How does the copper pair feed out over the sea? Is there
a ginormous drum on the clifftops, perhaps?

OK it is a computer soundcard solution but would a netbook with a solid
state drive to cope with the foundation not be viable? Small, compact, uses
little power and will drive Hell easily and is simple to use. With a little
dismantling and repackaging, can easily be made watertight and even more
shockproof and a custom Linux build can make it a turnkey appliance.

That would surely be a bit primitive in today's world.

If your main concern is the noise cancelling and your operatives can
manage to operate a radio then the Motorola Mototrbo range of radios
have exceptionally good noise cancelling. I have installed them in
paper mills and power stations where it is impossible to speak to the
person next to you because of the noise and they still work well. On
one dem' the bosses refused to accept the operator was in the generator
hall until they saw him there because the audio quality was so good.

Sorry to all the wingers on uk.radio.amateur these are digital,
hence the good audio processing. :-)

I don't use Hellschreiber, but it certainly works on a small Asus
netbook, under Linux.
