Short wave at 800 metres depth.

Post by colly0410 » Wed Aug 27, 2014 10:07 pm

Just been watching a film on 'Movies for Men' (Freeview ch 48) called 'Sun Attack'. There were two submarines at 800 metres depth talking to each other using Short Wave radio! & here was me thing that they'd have to use 'Very Low Frequency' or even 'Extra Low Frequency' radios at that depth. Oh how I laughed.. :)

"Director's Licence" methinks! Conceivably some sort of modulated carrier acoustic link?- but not very secure and short-range.

Once you're beneath the waves, you talk to no-one. You listen, but you say nowt. That's the idea of submarines!

Indeed stealth is the point of subs.
Radio (can be aerial between towed buoys) is seriously unstealthy.
Hydrophone (direct audio or ultrasonic sound) is not a good idea either.
