when operating. However I don't mind very much about my emissions, although there are annoying situations where enemy planes constantly fly towards my sub due to that reason.In that case maybe I switch off both.
