I have now made a lot of effort to make the FuMO30 radar start and end in the conning tower slot on the port side. At present, the radar aerial starts a patrol with the aerial at right angles (90 degrees) to the direction of travel. Thus it extends into the conning tower itself. It faces the same way as the older fixed FuMO29 aerial on the conning tower front. (I'm using H.sie's hard-code radar fix, which prevents the radar from being active when you load a patrol. Until then, I suppose no one ever knew the the angle of the radar at the beginning of a patrol, since it began turning immediately.)

When the radar is lowered, its final direction is always that of the direction in which it faced when the command was given to lower the aerial. Therefore, a fussy user could sail out, switch on the radar, wait until it has an angle of 0 degrees to the bow, and lower it again. But it would be better if this could be done automatically.

The obvious route seemed to be to set the rotation y axis for the FuMO30 aerial to 0 (was 1.570796 radians = 90 degrees) in sensors.dat. Also, to set the rotation of the same aerial in turm 9C/2 (a test turm) to 0 (was 1.570796 radians).

This makes no difference to the placement of the radar aerial as soon as the patrol begins.

Anvart has in the past produced two FuMO30 mods, one for GWX and one for NYGM.
When these mods are installed unaltered, with JSGME, into GWX and into NYGM, the radar aerials still begin and end at an angle of 90 degrees. This is surprising, since (in NYGM) the start, the stop, and the rotation of the D/F aerial all work perfectly.

Thus, I have yet to see any demonstration that a rotating radar aerial can be made to start and to stop at 0 degrees (as required), rather than at 90 degrees.

Does anyone else know any better? If so, what is the method?
