My guess is that the radar warnings did not give a direction as in U-boat KTBs they always give the bearing where the threat was if they knew it. Radar warning texts in the KTBs only mention the duration and the wavelength of the signal, visual sightings mention the bearing, height and speed.

Thanks for the ability to separate between different hydrophone signals! This will make underwater attack planning so easy that I might have to restrict myself from using certain procedures that are too gamey!

He, he... I can't count the times I've spent a long time doing hydroplotting and suddenly a trawler shows up and f**ks it all up.
But you're right. It probably gets too easy sometimes. Haven't tried it out yet. Maybe I'll have to counter-patch it somehow.

Thanks for the replies!

Concerning the bearing information:

I have tried very hard to obtain reliable information about that. However, this is quite difficult. If you look at the Biskaya Cross it's clear that you should be able to get a direction-dependent signal. However, was it ever used that way? I doubt it because it would be quite cumbersome with someone rotating the Biskaya Cross by hand and the operator down in the boat. In addition, I have never found any evidence of such procedures in any documents (like sublynx also points out).

Anyway, the current situation in SH3 is very unrealistic. You can use the RWR perfectly to shadow convoys, ships,... It's much better than the hydrophone!

I think the main problem is that SH3 does not model the different radar wave-lengths and which RWR could detect which wave-lengths. Even Metox in SH3 can detect 3cm radar Thus, you can easily shadow all ships with Metox even if they have 10cm or 3cm radars.

To circumvent the problem I have changed my RWR to detect only signals from sources 50m above sea level --> no ship contacts. And for plane contacts the bearing information is not very useful.

But I would love to see any clear evidence that u-boats used (or did not use) RWR to detect/find/shadow ships. And information about which antenna provided bearing information and which didn't.

I know very little about these things and I'll trust you as an enthusiast. If you haven't found anything so far, then maybe its because they never used it that way.
I haven't played much with radar either, so I don't really know how it affects the game play.
I'll put it on the wishlist, and we'll see if I manage to find anything while examining the code.

Here's a line from the KTB of U-466 from June-August 1943:

Dived for detection on 134 cm wave, 2 second impulses, recurring. Skilled operator. [Used radar] sparingly.

http://www.uboatarchive.net/KTB466-3.htm

The allied started switching their radars off now and then while approaching the U-boat to lessen the possibility of getting detected by RWR. Maybe this could be randomized somehow in order to have the crewmen sometimes miss the approaching airplane/destroyer altogether?

Hi,

my guess is that a RWR was never used to shadow/detect ships. Indications for this are: a) I have never seen any source mentioning such a use, b) bearing information would be very important for this and it seems that bearing information was never much of a concern in the development of RWR, and c) ship's radar was always ahead of airborne radar in terms of wave-lengths.

If my guess is true, my workaround with the RWR height simulates real-life performance quite well ---> there are more important issues to tackle

Animated retractable antenna, but not functional. Alas, transmit messages from periscope depth impossible. It is hardcoded in the game. But you can raise and lower, stop ascent or descent anywhere at will. The movement of the antenna a little step. This is the best that can be obtained from the SMS mechanism. Just for historic justice and exterior.

Yes, it's a good idea !

[a.g.]

I wonder if it would be possible to implement a feature to auto-dive to listen on hydrophone at regular periods when cruising around looking for things to attack. You'd enable it by pressing some key combination in navigation map, and then it'd basically repeat this until time compression drops below 64 for any reason:

wait X
periscope depth
wait Y
surface

Thanks for your suggestion. I guess it is possible. However, it doesn't change gameplay enough for me to see a point in having it. Pressing 'P' and 'S' is simple enough if you like doing your hunting that way.

In that run that would be useful to have such a routine that would give you an "underwater-scan" regularly and if it finds something drops TC down to 1 so you can begin an attack run.

"wait x" could stand for a 3-hour-interval to have this routine executed.

Ok. I don't know. It still doesn't do much for gameplay. It's convenient - I can agree to that
but...
No. I will not implement it as far as I can see. Sorry.
