Hey guys,

I've been diving deeper and deeper into sh3 as I find my way around the old girl again (the only game I have as many hours on as this is Kerbal Space Program, which I discovered from a post on THIS forum!!!!!!!!!) and I'm running up against something I had issues with back then too...

Hydropones. I get that they are a really powerful tool for the uboat. I can do 4 bearing TMA and so on... but there seeems to be a hidden 'art' that I've never clocked. Using the Hydrophones to ID and guage target speed ect. I'll be honest I've always been reliant on the notepad to id merchent from warship, and I get that I should be listening to the engine noises 'under' the prop noisses. I also get that the prop noise will give me rpm.... but try as I might I'm useless.

An example... just cmae across a patrolling C or D class destroyer in my current game. I know it's that from the vis id I made. I dived to periscope depth so as not to attract attention then went to the hydrophone and had a listen.... my hydro guy seems useles (he didn't pick it out) but I could easily (espc. with the lautstrake knob). I can hear the prop and the enginge pretty clearly, and seperate them out.... but if I hadn't vis id'd the target I'd have no clue if it was a battleship or a costal tanker!


Is there any mod that improves the engine sounds of vessels? THomsen's sound pack p'raps? RPM tables for SH3 or GWX? Techniques? Tricks?


Help!

Mod list that may impact things:
GWX
MEP 5
Sh4 effects in sh3
MaGui

Download this document Collection:

www.subsim.com/radioroom/downloads.php?do=file&id=1487

It contains Raduz's Hydrophone Hunting Tutorial. It explains the basics. Friede Rösing made up to date speed RPM charts. You can find the charts by googling or from my CAWS 1.61 mod over in SH3 Downloads section (gameplay mods).

An additional hint: I've found that sometimes I can personally find a hydrophone contact and THEN tell the operator to track the nearest one - they can often then lock onto the one you heard.

I think that there is also an range / type / RPM document out there somewhere (perhaps in the previous link).

I only use hydrophone for listening the song of the whales. It is so beautiful and romantic ...

thanks guys, espc. Sublynx - that doco collection is insane!

I have a feeling the rpm count is liable to be unreliable the moment I install thomsen's soundpack (late night decision last night after I posted), but the rest of it is exactly what I'm looking for!

A quick browse through shows a ton of tricks I had never tried and some great patrol blanks!


cheers guys
