Is your HYDROPHONE busted too?
 

I noticed this after I installed v1.3 and TMaru. When I go to the hydrophone station and I man it myself I cannot hear ships (merchants that have motors running) that are right in front of me. I know they are there because I can see them clearly through the scope. However when I point the hydrophone in their direction, no sound and no green light.

What is even more strange is that when I ask the sonar operator to track the nearest target he does! He is able to track the ship that has no sound. No green light either but he happily tracks it.

This obviously does not help when scanning for ships below peri depth.

Please help. Thanks!

If you think its bugged, disable the mod, and delete
\Data\Library\USSubParts\Sensors_sub_US.sim from the mod and enjoy your hydrophone contacts while on the surface.

I'll be adjusting the file later to a less aggressive fix, its on my list of things to do.

I'm too busy being on the bridge watching the waves splash all around me to not even think about the hydrophone :)

I get the same behaviour too: No hydrophones above 40' but the SO will often track targets anyway despite surfaced. TM1.4

I usually get that in horrible weather. I'm locked onto a target 2000m away your I can't hear it on hydros. I need to manually ping the bearing and only then do I get a lock.

Correct me if I'm wrong but the normal sound frequency stuff is the two "balls" below the hull and is responsible for passive listening. The complete sonar/hydrophone set includes the "T-bar" fore deck device which allows ultra-sonic (higher than human hearing frequency range) operations such as pinging.

If anything the ping shouldn't work until that "T-bar" is submerged but the passive hydrophone part should work pretty much 24/7.

I take issue with calling the high frequency sonar system "supersonic" as this means faster than sound. I believe ultrasonic is more appropriate.

i dont think itS TM, i dont run TM, and i have the same problem.

worse, when listening to approaching convoys, at the center of the sound, it sounds very static, and framerate drop to about 2 fps, once i get off the center of the sound, it goes away, and FR goes back up.

i am in tokio bay right now, about 8 miles south of the city, im there to phote recon the harbor. i was discovered and was attacked by six warships, one coming from each city in the bay.

i took some bulkhead damage, but im still able to be at 247 feet with no problem., but both scopes have been blown off, cant use them to photo, will have to use tbt, when i get to tokio.

but during the DC bombardment,and thier searching, which has lasted for more than 12 hours, sometimes asking SO for closest warship, give me a beaqring of a warship at long range, when one of them is going over my head at the moment.

also when asking SO for closest warship, will give me a bearing, i go to that bearing, and theres nothing there.

before my scopes were destroyed, i observed a gun boat coming close, and no propeller sounds with it.

WIERD

Hydrophones were much less effective if not useless while surfaced.

Sheese.

Duci,

Sorry man. I wasn't blaming TM. I should have mentioned that this happens in 1.3 stock as well.

In fact, right now I am outside of Tokyo bay and I am having the same result that Greyrider is reporting. There is a gunboat at 85 deg bearing and a merchant at 10 deg bearing. Both are within a 4000 yd radius (easily seen through peri) and both are non existant on the hydrophone. I am at 60 ft peri depth. They are plowing through the waves so I should hear them.:ping:

I think the devs broke the hydrophone when they removed the ability for the sonar man to detect sampans. :roll: :roll:

Anyone know of a fix?

Hydrophones!!! What are the heck are they? :roll: :lol:

Its a phone you use to call water of course ! :lol:

something i've noticed of late. the light would be green, i ping it and get a "no sound contact". this is quite frequent and i think it's post 1.3:-?

I get a green light, no engine noise, and no text (merchant/warship/unknown) pretty often. It means I've detected something with a broken engine, no engine (like liferaft/downed-pilot).

As far as the SO Report Contact function working when you cannot manually listen to the hydrophones, makybe the SO is just spewing back the last contact report saved in memory and it's not at all accurate?

You got it in reverse:

No worries. Alot run TM, and havent played stock as much, so it usually goes"such n such is broken after running TM". If it occurs in stock, FEW people say so. Since i mucked with the sensor, i have to assume the worst, despite the fact that i tested it with, and without my adjustments to make sure submerged performance was what is should be. After being "reminded" about it, a few times, i get testy.

For what its worth, i noticed the same behvaior with a US liberty ship. Doublechecking .. acutally TRIPLEchecking my sensor adjustment is on my list of things to do, but ive been frying bigger fish, so havent gotten to it yet.
