My Radar Officer picks up the contact at roughly 19nm heading 116 relative to my ship.

I turn off the radar, then I select heading 116 in the Hydrophone and click "Follow nearest contact" with a reply "SO No sound contact"

But if I select heading 116 with the Hydrophone and click "Report Contacts" I will then get a reply "SO nearest sound contact: Merchant moving slow! Closing! Bearing 116! Long Range!" I just checked that I do not need to move the Hydrophone to 116 to use the "Report Contacts" But I still can not hear anything when I do this manually. These officers must have super human abilities.

I thought, from my understanding that selecting "Follow nearest contact" tells the officer to keep me updated at predetermined intervals of where the merchant is? Of course, "Follow nearest contact" does work when the merchant is closer to my position.

Maybe what I am experiencing is normal, but the noobness within me somehow tells me it is wrong? (Translation: I am experiencing what should happen rather than what I think should happen)

My only previous experience of SH is in SH3 where I thought it was too difficult and never sunk anything and only played it for a short time before deleting and trashing the CD. But, as I am a simulator freak I decided to get SH4 and try and learn it properly. I already have learnt much more in using SH4 for a week than what I learnt in SH3 in a couple of months. I can actually blow a ship out of the water but that is a thanx to the awesome video tutorials, something I never had in SH3 when it first came out.

P.S I think the manual sucks big time. It states very clearly how to use the software, but explains nothing of how to play. So glad I found this site.

It doesn't sound quite right that's for sure. You should be able to hear the sound from the hydrophone, espeicially if the SO is hearing it. In fact, you should be able to hear the hydrophone contacts before the SO hears them. At least that's my experiance. As for as the mods you have, I agree, they shouldn't have any effect on this.
The only other thing I can suggest is maybe trying a reload if nothing else works, (I'm sure I read that your running at least 1.4).
Yeah, the manual really is an unfinished work but me and a lot of other sim skippers learned from reading and sharing on this forum, it's the best I've ever had the privlige of using. I couldn't hit the broad side of a barn with Auto_targeting when I started playing and now I'm having loads of fun playing this game, in fact it takes up a bit too much of my time if you ask my wife.
Good luck and Good Hunting.

Yeah, I am using 1.5

You said: "The only other thing I can suggest is maybe trying a reload if nothing else works"

What does this mean exactly? Reinstall? or just reload the mission?

If its the latter then it does not do anything as it is a simple mission that I created with a single merchant so that I can learn the principles of solution solving using the different techniques available before I go into battle proper.

How big is this vessel that you're trying to track? I've noticed (on a few occasions) that small vessels travelling slowly in rough seas, and heading toward you with screws behind them (as opposed to broadside or moving away), are sometimes difficult (or even impossible) to pick up on sonar until they're much closer.

The merchant is just over 7000 tonnes, and moving towards me. (Large modern composite freighter)

:stare:I'll be danged if it didn't just happen to me. I got a hit on a IJN merchant and I heard it through the Hydrophones. Then as I'm coming back into Manila, I get a hit on an Allied merchant and the SO calls it out so I go down for a listen and it's not there.:06: It's on the map, I can ask for the latest bearing and the SO pops it off but if I try and hear it personally,,,,nothing. I think I'm going to try and find that fix myself!!
If I find the magic fix, I'll post it here.
D40:salute:

Keep me posted on that magic fix will ya buddy?

At least you'r SO acknowledges the contact. The only person that shouts 'Ship Ahoy!' is my RA. And like I said earlier, eventually my SO does report, but the contact is within 10nm by that time.

But, saying that, even with my problems I guess I am not doing too badly. Started my first career in 1944 and was ordered to patrol off the coast of Tokyo. First contact were a couple of small fishing boats, so I thought, what the hell, they would probably give my position away if I let them go so I surfaced and took both of them out with my machine gun.

Second contact was a Passenger Liner and I decided to take that out by using the stadimeter approach to gather speed, bearing and AoB. 3 of my 4 fish hit which I was a little happy about because the sea was a little choppy making the use of the stad' a little tricky.

And my third contact was a little ship weighing in at just over 1000 tonnes, cant remember the name. And I decided to take this one out with the Dick OKane method. Both of my fish hit.

4 boats, 3 attack methods, and one lost fish out of 6. All in all a good start to my career and I still have some ways to go before I finish my first patrol off the coast of Japan.

I guess learning how to get a solution and attack a ship in a very simple user created mission was worthwhile after all. (Manual Targeting = ON)

What get's me is that it's just that one ship. After a time I pick up another as I'm going into refit, this one I can hear just fine. Both my SO and Me personally, it's on the map as well.
I hope I can find the problem or the fix. I have a lot of mods installed and I would hate to find that any of them is to blame.
More shall be revealed...

They're a few bugged ships in stock when under 7kts don't show up on sonar...just can't remember which ones.

Yeah, now that you mention it:hmmm:, I vaguely remember something like that in the stock version. The funny thing is that, sometimes you can hear them, sometimes you cannot. Could be the same ship on different occasions in fact. I have a vague memory of a subchaser doing 5 knots that I could not hear on sonar. Didn't have a visual on him at the time either. It wasn't until he came into PS view that I could identify the boat and it's speed. If that's the case, I think it's all up to the throw of the dice.
