I was looking at the RAOBF and I think I need some help.

So far at x6 scope I am seeing the following.

So this looks like it works for scope x6.

Does anyone know how to work for scope x1.5?

I do not know anything about this specific edition of the Range and AOB finder (don't have SH5, so not familiar with this mod), but I do know how it works in general. (I used it from it's inception with SH3) I think you are looking at the wrong place for the optical length of the target (green arrow). It should be found on the inside scale of the middle (moveable) wheel. That will be aligned to the AOB as calculated by the device. In the second image you have the green arrow at 6.5 (650 meters range), instead of 7.5. So that one is certainly wrong. The scale that you have the green arrow pointed to is only to be used for range (number times 100 meters) values.

BTW did you first calculate the range, and then turn the wheel from the target (mast-) height value to the target length value? That is the proper way to set up the wheels for the AOB calculation!

see here: http://www.subsim.com/radioroom/show...postcount=3440

From outside to inside scales:

most outer scale : real (mast)height for range, or real (ship)length for AOB

outer scale of moveable wheel: range only (number times 100 meters)

inside scale of moveable wheel: optical height or (halve?) length as observed in the scope.

most inner scale: AOB scale, 90 degrees is index to which observed height should be aligned for range measurement in 6x zoom.

I'm afraid that is not how the original RAOBF developed by OLC, Hitman and Joegrundman works. The scale pointed to by the yellow and green arrows in Trevally's images is only to be used for range. The inside scale of the moveable wheel is for observed height and observed (halve)length. Darkwraith's solution seems to work. But it can't, as the observed halve length is 10 marks, but (his) 10 is left of 90 degrees. And that is impossible in the formula. There is no angle that makes the sine of it become bigger than 1. (which is what the 12-o'clock position represents) What he does is cheating the numbers. Still, using 10 on the innerscale of the moveable wheel also doesn't work. Since it points to 15 degrees AOB. And that is clearly not the right angle based on the view. Somehow this yellow scale in the scope is wrong! The observed (halve) length should have a value of about 38 marks.

it's not based off of them that's probably why. It was developed using Karamazov (KiUB User Guide) as the source of information as to how it works.

Thanks Pisces:up:

I will try some more tests with the information you have posted.

Here is the document I based the RAOBF off of: http://rapidshare.com/files/44012975...ser_Guide_.doc

karamazovnew just took the RAOBF from the U-jagd tools, simple as that.

that's good to know :up: So let me ask you this, is the way I implemented it correct or not? If not, how is it supposed to work? I want it to work correctly and accurately.

Check out these video tutorials.They lay the whole system out. They show two different versions of the interface, but the function is the same. "Fixing" yours should be a "simple" matter of calibrating the graticules to targets of known range/AOB and editing the RABOF discs accordingly. You might could even hunt down OneLifeCrisis and pick his brain on how he calibrated his version.

Some good info - thanks all:up:

Watched the vid then checked out and tested the clicks

As you can see I know the range to target is 720m
I know mastheight is 40.4
The 90deg mark shows that the mast should be 2.25 clicks not 6.75

Ok in this one I match range to ship lenght (111m)
5.5 clicks on the bow should be 64deg AOB
Actual was 70 deg and should be 5.75 clicks.


Both pics at at 1.5 zoom.

I will read and test the link from TDW next.

:hmmm:Some not right. I just tested a diff ship and this time the bow should have been on click number 32:o

Think I've been at this too long today:88)

I don't actually have sh5 so i haven't seen it in action, but i can see that no one has changed the actual ring markings that i put on. People have added better reticules and markers on the edge of the rings.

The middle ring should freely spin; if it does then it works properly!

now i look at your reticule, i notice that the vertical markings are half the spacing of the horizontal, why is this? Are vertical meters smaller than horizontal?

There are broadly speaking only two areas of error with this. One is if the reticule markings have become confused, the other is if the wrong scale of RAOBF is being used. There are two RAOBF wheels "out there", one set by default to 6x magnification and one set to 10x to deal with GWX scope magnification. If you took it from karamazovnew then it's i think certain that this is for 6x magnification.

How do you know the range is 720m?, anyway in the example, I notice you set the range to 7200m, not 720m

and an AOB reading of 64 instead of 70 can be described broadly as successful. Certainly good enough to shoot with.

EDIT: OK I think i understand the problem now. The point is you are using this at 1.5x, rather than 6x while this RAOBF is set naturally to 6x, therefore there needs to be a division by 4.

If you had set the range to 720m rather than 7200m, it would have shown 22 marks, not 2.2.

However you are using 1.5x instead of 6x so the number of marks needs to be divided by 4. 22/4=5.5, which is it least close to what it does show, although not perhaps close enough..

This implies that the vertical scale is half the size of the horizontal precisely for measuring range at 1.5x, while the horizontal is designed for measuring at 6x and from a position of lock onto target so only one side of the target is measured :hmm:

Seems a slightly long winded way of going about things compared to the simpler original approach of all measurements at same magnification, but i guess there's a reason for it

Thanks for the help joegrundman:up:

I think I now understand most of how this works.
I am wanting to test the clicks on the RAOBF.

I have measured the info from map.
Range = 850m
Mastheight = 28.4
zoom is x1.5

Testing range.


http://img189.imageshack.us/img189/7844/pic1px.png

Mast should be at 3.5 clicks but shows 4
I use the bottom right marker for zoom x1.5

OK next I am testing range with x6 zoom
I use the 12oclock marker for this.
All values are the same as above.

http://img585.imageshack.us/img585/3918/pic2n.png

Ok here we see the mast should be at 13.4 clicks but is 16clicks

Ok next testing AOB at zoom x1.5
Ship lenght is 120m
Range is 850m

http://img88.imageshack.us/img88/1889/pic3v.png

So 4.5clicks x 4 = 18clicks
= AOB at 18.5deg

Actual AOB is 112deg starboard
so 112-90=22deg or 21clicks
21clicks /4= 5.25 clicks rather than the 4.5 shown.

Is this close enough for AOB:06:
Do you think that only the vertical clicks need changing:06:

Yes, your steps are done correctly, despite vertical graticule marks being wrong.

Instead of multiplying by 4 if you use the 1.5x zoom, you can also drag the moveable wheel counterclockwise from the lower-right index to the 12 o'clock index. And then look at the AOB value aligned to the number of horizontal marks that you see on the graticule scale. That works the same.
