RADAR mast failed ?

[Kapitan]

in the process of doing my first mission in K157 Tigr (Akula I improved) i have had a few problems.

ive been at sea now for 42 hours as i left base yesterday (dont use time compression computer runs 24/7 and so does DW)
now the bearents sea is the main area where i plan to test my boat cause there is a diffrence between the akulas i just want to know the diffrence anyways.

up here merchant traffic is quite high in the first 3 hours of leaving port i have already picked up 4 vessels 3 ships and a submarine (submarine possibly american) two of the ships are port control ships (a krivak and grisha) and the third is a merchant oiler (visual classification).

i poped my RADAR mast up to get a firm fix of the ships i was at 18 meters speed 4 knots and my RADAR worked perfect classified the ships.

now 42 hours out of port my RADAR doesnt want to work i again come to 18 meters 4 knots raise the mast and nothing the orange haze that normaly sweeps around the RADAR screen is gone and nothing is picked up.

yet i do know there is another two ships (two frieghters) very very close (about 2 miles) my radar is set to 40KM range and the rings set to 5000

can any one help me please?

the mast is not broken i can raise and lower it still and its not on the damaged list so its still oprable

can any of you help im stuck and i dont want to turn back cause of a stupid glitch anyways where im heading i dont realy need it but i do need it right now because im transiting the bearents sea and i realy dont fancy becomeing a figure head for a ship

cheers
