Well I indeed wasn't updating my AoB while I was doing this so I will try again, and while I'm at it I am downloading TMO upon the suggestion I received earlier just to see if maybe I have a bad install of RFB.

Thanks for all the help guys, but I'm going to sign out for the night.

I'll fiddle a bit more with it before hitting the bunk and try and report back in the early.

going to bed are you?
 

:yawn: A rookie for sure!

Subsim skippers do their best hunting a night. We hide during the day plotting (no pun intended) to scare the hell out 'em when it is dark and wind howlS :arrgh!:

One final minor point. Be prepared to have your ass handed to you by Ducimus' famous dds in TMO. You might want to brush up on evasion tactics, because the dds hunt meat.

Sorry you're in difficulties. I know the frustration factor can be high in this game.

I don't know about the O'Kane method, or the other SubSim methods, but I have a few suggestions.

First, if you have a mission where you can target a single ship, that would help. Trying to con your sub in the midst of an IJN task force is not a good way to learn. Unfortunately, the RFB training missions are of little help.

Second, I would encourage you to drop the O'Kane method, for the time being. I'm not saying the method doesn't work, but it is not essential to the use of the TDC. I think you would be better off to learn the TDC first, then worry about the O'Kane method.

Assuming you have Aob, speed and range.

1. Turn on position keeper. The 'GSP' light should stay on.
2. On right dial, dial in Aob, hit send to TDC button.
3. On right dial, dial in speed, hit send to TDC button.
4. On right dial, use stadimeter to get range.
5. With PS on target, hit send to TDC button to send both range and bearing to TDC.
6. Repeat steps 2 thru 5 in succesive observations.
7. When firing solution is good, fire torpedos.

It is not necessary, to shoot with scope up, right after step 5, but any inaccaracy in your data will cause the firing solution to deteriorate over time. Also, a small gyro-angle is not required, but was favored by captains, as it was more tolerant of errors. The Mk 10 torpedo gyros can be set up to 90 deg. no more. When you input data into the TDC, you should be able to see some movement in the dials on the left slideout. If you are putting in accurate date, but the readings on the left (updated by the position keeper), make no sense, something is wrong.

If you like, I can tell you how to manually obtain a firing solution (no TDC), but I assume you will want to learn the mysteries of the TDC anyway, since it is such a central element of the game.

I'd be interested in seeing a no TDC method. Anything to add to the list of available techniques is another option.

That's one thing about this game. There's so many different ways to play.

torpex and razark
 

Torpex, I think it is an ill thoght move to recommend a skipper switch horses in the middle of the race. O'Kane teaches much, as it was the ideal position to fire in WW2. He will learn the concept of the lead angle calculated by the TDC, which cannot be avoided unless all the Attack Dials are set a zero. Let's wait until the poor SOB solves O'Kane, which is not that difficult, sinks some ships, and then he can move on to conquer his next problem.

O'Kane skips steps 2 and 4 in your scenario. How to you want him to calculate Aob? With the protractor tool, or are you using the Easy Aob mod? I am being rhetorical and do not need an answer. The point is that O'Kane works without those steps.

Razark, the constant bearing technique by RocknShoals is an attack with the TDC off. Like O'Kane, the TDC calculates the lead angle.

The most precise way to calculate the lead angle with the TDC off is gutted's Solution Solver Program. You can attack at any angle and the program will give you the lead angle. It is O'Kane gone berserk!

I've been reading this thread, scratching my head trying to figure out where our friend is going wrong. I'm useing the same combo (RFB+RSRD), and regularly use the DO method with success. The most important piece of info with this method IMO is target speed. Getting this wrong will kill your setup. Reading along though, it seems you've tracked the convoy pretty accurately, and are confident with your figures.

I know you mention that you've watched RR's video a bunch of times, but then you say you entered the AOB as the first piece of info into the TDC. IIRC, RR enters the target speed first, AOB second, and range last. Speeking of range, are you "dragging" the small plastic triangle on the range dial down to it's maximum before entering the range by clicking twice? You seem like you know what you're doing, so please forgive my basic questions. Like I said, I'm useing the same mod combo, and DO works like a charm. I don't think this is either a RFB or even more so, a RSRD issue. RSRD only changes shipping routes to historical values. I would try to contact RR, or hopefully he sees this thread and chimes in. I believe this is a simple case of overlooking something simple.

Good points! Once the OP is done mastering this technique you can go to this thread and start working with a very realistic rendition of the USN TDC/Position Keeper and Radar by Nisgeis and Hitman! This is just awesome in scope and complexity 'no pun intended'!

Enjoy! http://174.123.69.202/~subsimc/radio...hlight=nisgeis

Happy Hunting!

Wilcke, sending him off to Nisgeis 3D TDC at this point would drive him to suicide. He hasn't solved O'Kane. Something tells me a 16 or 17 step attack scenario using radar is over his head at this point.

By the way, I saw the videos you referred me to in the ATO forum. Good recommendation.

I did say he should master the basics first prior to moving on.

RSRDC is not the problem in any event. It adds a campaign layer to the game. I doubt the issue is RFB, which may not show the torpedo track in any event. The problem is your method.

If a turkey is flying by and you aim a torpodo at it and fire with no lead angle, the turkey will be gone by the time the torpedo intersects the gobbler's course. However, the TDC operates even if the PK is not activated. It will calculate a lead angle based upon the speed and Aob of the turkey that you have input and sent to the TDC. (Distance is not a factor as range is set to maximum.) The TDC will compute a lead angle regardless of which mod you have activated. If the turkey is doing around 8 kts., the TDC will calculate a lead angle of about 8 - 9 degrees. However, you must fire when the turkey crosses the wire to hit it. Why? Because the TDC is not activated. Thus, it is not tracking the turkey. Since it is not tracking the turkey, failure to fire when the bird crosses the wire means you will likely miss the shot. If the TDC were activated, and you input the turkey's range correctly, the TDC would track the gobbler and you could fire at it when it was in a myriad of bearings assuming it does not veer oft its flight path (i.e. course.)

Why do you set up so that torpedo intercepts the target at a 90 degree Aob? Because that is when the target's profile (aspect ratio) to your boat is the longest. In layman's terms it means that you have a bigger target. A flock of turkeys closing at a zero degree aspect ratio [zero degrees Aob, meaning they are heading right at your boat] has the smallest aspect ratio. A flock of turkeys crossing your bow with an Aob of 90 degrees presents the largest aspect ratio possible, and means you will likely have them for lunch.

For some reason I suddenly feel the need for a turkey and swiss cheese sandwich on a French roll. Chief, tell the cook I like it toasted on a French roll with a bottle of Sopporo from those cases of beer that we salvage from the Biyu Maru we sunk a couple of weeks ago.
