For those interrested in how the German hydrophone (GHG) technology works:

This homepage was allready referenced in the GWX 1.03 manual, but only for radar detectors and about the Bismark. This site contains alot more info on other WW1/2 german technology.

Oh dear, they actually have info about "Bernhard and Bernhardine" p24)

Thanks for the link!

That is a very good explanation on this device.:up:

I casualy found the document here referenced, red it and found it very enlightening and was about to open a new thread about it when I wondered if it wasn't the case that it had alredy been discovered and reported in this forum... which obviuosly was the case, as a search confirmed.

So I limit myself to a bump-bump :) ('cause I bet there are new user that will be very intrested in reading it too).

The link of the whole index, just in case:

Many Thanks! :yeah:
