I had some time to kill today so I played around with the mission editor. I started from the bottom of the list of IJN merchants starting with the small old split freighter and worked my way up.

Here is how the scenario was set up. I place the merchant heading north toward Kiska. Speed was set at 10, then 8, then 6, 5, then 4. My sub was placed about 4000 yards off the starboard bow of the incoming merchant at PD and then various depths to test the phones.

So for the first test the merchant's speed was set to 10 knots. On the phones she came in loud and clear no matter what depth ( except surface ). Same result for speeds of 8 and 6 knots but when I dropped below 6 knots I could not detect the target even though my crew tracked the merchant just fine. Any speed below 6 knots had the same result.

I repeated this test for the first 5 merchants in the IJN list and had identical results. Once a merchant dropped below 6 knots it was not detectable on the phones even though my crew could track the target and I imagine if my realism was cranked down you could see the sonar bearing line as well.

These results were confirmed regardless of depth and speed of own ship but of course you have to be submerged and atleast PD to use phones.

I have no doubt that even if the merchant was dead in the water my crew would find her even though you would not be able to track her on the phones yourself. Sounds like I need to test that one.

I have not tested the same hull from multiple nations but I cant image they would be any different. Is this new information? Probably not but it does seem to relate to many questions above problems with the hydrophones.

I seem to vaguely remember something in the 1.4 or 1.5 patch read me files about this change but I havent gone back and read it again.

I wonder if anyone else has had similiar results?

One more note, my install is very clean and recent, but I am not ruling out that my install could be corrupted I just have no reason to suspect so.
