The radio

[dudtorpedo]

Hi peeps

Just started playing SH3 and I got a few questions about the radio. I´m started to play the career and i´m on my 4 th patrol, dec -39.
1) How do u radio for new orders when u have patroled ur area for 24 hours?
2) Why dont u hear any transmissions from other u-boats in the fleet,a bug or?
3) How do u radio for assistance, like a tug or something, to tow u into base? Entering Willhelmshaven manually is fun but i guess its gonna get kinda boring in the long run.

Ty for any answers

Btw, is there a mod or something so u can use the grammophone without the music option on. I kinda like it quiet in the boat.
