1st generation U-boat radar
 

I have just installed the first radar set on my VIIC; I forget the name but it is the first one offered. Do I have to manually operate this or will it run by default? I realize that it is limited in sweep to ahead of the boat and will later be replaced with better sets. Will the Allies be able to detect my radar emissions?

Thanks.

Fumo 29 had its limits,and could be seen if the enemy had mounted RWR

If you have a man in the radioshack just tell him to do a continuous sweep and he'll keep going until you dive or stop him. If you go under a wave, though (like 10 meters or so), he'll turn off the radar and leave it off until you tell him to switch it back on. Makes using the radar in high seas a bit of a drag :shifty:

Also, merchants won't have radar detectors, but assume any escort you come across does. Late war it's pretty much guaranteed they'll know you're there if you use radar.

Haven't used it myself for a long time, but from what I remember, it is activated automatically when you surface. You need to go to sonar/radar menu and tell your man to switch it off.

If you don't, you're going to start being very popular with the RAF, from about 20km out of port onwards, as well as being target number 1 for any DD's in your vicinity.

(Yes, in terms of giving away your location, the emissions are pretty much the equivalent of having a neon sign on your bridge).

I don't bother equipping it, but that's just a personal choice.

The first radar had its limits, you had to steer the boat at any angle for optimal contact,and it was extremely sensitive to high waves, the next generation where you had 360 degrees which was much better, but the radar does not need to be on all the time, when there is a risk of revealing your position

Thanks for the advice, guys. I'll pay more attention to the new radar next patrol.

Good luck! :salute:

Not to add anything shocking but, the allies did not have radar detectors.

They didn't need them as there radar could pick up a uboat at greater ranges than the uboats max radar range. There are no concealment penalties for leaving your radar on.

Possibly not the "RWR" which submarines had,
 

ASV radars,which basically works the same way, with regard to pulses so then you can say to them indirectly, "had it" even if it was radar etc.

K-61 seem we are playing in the same time. I too play DiD and make a new Kaleun at the exact same date my old one died and I too just got my first radar :hmmm:

How do you think it works with fumo 29
 

:hmmm:

Last night I was leaving Brest and was out in the Bay of Biscay when I got a message about radar detected. I now have the "Biscay Cross" on my turm. I dove immediately and eventually there were were three ASW ships ahead of me. I assumed they were a hunter killer unit and avoided them like the plague.

I also noticed when I left port that there were two red bearing lines pointing back into harbour. As I was surfaced I assumed they were from ships in port; this is the first time I have seen this so I have no idea what those red lines were.

Thanks for the advice about radar detectors, Snestorm. I'll leave mine on all the time and see what happens. It may help me to detect merchantmen in low visibility conditions.

The red lines indicate that you have contacts,
 

from Brest, where there is a warships,and in the same way it works when you meet the enemy.

First time I had one of those, I was starting a patrol in Kiel - and the RWR was CONSTANTLY going off. I finally figured out that turning it on in the middle of one of the busiest Kreigsmarine harbors wasn't such a hot idea .......

correction: not RWR (brain fart) but FuMO 29 GEMA radar - and the constant calls from the radar operator about ships detected .....


(thanks Vendor)

If the RWR was constantly off,something is wrong,
 

as you know, it is not a radar, but it captures the frequencies,and it is active as long as you are on the surface
