RFB questions

[Lognoreng]

First of. sry if this was supposed to be posted in the mod workshop. Anyway, decided to give RFB mod a try. After the first confusion with the new command bar layout i was off to tokyo on patrol. And the confusion was total, until going to the old sh3 way of sonar (not at surface). However, i was at periscope depth waiting for a sonar contant to learn how to intercept a ship without the magic contact lines going from my sub. When did get a "Warship bla bla bearing 220". I cheered and went to periscope to see if i could spot them. (Since i already guessed that the sona wasnt as powerful as in stock). To my great suprise i spot 3 escorts and a liner. And they were perhaps 1000 meters away. I thought they were on fire first, until i realised that was the exhaust smoke. Anyway, is it normal to not hear sonar contacts until they are that close? Its Jan '42 (i think. first patrol). Clear weather and 13ms wind.

Also, i didnt have a single plane contact, and i had the radar antenna up all the time..

Appreciate your help..
