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.
Don't PM me for help as I will ignore it.


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.



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 !


[ I will NOT respond to personal messages, I WILL delete them, use the forum please ]


Was the circuit on page 12 of the linked pdf I supplied no good?
Don't PM me for help as I will ignore it.
