Is your HYDROPHONE busted too?

Frederf · 08-02-07, 06:42 AM

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.

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.

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

Anyone know of a fix?

Hydrophones!!! What are the heck are they?

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

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.

I've seen the same thing in stock 1.3. Occasionally the sonar operator will track a ship and I can see it but not hear it when pointing the hydrophones. I've also had the opposite happen, where I can hear it in the hydrophones but the sonar guy won't track it.

SteamWake · 08-02-07, 05:03 PM

and this is all while at periscope depth ?

Ok then it all makes sense! I shouldn't be able to hear the sonic gear until I get the T-bar below the water level. That means no hydrophones on the surface and it's realistic! No bug, no foul. I'm gunna have to read all that manual now you know

What would be the sensor functionality with the sonic gear in air and the supersonic gear under water? Nil? Some?

Well not only "while surfaced" the sonar would become swamped with white noise when near the surface (periscope depth). Waves crashing, bubbles, shrimp screwing, fish farting etc. making it more difficult to pick the sound of a ship out from all the backbround noise.

Why for the love of god would you use the hydrophones while at periscope depth if you can see the ship with your own eyes thru the periscope

Because you can hear further than you can see.
