GWX Question: XXI snorkel mounted antenna

[Pablo]

@Stiebler:

I'm sorry, but in reading your source information I don't see where you can draw a conclusion that the GWX range is incorrect, since radars with meter-length radars were still in use and we need to account for the U-boats ability to detect them.

@P-B:

Looking back at my earlier post, I see that I was too vague about the NSS_Uboat21.sns file. (Item (2)).

In your new 'LateSensorsXXI' mod, locate file NSS_Uboat21.sns.

Find the radar-warning/FuMO391 section. You should be looking at 'Sensor10' and 'Sensor11'. Both have NodeName=R02 (the position on top of the schnorchel).

Change the ENDDATE of sensor 10 to Enddate=19431231. (I'm assuming we're still trying to get the schnorchel radar from 1 Jan 1944).

Change the STARTDATE of sensor 11 to Startdate=19440101.

When you sail out of port, you should now see the Rundipol rwr on top of the schnorchel. When you see that, you've got a schnorchel-radar-detector.

I've tested it in a Type XXI around the north-west of Britain in mid-January 1944 - it works.

But how come you have access to a Type XXI at all in January 1944? I had to modify file flotillas.cfg before I could get one to come up on the equipment screen for the 11th flotilla starting a career in 1944.

Also: You must have a crewman in the radio compartment to receive radar warnings!

I take your point.

However, by 1945 most aircraft/warships were using short-wave radar because it is more precise. Also, the less precise long-wave radar could not detect the schnorchel except under ideal conditions, so it posed no threat to the U-boat.
Therefore any schnorchelling U-boat would have to assume that an attack was likely to be made with the assistance of short-wave radar. For most air attacks, the U-boat would receive very little warning.

Players of SH3 use time compression, therefore it is necessary to use a range longer than 1 km for short-wave radar. I have found 5 km is about right to give the player time to react.

Stiebler: Thanks for the clarification - i was only modifying sensor 11. as to Jan availibility of XXI - i do not have the XXI at that time i am trying to get the Snorkel mounted antenna from its availible date on 01 Apr 44. Your instructions do not change just the date obviously. Thanks again! I will try this when i get home and post result.

Just to confirm -

NSS_Uboat21\NSS_Uboat21.sns:
Sensor 10:
Enddate=19440331

sensor 11
Startdate=19440401

cfg\basic.cfg:
[EQUIP 5]
Year7=1944,
Month7=03

Making thes changes in these files should make it work right?
thanks again for your patience and time mate.


Edit: Thankyou Stiebler, have made the changes and it works like a dream, again; thanks for your time.
