Trying GWX

[Renesco]

hey all I've started playing GWX recently and tbh I've spent several hours and still havent got a kill, firstly there was the first patrol before the war, which took ages because of constant message spam, second patrol I randomly died like 3 times while going up the east coast of england and even that took ages because of constant radio message spam, coupled with extremely long load times, so as you might have guessed I'm finding grey wolves pretty frustrating and not much fun at all to play, so..

1) how can I turn off the constant radio message spam? (shc commander doesnt seem to have the option)
2) why do I keep dying randomly, I thought mines but the mine maps only show mines in harbours, I'm guessing they are everywhere or something and randomly exploding is just a part of the game (fun times)
3) is the crew management window supposed to be extremely dark to the point where I cant read anything?
4) the radio messages that I keep getting are along the lines of (sss 46;55n 36w) are those actual co-ordinates I can use or just RP fluff?
