Some Q's, mainly about lock on range

[Gedscho]

Hello, everybody.

First let me say i think its not really a good idea to have people register just to use the search function of the forums. i really dont know why you wouldnt want non registered visitors to use the search.

now to my question, which i couldnt answer, even WITH the help of the search function

since i installed GWX i frequently "lose locks" on ships. it seems it has something to do with range, but im not sure. im using the 16km view range thingy too, btw.
its like... i lock the contact with the periscope and about 10 seconds later or so i lose the lock again.

this can get really annoying. as i understand it, when im at periscope depth and have no map updates i need to measure the distance to the contact at 0:00 and at 3:15 on my nifty junghans watch. i can then proceed to plot the contacts speed and course.

now how would i be able to measure the distance to the contact without using the stadimeter? i think, while submerged, there is no other (Accurate) way.
and afaik i can only use the stadimeter when i have the periscope locked on the contact.

is there a setting in any cfg file that determines how far a contact can be for my periscope to maintain the lock?

im pretty sure i didnt have this kind of behavior in vanilla SH III, but it didnt have 16km view range in the first place, ey.

another question i cant answer would be the options of the radioman. i know what "feindfahrtbericht senden" does. but im not EXACTLY sure of "Fühlungsmeldungen schicken" and i have no ****ing clue what "Kontake melden" does. i always get a "Keine Funksprüche erhalten" on that one.

any help appreciated!
