Nav Map Plot (Contacts on) Note 4 degree difference

Found my problem while messing around taking screenshots, then plotting between. Game on pause between actions, and while plotting. Still getting a 4 degree error, but may be because target moved even in that short a time.

TF and Convoy
 

I would like to hear if anyone has had success with tracking a TF or convoy. I haven't been able to get consistent readings even though I have been trying to fix the radar beam on a particular ship. It ends up that I have two or three readings that appear to be the same target. Then my beam seems to pick up another target and a much different range.

I don't worry so much about the accuracy of individual range and bearing readings. If you take enough plot points it will still average out to be accurate enough. I still haven't had a chance to play with this mod. But the unmodded radar was wildly inaccurate guessing game! Maybe I can try this mod tomorrow arvo

You will never be able to track an entire task force or convoy... it's too much work.

What I do is maintain whatever course I am on (ie don't change your relative position to the contacts) and track the last (or first... your choice) contact spike on the A-Scope enough to get a rough range and course. I plot that on the map and then get into a intercept position and wait for them to come over the horizon. Once you have a visual you can lock one target in the TBT. change course to match theirs and go ahead standard to slow their closing rate, spend a little time getting a pretty good solution on it and then get into a really good intercept position. Submerge, and use the periscope, stadimeter and AOB tools to get the shooting solution.

Then I let go with everything I have and make a dignified withdrawl.

I hear what you are saying re TF/Convoy. However, once a warship spots your boat, surface time is limited before its begins to shell you. I believe, although I am not positive, that will prevent, as a practical matter, the use of radar to track, etc., unless a captain is willing to sacrafice his boat to fire from far away deck guns of the TF/convoy.

Or you could run at radar depth for a while.

You should be able to stay at about 5,000 yds and have visual contact without them spotting you (esp. at night). and still be able to lock the TBT onto the target. IRL the Archer-Fish tracked the Shinano at visual range and on radar for several hours before a bad zig by the Shinano put her squarely in Archer-Fish's sights.

Or sergei's suggestion will work but will limit your speed and increase the closure rate.

Trust me, with time and practice, it will come. Where I really started to get good at it was in an actual patrol. So far 4 enemy hulls are on the bottom, 12k tons, with an expenditure of 19 torpedos. Allowing for duds and misses this is the most histoprically accurate total for a patrol I have ever had.

And the most fun.

no one has fessed up that have tracked a convoy/TF with success. Daytime is probably out, because if you are on the surface too long, you are dead meat. Night time is possible theoretically, if you can manage to track a single target on radar, which I have found to be very difficut.

And, if you do track one ship in a convoy or TF, what if it is a DD? If you are hunting the bigger fish, how do you transfer the TDC from the DD to a BB, for example? If that can be done, we are in business. (I am trying to figure that one out and am thinking about it.)

In a typical convoy the merchies will comprise a more organized "block" in the "middle" than the escorts/DDs. You can even set the radar to"focus" on a specific target and take its bearing and range.



.

All ships in a convoy will have the same course and speed, otherwise they wouldn't be sailing together.

true. so, if I want to attack a target different that the one I am tracking, I put the scope on it and get its range?

Yes. You should already have speed and course for just about every ship in the group so all you need is final bearing and range.

Battle of Philipine Sea
 

I am getting closer. I tried tracking a TF. I got three good range and bearings at 29K yds. So I set the TDC for the TF course at 70 degrees. Then, when I tried to get speed, I had difficulty. I had a computer speed of 19.75 and went with it, but my plots are around 11K, plus they revealed a possible different course. The long and short of it is that I fired on AO (carrier?) at 2000 yds., and the torpedoes ran several hundred yards ahead of the target. I need more practice, but at least the carrier was in the neighborhood. I think the day glow sign above my ship that said "Using Nisgeis Brand New 3D TDC Device Plus Channing's Training Manual with Hits Guaranteed" gave away my position.

Well, I did hit something in Mission No. 3. But everytime I try to make a screenshot, I get a thumbnail.

Well done.

Still have problems
 

My persistent problem is that the target dial on the upper left of the 3D TDC appears useless in setting course. If I move the white triangle on that dial to 220 degrees, the movements on the ship's dials on the upper right do not comport to that course. And when I send the 220 degree course to the TDC via the Aob dial, it ends up at some other course which matches the triangle(or the two triangles on the ship's dials on the upper right?) is at when I recheck the 3D TDC screen to see what the hell happened. I mean, moving the triangle on the 3D TDC screen to 220 degrees is straightforward, and this should not be happening.

On the other hand, if I move the two ship's dials on the upper right of the 3D TDC to 220 degrees and send that course to the TDC per the Aob dial, it works (for awhile) and then the course begins to change. When it changes I can reset it, but what is going on?

I assume I set course with the PK off, and turn the PK on after I have entered it accurately.

What is the story? Has anyone else experienced this problem?

Getting course is not a problem. I have figured out a shortcut, which involves taking a range and bearing, writing them down on a notepad, using the pencil to plot the point on the Nav Map where the reading was taken, and using the protractor tool to plot the angle. I do not plot the range. I plot the range after I have taken 3 or 4 readings per the above. It is a time saver, and is helpful if you make a mistake, as you can observe it fairly quickly on the Nav Map.

Yes, that's right. When you use the wrong dial to set the right information, it doesn't work. If you want to set the target course, use the target course dial. DO NOT USE ANY OTHER DIAL TO READ TARGET COURSE FROM APART FROM THE TARGET COURSE DIAL.

As for the rest of your question, if you have entered the initial problem (range and bearing, speed and target course (AoB)) and have the PK running, DO NOT TURN OFF THE PK FOR ANY REASON WHAT SO EVER.

:cool: Paste your screenie to MS Paint and save it as a jpeg. Then upload it to Photobucket.

Here they are. I still cannot get a full size screenshot even using photobucket. If someone can give me specific sizing instructions for MS Paint and photobucket, I would appreciate it.

First shot is the the plot. Second shot, torpedoes 1 and 2 miss aft. (Pic too small to see torpedoes' wakes) So do torpedoes 3 and 4. Third shot: Torpedoes 5 and 6 make contact. Map contacts off. Range: around 2,000 yds. Target course: 220 degrees, heading from NE. Note: the target has passed 0 degrees and was pulling away.

Note: The plot: Red circle re No. 1 shows copies of the "x" I placed on the Nav Map to extend the plot to a long distance. Red circle no. 2 is the bearing angle plotted for each of the three plotts. Course reading per compass tool was 220 degrees.

Okay. I understand your reply. However, sir, if it is correct then Mr. Channing needs to rewrite a portion of the tutorial. He clearly states that you should drag the white triangle on the target screen on the upper left of the 3D TDC to the target's plotted course, and that the two triangles on the the Target Course screen on the upper right of the 3D TDC will move in a corresponding matter to match the plotted course. I blindly followed Channing's instruction without success on several occasions. It was only when I disregarded his instruction re the dial on the upper left of the screen, and only adjusted the dials on the Target Course screen, that I properly sent the target's plotted course to the TDC via the Aob dial. On top of that, moving the twin dials on the Target Course Screen is not simple, especially when you have to move the two dials from a course of, say, 100 degrees to a course of, say 250 degrees. Please respond re the tutorial, as no one else has weighed in with this problem.

By the way, it is time for a master gunner like sergi to make a video tutorial. Reading, seeing and doing are a fast way to learn.

I am off to sink the third ship in Tutorial No. 3.:D
