hello arduino friends
does any one have arduino compartible vlf rx / tx module schematics ?
any help or guidence acceptable !
thank you all very musch for your time reading this !

vlf rx / tx module
What's that?
Rob
vlf transmiter and vlf receiver !
VLF as in Very Low Frequency?
First Google result was this forum message second was this http://www.cdarc.co.uk/talknotes/VLF-G3XBM.pdf
Without more meaningful information that's the best we can do.
VLF transmitters and receivers require very long antennas to transmit properly and operating at such frequencies is not a good choice at all unless you happen to be a nuclear powered submarine looking to receive missile launch orders while still submerged.
Lefty
well it is going to be submerged ! and it is going to receive and send text ! but not more than a Km and not more that 100 m depth ! ALSO ! financially i am not able to buy a VW beatle, for sure not a Nuclear submarine XD ! but thank you anyway !
Fresh water or salt water?
Was the circuit on page 12 of the linked pdf I supplied no good?
salt water for sure !
i've quikly checked them and i thing that they are ok ! haven't got the time to experiment my self on them yet ! thank you very much !
