When do i get radar?

[iven72]

I have a triton class sub and no radar. I can add a SD radar but it don't do anything
when i go the radar station i can't even turn them on It only has a PPI radar and a A-scope radar. and i can't turn eather on.

Your SD radar is always on and you will get SJ mid to late 42, then the scopes work.

Essentially what you did was use your renoun to "pre-pay" for the surface radar. It's one way of guarenteeing when it does get released, there is no chance you might now have enough renoun to pay for it while in port. Being in port at or after release time will allow you to install it.

SD Radar is air detection radar - detects airplanes. It is always on. It
doesn't have a radar screen.

SJ Radar is Surface Search Radar - detects ships. You have to turn on
everytime you surface. It has both the PPI and A-Scope. Generally
becomes available in the middle of 1942.

Ahh, I was wondering about that myself.:up:
Question: What is the difference between the A-scope and the PPI?

Nothing to do with radar. But what is a triton class sub ?

The A-scope is an oscilloscope display. Basically you turn a wheel, and when the radar head gets a return the scope shows a spike that indicates the range to target. The bearing is read from the wheel showing where the head was when the return came back.

PPI stands for Plan Position Indicator (if I remember correctly, anyway). This is the familiar radar display. It shows a top-down view with the transmitter in the center. You'll see the line of current bearing on the display, sweeping around, and any returns show up as dots on the screen. Distance between you and the dots is representative of the distance between your boat and the contact.

I got my SJ surface radar on my porpoise and later on my gato in July 1942. Had enough renown points to get that and the improved SD Radar. I heard there's a SJ-1 Radar later on.

SJ-1 becomes available on the Balao class somewhere between mid-late 1943. It changes the radar antenna head on the sub.

Thanks Quillan, just what I wanted to know.:up:
