I don't know, I've never tried it. Certainly there is no version specifically for RFB yet and if the version out now did work with RFB, you'd lose any interior changes to the sub.

Exactly and as far as I can tell, Japanese never had RWR

problem with mod
 

I activated this mod last. The button on the sonar dial is missing. When I delete the mod, it reappears.

I cannot drag the triangle up or down.

I get a reading in yds., nm's, but nothing on the spaces below.

I have a few mods activated but not many. I play tmo2.0/rsrdc.

1) Not sure what button you are refering to.

2) You don't actually drag the triangle. When you place your cursor on the A-Scope screen and hold the left mouse button down, the radar screen moves in the direction you move your mouse, the triangle stays stationary. Can you move the screen using the dial on the left?

3) The White numbers are the radar range according to where you set the triangle. The green numbers won't activate until you have a solution entered into the TDC. That's the next lesson.

the sonar man yells out bearing when you have sonar check for contacts. When the sonar is looked on the bearing, you click the button and the sonarman yells merchant at x degrees. I have no button as it has disappeared when I use the Radar Range mod.

For some reason two of the sonar controls are part of the radar stack, so when the radar got moved to the right the controls did too. I didn't spot it, because I wasn't expecting it. The switches are still there, just out of place. Using the toolbar commands still works. Will be updated soon (TM).

thanks for the tip Niesgeis
 

I just figured that out on a Gar. I stopped using the Gato until I figure this mod out.

where is the
 

I cannot find the radar range bearing indicator. What screen is it located on?

It's mounted more or less directly above the range unit - look up in the 'A' Scope view (the green screen) and it's on the pressure hull.

I would not have thought to look up there. I am now using a Gar. It is 6/41 and your mod has no triangle. Where did it go? Do you have any idea why it disappeared? Also, I will probably have to wait for Channing to get further in his tutorial to understand all of the mods aspects.

The triangle only shows up if you are in expanded sweep mode (precision mode). If you can see the range unit (e.g. it's activated) then switch through the ranges until you get the triangles back.

Shouldn't the position keeper have to work automatically instead of you manually turning it on?

The American TDC added the feature of being able to automatically track the ship.

We should be able to track the ship automatically by having the periscope locked on to it.

What about having the radar range actually work with the TDC? I also want the XO to track the target as well from the periscope.

What about the PK TDC window in the periscope station? What are you going to do about that?

The TDC should just start automatically working if you're locked on the ship in real time. All the info was provided in real time to the TDC.
Did the actual TDC work like that?


Is it possible to have the Position Keeper to automatically work and switch on when the ship is locked in the periscope? This would be more liked how realistically the TDC worked in real life.

The PK worked when a ship was tracked in the periscope. The AOB was put in to the TDC by clicking on the TDC window.

There should be a TDC station from the Toolbar in Silent Hunter IV. It would be nice to have a separate TDC station in the sub in the coning tower. You could walk to the TDC station and manually calculate it.

There are a lot of things the TDC should do, but Nisgeis is limited by what the game is designed to do.

The real PK was turn on and offable for easy control.

There was no automatic tracking. What it could do was forecast the position of a ship based on the data entered into it.

If you want to do that, you can turn on automatic targetting. It's not realistic in any way, but it will work and will populate the TDC with the correct data.

What do you mean by 'actually work'? You can send the radar range to the TDC via the stadimeter.

Er, nothing.

If you want that, then turn on automatic targetting and all the current target data will be fed to the TDC, regardless of whether the PK is on or not.

No, historically, the info was not provided to the TDC in real time, The best that happened was the information was presented to the TDC operator, but nothing was ever entered automatically - that was done by the TDC operator. This was only in the Mark 4, which had a stack between the PK and sound bearing converter stack and the Gyro Angle Solver Stack.

I don't believe it will work in a Gar class. As far as I understand it it should only work in Balao and Gato.

Nisgeis?

I've no idea what interior the Gar uses... depends on what supermod you use. If you can see the range unit, the mod will work, if you can't it won't.

The Torpedo Data Computer (TDC) was an early electromechanical analog computer used for torpedo fire-control on American submarines during World War II (see Figure 1). Britain, Germany, and Japan also developed automated torpedo fire control equipment, but none were as advanced as US Navy's TDC.[1] These nations all developed torpedo fire control computers for calculating torpedo courses to intercept targets, but the TDC added the ability to automatically track the target. The target tracking capabilities of the TDC were unique for submarines during World War II and set the standard for submarine torpedo fire control at that time.[2][3]

This is what Wikipedia says.


Are you going to add a Mark IV TDC or did they even exist in World War II? It would be more accurate to add a Mark IV TDC in case we play campaigns later on in the war like 1944-1945 against the Japanese merchant ships.

Wikipedia is wrong. There was no automatic tracking, as that suggests that the TDC could somehow get the information on the target and generate a tracking solution of its own. The tracking was done by the tracking party, who was a group of guys who plotted the data furnished to them by the radar periscope and sonar stations. The course and speed were worked out and then input into the TDC. The TDC from then on could be used to compare the generated position of the ship to the actual position of the ship and from that work out if the target was faster, or was on a different course or if it has perfromed a zig.

There are no plans to put in a Mark 4 complete, but elements of it are in the mod already, e.g. radar bearing and sonar bearing indicators and repeaters for the generated bearing and range at the radar station for error checking. The Mark 4 was put into later boats (like the Tench class) and some of the earlier mark 3s were upgraded but some were not. It depended on the boat. The Mark 3 TDC could only track a target to a range of 8,000 yards and a Mark 4 could track out to 40,000 yards.

i had it backwards
 

I had it backwards. I thought the ships not to use were Gatos and Balaos.

re Patchman123--Wikipedia for a citaition for something this technical seems a stretch, but it was creative regradless.:haha:

Probably word "tracking" is wrongly understood here!

Actually tracking means some device can observe target constantly or periodically via radio waves, acoustic waves, thermal signature etc. and essentially "plot" its course (now in computer memory) based on such data and sometimes ALSO thanks to some calculations/predictions. Look at TWS (track-while-scan) radar mode present in nowadays fighter radars as a very good illustration.

TDC was an electromechanical analog computer which was fed manually by the crew with target's course, AOB and range. Later it computed target's future locations assuming that target will be constantly moving with the same previously entered course and speed. However TDC did not have any direct link to automatic sensors observing target all the time and thus it could not correct its estimations when target suddenly changed its course for instance. Yet TDC was very helpful during preparation to attack ecause human tracking party could easily detect abrupt target's maneuvers and react appropriately.

I think the latter situation is correctly presented in SH4 even without this mod. However stock TDC does not have any connection to radar or more precisely - human player cannot read exact data from radar and feed TDC with them.

Moreover you can look at German U-boat's TDC (or whatever it was named): in SH4 this device can also predict target's location but it is indicated only by moving torpedo path according to its course without "tracking" target itself!
