Well, that is the "normal" behavior of the SH4 radar. It gets "wet", it assumes it's going under the surface, so it shuts-off. Wave finishes going over you, it gets "dry", time to turn back on. Now, if you're like me, you want a radar off, or you want a radar on. Turn it on, let it sweep a few rotations, find something, turn it off. No need to have a beacon saying "here I are!!!" But the game does not do that. Oh sure, you can turn the radar off (FotRSU <Ctrl><T>), but first wave over the conn, and presto-change-oh, and it turns back on, because it got "wet", then got "dry", and "time to turn on again". Short of a hammer, I don't know how to keep it turned off after it gets "wet", nor do I know of a way to keep it on for those short spurts of "wet"... someone else might.
