[PSUBS-MAILIST] U/W Ham Radio Communications

["Jens Laland" <laland@artematrix.org>]

"One could ask why a radio amateur enthusiast might be interested in
underwater communications. Well, he could be interested in diving and wish
to set up a communications link with the surface, or perhaps he might be
interested in radio controlled boats and wish to try his hand at model
submarines! On the other hand, he might just be interested in another area
of experimentation because here is a field, relatively untouched by the
amateur fraternity, involving different transmission techniques, different
antenna designs and different equipment environmental problems.

The scope of this article concerns the transmission characteristics of
radio waves underwater and the extent to which the radio amateur might
make use of these characteristics.

The article includes examination of the transmission options for what was
lowest Amateur Radio frequency (1.8MHz) when the article was first
published. Of course, some countries now have an LF Amateur band and the
lower attenuation at LF now opens the options further."
