Hi Rubini,
i just reviewed my setting, but it must have been an GHG hydrophone. In my currently used basic.cfg, delivered with Testpilots great Type VIIB Mod, hydrophone standard equipment is "1270" for every year, which is determined as GHG at the bottom of this cfg file.
I also took a look at the foredeck, but no KDB device was mounted:
At last, i could have proved to have a GHG immediatly, because i had to turn my boat to get contact to the DD directly ahead of me, because of the deaf area of the GHG around the bow:
Generations of SH3 beginners (including me) claimed this effect to be a bug without knowing anything about the geometric restrictions of this hydrophone...
To come back to what you wrote: I´m not sure if i understood completely what you meant: in my tests no ship was at a distance closer than 12km. I did not test this because i thought within this distance a ship always is to be discovered, even when using your mod and being in shallow depth?
I did another test with your 1.0 version which showed a ship´s contact by GHG at periscope depth closer than 12km:
To another ship at a distance of little bit more than 12km, contact was lost after rising to PD from a deeper depth of approx 17m:
So in the end, it seems to me that version 1.0 works perfectly how you described it and how i expected it.
Greetings
