D/L'd and read the readme, but I still can't figure out what it is about the hydrophone that this is supposed to fix - my two best guesses are:
(1) fixes the external animation where what seems to be the hydrophone sound heads rotate for a while and then sort of click backwards and start rotating again, instead of continuing to rotate smoothly in the same direction for a full circle; or
(2) introduces dead zone internally while listening to the hydrophone station, if US 'phones couldn't actually hear a full 360 degrees (I think I remember reading that the German ones, at least the early ones, had some dead zones directly fore and aft, but I haven't read anything about the US 'phones one way or the other).
Can you tell us what this mod actually does?
Thanks
