well,
whatever it is, I like it - and that' s what matters probably..
but I still, I tend to believe that it has to be sth buried in the sand,
This beach is pretty isolated - there' s not much going on there - Just a c=
ouple of houses and a tavern, or sth like that. No radio stations, cables o=
r people using mobile phones.. Well, in our century electromagnetic radiati=
on could be everywhere, of course.. There is a military airport somewhere i=
n the greater area, indeed, but we are talking about a distance of more tha=
n 10 kms. It' s highly unlikely that their radar would cause such a sound u=
nderwater..
The most logical thing to me is that some kind of crustacean or sea-worm li=
ved there or sth else. (it' s not flattering to record radar sounds in a be=
ach anyway..)
just for the record - The hydros were a set of dolphinEar Pros, I bought th=
em second hand from a guy that bought them together for a never-to-be-reali=
sed-project - so probably they are of the same set - plugged into a marantz=
PMD661 recorder.
